Get More Power Out of Your Subaru Crosstrek In 5 Minutes | Air Intake Box Charcoal Filter Delete

[@ironman1518.]

Been using K&N's in all my cars and motorcycles since 1970's!! Great filters no re-buying just clean and re-use. In my 2013 after removing the charcoal filter it has a little bit deeper intake sound NOT real loud.

[@PatrickKasilag]

Right! This is exactly what I was going for

[@MitchellSorensen]

just checking back after your modification to see the inside of your air box beyond the k&n to see just how much grime got past. Ive always run k&n in all of my vehicles and i have one in my crosstrek right now. I have yet to cut out my carbon filter yet and would like to see the difference between the two of us. id love to help you on the next video and could send you pictures of my filter vs yours for future viewers... and science. i have another month before i clean my filter. hope to hear from you soon.

[@bittidude]

these filter are great on racing cars with high revs......seen a test of these filters (believe it was on youtube) and they do work, low to mid range revs it doesnt do much but at higher revs it makes a diffence. Like you compared running with a mask on, walking and jumping boulders no problem, 100 meters sprint with full power it will be harder to breathe

[@hurricane0460]

After 11 months with this mod have you noticed an increase of fuel mileage or a decrease?

[@wed_ward]

That carbon filter is part of the emissions control, so technically removing it makes the car non-compliant. Depending on the state inspection process - a small gamble. However, you should check out the dyno results and other details done if you really want to do this - kzbin.info/www/bejne/fGKtnoKBgKaar7M - otherwise the K&N seems like a no-brainer.

[@RKmndo]

Not just more power. I also got better MPG after upgrading the filtering. I got 46+ MPG on a tank with my 2016 2.slo/CVT...with stock tires. Now I use tires 1“ taller. I can still get mid-high 30s hwy at 55-60MPH.

[@PatrickKasilag]

That's awesome!

[@vicant2961]

what's the exact size of your tires? please share

[@RKmndo]

@@vicant2961 225/60R17. Stock on 1st-gen Crosstreks is 225/55R17. I'm currently running Falken Wildpeak AT Trails.

[@carloscarmona7667]

I have a 21 crosstrek sport with same tires now and it has the 2.5l, did you change just air filter or did you also cut out the carbon out of the box like video,please advise,thanks.

[@RKmndo]

I removed the carbon filter. The airfilter is a dry, cotton, high-flow filter from DNA. I also use 0W30 oil, with a quart of Duralube.

[@moosmya]

can we get an update ? !!!

[@SkyMine911]

I have a 22 XV, but I don't have the same screen you got in the middle between the gauges, and I couldn't modify the middle screen to make it simple just like yours since I think it looks much better. Do you know how? I tried fiddling it in the settings but nothing came out unfortunately.

[@Smithcraft1]

It looks like it's just the speedometer screen. You use the switches on the lower left side of the steering wheel to cycle through the different displays.

[@chemuzio-ssir2015]

Im still under warranty 😭

[@anthonyjulson8840]

They aren't looking for a charcoal filter. Mines been out since I brought the car home with less than 100 miles.

[@keith606]

Couldn’t get all the adhesive off and wound up using a wire brush. What would happen if a small speck of plastic or adhesive debris were to be sucked up?

[@PatrickKasilag]

Nothing good.. I would suggest taking a razor blade and getting as much off as you can. If it won’t come off with all that effort, then it’s unlikely to come off on its own into the intake.

[@tysonduquette1414]

Does this affect a cars inspection?? I live in NY where we cant get away w/ anything!!!

[@odinschulte4759]

How does the crosstrek do with the bike on the back? I have a crosstrek and I'm thinking of getting a honda crf250.

[@PatrickKasilag]

It does just fine with my 2022 KLX140RF, even for long road trips. I hauled my 2007 YZ250 with it a few times, but only for short trips (feels sluggish with my big bike and car packed with gear.)

[@iphone3gsdivine]

Damn I got a crf450 I guess that would be a problem for me lol

[@PatrickKasilag]

@@iphone3gsdivine It's the tongue weight rating that's limited on the Crosstrek. Does yours have aftermarket / heavier duty suspension?

[@SeanSR]

I have a 5x8 trailer and 1 quad and 2 full size dirt bikes, pull it about 15 miles each way to our riding spot. Been doing it for about 5 years now and never had a problem. kzbin.infocZB8oVU2Cn8?si=qxh2RK8skTCGoQPM

[@spectre1006]

will this affect smoging the car in CA?

[@Smithcraft1]

It might depending on if it is required in the visual inspection. If you wanted to, you could purchase another housing and have one that you put on for your tests that has the filter, and one for the rest of the year that doesn't have the filter.

[@jamesbailey3593]

I saw the thumbnail on the video with your dirtbike on a hitch rack… has that worked well so far and not been too heavy?

