[@jonathanlopez1347]

Equal Length Headers + Cyl 4 Cooling Mod are a huge part of equalizing EGT across all cylinders. The Subaru EJ Knock Control System is strictly bias to Cylinder 4, as it runs 1.5 degrees of timing over over all cylinders. Essentially, Subaru's thought process is "If Cyl 4 isn't knocking, we're good." Timing is everything. It's how power is made. ELH and Cylinder 4 both contribute to a safe increase in timing, although Octane is the major contributor.

[@robk5745]

I've done hours of research, learning everything possible to add reliability to my track/street car. You've hit the mark on this one on every point. Oil and cooling are really the highlights. Don't forget a nice smooth tune and some one step colder plugs too ;)

[@Smeedia]

Definitely 🔥 a fluidamper or ATI super damper is another good one to add to the list 🙌

[@Xavier4514]

I’ve watched this video a few years ago and I’ve installed Perrin AOS, cylinder 4 mod, Killer B oil pan +tube +tray plus other reliable mods.

Great Vids, keep it up! On the oil pick up/windage tray/oil pan, sounded like you thought less important for certain years.

The older gens used a thinner material for the pick ups, in 2011 Subsru revised the pick up and increased thickness but it is still a potential problem. I would suggest swapping it out just to be on the safe side.

Just picked up a used 2020 WRX and I’ve been going crazy researching reliability as I do know Subarus has a bad reputation in terms of blown engine. I stumbled on your channel and honestly I feel like all my worries is put at rest. I definitely want to add an AOS, killer b oil pickup pan. Any suggestions on more reliable parts? Or is killer b oil necessary? I’m probably at most, add an air intake and a cat back exhaust all of which will be pro tune. Awesome channel🤙🏻

6th Gen Celica...

Just proves what you highlighted in your video is exactly spot on and if undertaken, will make our Impreza WRX/STi more reliable for long term ownership 👍 👏...

Nevertheless I'm thankful that you've made this video now... Better late than never 👏 Cheers 🍻

@@Smeedia It's currently for the brz/86/frs platform in terms of ready to go mounting but works on everything for fabricate mounting. Verus is working on a newer WRX/sti mount. It's also quite a bit smaller than iag and Crawford ones, and supports drainback too. real_awd_cars is my Instagram and I have photos of it on my 04 if you're curious.

By the Killer B Holy Header with there ceramic coating and buy a ceramic coated downpipe if you can. A downpipe with two ports so you can run a wideband sensor. You will be so happy you did in the future. Killer B’s most current design with the one piece collector sounds damn good.

Thanx for the pro tips Smeedia. Will the Mishimoto radiator have enough clearance to the pullies and cooling fans? Or is there Mods or extra space needed in the engine bay? Also is a catch can any good whats the difference aren't they doing the same job accept one has cooling aspects? Sorry if noob question but educate me please. Cheers. Great content as usual.

I'd bump the radiator up the list if you live in the southwest. My ambient air thermometer today said 121dF and the car was struggling, coolant and oil temps were high and the intake manifold temps were getting up to 150-170dF while sitting in traffic.

I’m wondering is it safe to a noob like me to install all these myself or it’s better to find a professional tune/install store to do this and learn more? Would these mods void the warranty or only something touches ECU void the warranty? Great thanks again for the video! And this is actually my first ever KZbin comment after 10 yrs using it lol

[@Smeedia]

Congrats in the car and welcome back! You can definitely install these modifications yourself. None of them are too over the top difficult. Just keep in mind Subarubof America can be relatively picking with mods and warranty stuff.

I have always loved the WRX/STi platform, and last year finally got my hands on a stock '08 WRX for $4k expecting to have to do a rebuild (random cylinder misfire). I pulled the engine and heads and the cylinder bores look great for 135k miles, so I think it just needs some head work.

That's a good question... and is it worth waiting to do it in stages, like do these, then a tune then your air intake system and tune again then say boost tune again or wait till you do it all including your suspension etc then tune? Or do what you can afford for a while eg I could probably realistically afford maybe this stage stop for about 6 months save up and wack more money or should I tune between? sorry to hi jack your question man!

