Subaru WRX Modification & Maintenance Guide

[@SCarolinaX]

Having owned this car for almost 3 years I go back and watch these type of videos to make sure I’m not missing anything I should be doing. These cars are amazing and I am so glad I built mine for me. I don’t try to race, I drive it daily and take it to mountain passes. Close to 100k and still going strong. Your videos definitely helped a ton!

[@WRXGarage]

Great to hear!! Glad our content has helped

[@deigobams3]

I drove my 18 VA for 100,000 miles Cobb stage2+ 93 OTS. 130,000 miles total. Most important thing is how you drive it. I drove like a normal human and when I sold it to buy my VB it ran perfectly, never burned or lost any oil at all, and never had to fix a thing. Don't drive like a dummy.

[@Coldouteh]

What made you sell it?

[@johngalt6159]

My 16 never had a problem just hit 85k. Changed oil early every time only run mobile 1 and 93 gas she runs great. Like you said don't drive like a dummy and they are fine.

[@waybach]

I also like to say don’t Maintain it like a dummy

[@TwinbornMist]

I bought a used wrx aside from cosmetics the engine is really healthy since i bought it hasnt burned oil or lost any, like you said if drive normally they will be just fine and if you drive harder make sure you do your maintenance at the interval or earlier

[@1lesavage]

Ran 370 to the wheel for a year and a half. Just fine. I have 86k miles and im back to stock because im selling it. The number 1 way to keep your car from taking a shit is oil change ever 3,500 miles hands down.

[@nicolasmerritt3760]

Appreciate the content. New to the platform. Been slowly acquiring knowledge and parts. Sitting on performance mods until I’m done with cosmetics so I know that I’m doin the performance stuff the right way. Keep postin. I’ll be following. You got other media platforms you’re uploading to?

Seems like I am doing everything right so far. My 2014 wrx came with an aftermarket racing clutch, aftermarket rack & pinion, and I got an AEM Cold Air Intake (Carb certified) installed on there. ECU was flashed after install by ASE certified professionals. Right now focusing on body and suspension mods, but I will get a COBB accessport before I do anymore HP mods. Catless downpipes are illegal here so I would never get one. And lastly I get all my work done at a performance auto shop that's pretty reputable in my area. I've never had a car this fast before and I am focusing on making it feel more stable before I make it any more speedy at the moment.

[@TNATION22]

Thank you guys for the info 🧡 I just got a 2018 WRX base and I love the looks of the car and want it to last as long as possible. It is in fact, my baby 😂 I just want it to sound a little nicer at some point!

[@TurtieSanders]

Sup Boiz from Sault Ontario Canada, I appreciate this video so much! I've heard about doing most of the things you guys mentioned doing and I'm going to work on them for sure. I've had my 2015 Subaru WRX for 3 years now. There's only 1 mod I want to say that in my opinion is extremely important even if you wanna stay stock: RUN A MACH 2 GFB DEVERTER VALVE. I had a lot of boost lag, throttle response was terrible and biggest thing was the stock diverter you could blow through it with your lips. Get a new diverter valve. Also should mention, the boomba, is NOT reliable. I had a boomba, sounds cool but I had a lot of inconsistent idle. Swapped to a MACH 2 GFB Diverter, miles different. Even some exhaust pops with everything stock.

Just got a Premium Red 2020 WRX. It will be my daily driver. Just want to do a few minor modifications. Remote start, mud-flaps, paint protection, radar detector, interior camera, security system upgrade. AOS, cold air intake, full exhaust kit and nice tires for the summer. I’m not lovering the WRX because the roads are horrible where I live. Heard about Cobb tuning to stage 1 but I don’t want to void the warranty.

Depends on how much power you're pushing! In my opinion, especially in ohio where you get pretty cold winters, you're not going to see much benefit from 40w. It'll make cold starts much harder during the winter. But if that's what your tuner says.. 🤷‍♀️ idk maybe have that discussion with him.

You don't need one, but our cars are very sensitive to any change in the air intake. That's why we can't use random air filters. Technically I could be safe to run an aftermarket IC without a tune, but I absolutely doubt that the car wouldn't see a DAM drop or something like that. Plus, without a tune you wouldn't actually see any benefits other than a larger mass for less heat soak.