[@PatrickKasilag]

I’ve loaded my Kawasaki on this hitch at least 20 times this past year, it’s worked well. But then again my air cooled bike is only 215 lbs. my 280 lb Yamaha feels noticeably heavier when driving though

[@bamaboy145]

Which hitch do you have on the trek? I was worried about all the weight on the hitch if I put a full size bike on it. I’ve got a yz that looks similarly built to yours and then also a 250f. Would be nice to use the trek to haul them (one at a time obviously) without a trailer

[@ShredRMK824]

Pzev component is lame. How much gas fumes from a 4 cylinder and it doesn’t get me HOV lane so bye bye...

[@car24dude]

I would clean it with every oil change.

[@jacobmartin112]

I might try this however what I'll do is probably buy a replacement Upper Case (46051FL010) that I'll modify then put the factory one back on if I need any warranty work on it (since I have just under 30,000 miles and wish to keep my warranty).

[@belowme4927]

subaru already has designed their air filters and intake for maximum efficiency learned that back in 2004 on a wrx i had. replacement air intakes are a waste of money.

[@paranormalwheelers]

Wouldn't the computer make adjustments after a awhile

[@Amerteratsu]

I am thinking about buying a Crosstrek and modifying it for off-roading in Northern California. What year and trim model do you recommend?

[@lolvids2]

get the bigger 2.5 engine for sure

[@constructapex2021]

Would taking the charcoal filter off show up on emissions test?

[@PatOutdoors]

No it will not. And the inspector should have no reason to open up your airbox to check for that

Hola este filtro se puede instalar en un Subaru xv turbo diesel? Gracias

I’m still under warranty too? I only have a power train warranty so in theory wouldn’t modification of something not related to the power train not void the warranty

[@fyshi6226]

In theory it wouldn't but its likely they would find a way to make whatever you did a potential cause to avoid a claim

[@FeliksTaylor]

Does it fit the base 2018 Crosstrek models?

[@PatrickKasilag]

It should fit all 2018-2023 models

[@louisd9795]

This pre-filter is not fitted on European Crosstreks 🤔

[@PatrickKasilag]

My point exactly. Some people in the comments talk about how bad removing this is when it doesn’t even come from factory on older models or foreign models..

[@louisd9795]

@@PatrickKasilag It actually looks 😅, I'm French and I don't have it on mine, there are a few pieces that are different, while mine is from 2016. But unfortunately it's extremely hard to find accessories here.. like all the LP Aventure parts, the lift kits, everything is complicated to get..

[@JakeRogue]

So swapping out filter but additionally getting rid of the charcoal filter? Are you supposed to replace that charcoal filter in normal maintenance?

[@PatrickKasilag]

It's not part of routine maintenance. I can't imagine it gets that dirty though since there's the filter in front of it and most cars don't even have that. Do you still have your stock FR-S intake?

[@JakeRogue]

@@PatrickKasilag yea besides the drop in filter it’s all stock in the engine bay (excluding oil cooler)

[@EdibleOutdoors]

Any update on the modification? Did you notice a difference?

[@PatrickKasilag]

Little bit more response down low and you could hear the induction noise, but you're not gonna feel a just a few HP. Maybe if you change the exhaust, manifold, tune, etc then you could physically feel a difference.

[@SeanSR]

@@PatrickKasilag what happen with the mpg? up/down?

[@plightn]

Here is the thing though, they let more air in but that includes particles. But I doubt that makes a difference in 5-6 years of ownership.

[@PatrickKasilag]

Right, and most cars didn't even have a charcoal filter in the airbox from factory anyway (for decades)

[@PoleVaultProject]

I agree I’ve been an auto mechanic since 2013 and I just bought a cross trek and noticed this extra filter. I also noted a very acknowledgeable change in both throttle response and pickup after 3,000rpm. Before I felt like the power and was extremely linear. Maybe a Flow Bottleneck from the charcoal filter.

[@benjaminless3269]

The charcoal filtre is designed for engine shut-off - preventing positive crank case fumes venting to atmospheric air and other hydrocarbon emissions escaping, back up through the intake track such as unburned fuel from port injection systems. It's an emission thing.

[@jacobmclendon4387]

This was day 1 of being a Crosstrek owner. Literally. Went with spectre brand filter tho Mine is a 2022 premium base manual, and going up hills it saves me from dropping a gear after I switch back to paper while the spectre filter was drying out for a couple days

[@chrish6373]

Does it change the Intake sound? Would like to get a little more grunt without paying for a cold air intake or sub-performing cone filter. Ideas?

[@PatrickKasilag]

It's a very minimal change in sound, but yes it is a bit louder

[@anthonyjulson8840]

If you want more sound, pull the resonator off the bottom of the intake box.