[@Phantaystic]

@@andrewpaige9152 it's all good bro! Everyone has a different budget. Pro tunes are quiet expensive if you're to do multiple tunes, about 350 a tune usually. I'd say do it in stages if you can afford the tunes. If not, hoard all your mods then tune it in one go. Which is the route im planning on going. Since smeedia confirmed that the supporting mods don't require a tune. I'll be doing those before power mods. But I'll be running MAP stage 1 just for the extra power being fully stock.

So I have an aftermarket set of unequal length headers on my sti. They are tomei ones. Is that still technically better than the stock headers? I noticed the stock headers are way more restrictive than the tomei ones and the piping size is significantly bigger on the tomei and looks like they have way higher exhaust flow. So even though equal length would be the ideal choice wouldn’t aftermarket unequal length headers still be better and still somewhat help with reducing knock? I noticed after Installing the tomei headers my overall knock decreased a good amount still.

[@djteako]

Up here in Canada most shops DON'T recommend running an AOS - even the heated ones such as the Perrin or IAG. Unless of course you park your Subie for the winter(why???) There have been too many cases of the AOS freezing up and causing total engine destruction up here. It happens once you get below -20 deg.C

[@Smeedia]

I have seen some of the fourms talk have talked about the issues and the announcement IAG put out and I'd agree with you on that one.

How will a larger radiator affect the fitment of a front mount intercooler? I want to get a front mount at some point and I would also like to get a larger radiator.

[@Smeedia]

It won't. Thr rad sits behind the core support and the intercooler sits infront of it 🙏

[@Torpedomtb]

Ron Davis has a rad for the Subi and they are the KINGS of Radiators. That is all they do is radiators..

What can I do with a Ej25 engine on a 2008 Impreza 2.5 non turbo automatic to ensure longevity of my car? I have a cold air intake (not short ram) and a 3' dual exhaust catback as the major modifications. The catylic converter is a walker brand about a year old and carb emission compliant with unequal length headers. The entire exhaust pipes are basically replaced as are other general maintenance parts (spark plug/wires, ignition coil, valve covers. Currently, the car is being serviced for bad compression and internal burning oil most likely it's going to be a piston/valve and seals repair. It also had a head gasket repair almost a year ago also. Currently, the car has 177,740 miles on it. Any ideas as I'm not ready to get rid of it just yet. Just a side note I replaced the spark plugs (NGK) and wires and the cars expected avg. mpg. reached as high as 30 avg. mpg

[@Smeedia]

Honestly just stay ontoo of maintance, add a catch can ans drive the car. If you really wanted you could do a larger rad but thr N/As don't have a big aftermarket standing unfortunately

[@bmoore8853]

I was surprised you didn't mention the Killer-B AOS, any reason you don't like it? BTW, great video, i have all of these parts except ELH installed on my cars, waiting for a free day to install my #4 cylinder mod, but yeah I agree these are the parts to keep those EJ's rumbling along, my auto 04XT has almost a quarter of a million miles and is still far more reliable than the jeep liberty (70K miles) my fiance used to drive, i insisted she start DD'ing one of my XT's and she is hooked now. Gotta love that mid-range torque on the highway

[@Smeedia]

I've never ran the killer B AOS so I cant speak for it but from what I've heard it sounds like a good product. Hot damn that thing is still going strong!

[@MKNYC_]

I’m running a stock WRX and I’ll be leaving it stock at least until warranty is up (I hope, I have to stay strong), should I install an AOS anyway or does it not matter as much in a stock car?

[@Smeedia]

It makes a diffrence on a stock car but will void your warranty, I would suggest waiting until it expires to install

[@apreviousseagle836]

In your opinion, with a car like mine (stock STI down to the paper filter with 107k miles on it, well taken care of, unknown how much the previous owner pounded on it, but runs well, pulls hard, no engine oil burning, and no symptoms of oil/coolant fouling. Short of a compression test to confirm, which will get done soon, the car "seems" to be in perfect shape). And so far, the only mod I've done is an Accessport, and I'm running the Stage 1 ACN 91 map with Canadian 93 octane. 1. I plan to do the cylinder cooling mod ASAP! but how safe is to go for the occasional WOT run before this gets done? 2. Is it worth getting an AEM Dry filter to replace the stock paper filter? 3. I'm currently monitoring Coolant temp (highest its gone is 191f), feedback knock (highest it's done is -2.8, and usually only for the first second of hammering it hard on 2nd or 3rd gear), and DAM (has never gone below 1). Does that mean I am in a safe range to blast the car once in a while? 4. The ACN91 Map has 8psi on I-Drive, 14psi on S-Drive, and 17psi on S#. I am scared to try S#. Am I being paranoid? I'm tempted to try how it feels. What do you think? Awesome channel BTW, I'm soaking in all your great videos!

[@Smeedia]

With it all stock I wouldent worry too much, just wouldent do pulls 24/7 lol Imo I'd say get an SF intake over the panel filter And all normal values, I wouldent stress any of it 🙏

[@5amfishing59]

I knew there was an exchange rate but 93 Canadian octane = CA 91 ? Lol

[@apreviousseagle836]

@@5amfishing59 After a few months of driving the car, and a couple of weeks of trying the regular 91 octane OTS tune (not the ACN 91) with both Canadian 91, and Canadian 93 and 94, I saw no difference whatsoever in the #'s reported by the AccessPort. Using 91 on the regular 91 tune did not cause any knock, or any other issues with the car. BUT since it is a higher mileage motor and I don't want to spend $5k+ right now to replace my motor, I put the ACN tune back in it, and I just use 91 octane now. I think Cobb is being VERY conservative since they probably don't want to have any controversy with Canadian customers blowing their shit up. But I'm sure there is some truth to the quality of the gas vs in the non-commie states. The car was definitely snappier on the regular 91 tune. I never tried the 93, but if I'm brave, maybe I'll try it soon with a tank of Canadian 94

[@gizengar111]

Would an AOS void my warranty? I'm about to pick up a 2020 wrx real soon with 26k miles on it. Or should I wait until it hits 5 years or 60k miles then get an AOS?

Do you know if the Killer B oil pan still fits under the under tray on a 2011 WRX? Thanks!

Yea it does 😁

Hey big guy! Would any of these mods void the warranty from subaru?

Yes they would 😫

[@danielreimer6841]

What you think about the Crawford V3 AOS that doesn’t use coolant but is located right on top of engine to get the heat off of it?

[@Smeedia]

I think it works but out of all the options is not one of the best choices. The ones that run coolant IMO are the way to go

[@GolfCoyote]

20k miles on my HKS ELH, no problems here. Solid name brand and solid price.

[@Smeedia]

Very true 🙌 only issues I've ever really had is fitment before. Never ran HKS but thank you for adding it in!

Do you recommend the Oil Pickup for the FA as well? Also, any thoughts on the Perrin aos?

[@Smeedia]

The oil pick up is not a bad idea for the FA20 and perrins is good from what I have seen, I used one for a little while on my old 2011 STI and it did its job

[@BlackWat3rGTR]

Killer B pickup on the FA is a must because even though Subaru improved their oil pickup, the screen on the pickup is still shit. Get the Killer B and call it a day.

[@timurbarucija5547]

looking at catch cans and aos, just wondering if you have any experience with both and which is more effective? i really like the look of the radium engineering dual catch can set up and dont mind taking care of it but is an iag aos more effective by chance....?

[@Smeedia]

Its all personal preference, I run the IAG AOS on my STI and the radium duel can set up on my BRZ. Both are good options and work great. Just remember to empty the cans if you go with radium 😁

Appreciate the support, make sure your looking for any modifications done to the car. The last thing you want to do is buy a car that someone else had put parts on and not tuned for it, or installed incorrectly. Outside of mods, look in fender wells for rust, service history and the normal fluid levels and what not 😁
