Default K&N void Warranty

I have a 2016 STi. I have always gotten K & N panel filters for my cars. I wanted to know if a panel filter will void my warranty? Does anyone know? Thanks in advance.

Can't void, but if there is a failure they can attribute to it, they will deny that claim.

I don't know how sensitive the MAF sensors are with the new STi but on the GR an aftermarket air filter would lean out the A/F ratio by 0.5

I've been using the HKS Super Hybrid panel filter, that's the only one that is safe (by logging) at least for my 2013 sti. The only reason I got it is its easy to replace the filter as the filter media is removable from the panel filter housing. My dealership suck balls so I avoid them as much as possible, 25 bucks for an oem oil filter .... and the sort.

Wow $25! I use the OE filters and change them often, but they cost me like $11 out the door. I guess the newer cars have fancier filters or that dealership really is hungry.

I don't know if a K&N filter would cause warranty issues, but I could see it happening. Oil leeches off filter element, coats MAF, causes lean run condition and it's so long and thanks for all the fish. Subaru dealerships are really inconsistent with how they handle warranty issues. If you're worried I'd say skip it.

It won't void your warranty but will void your motor...

I like those filters for my vehicles as well but better to just leave it oem on this car, too risky.

Subaru warranty for the engine is basically useless. Even if left 100% stock, they will just say that you "abused" the car should your engine fail (unless its some sort of well known QC issue) and deny your claim. Better choice is to use whatever intake you want, get an accessport, and tune accordingly. You'll make your engines safer by getting the garbage tune off of it, and you'll enjoy the car even more. Just be smart about it, don't push the limits in the tune, drive appropriately, and monitor the tune occasionally (especially if doing any hard driving).

I personally had an engine rebuilt under warranty with a k&n panel filter installed. SOA personally told me they didn't care about the K&N filter. They also didn't care about the AOS or aftermarket catback.

It may/may not void your warranty. What I mean is that if there is an issue, then they will deny coverage due to having an after market air filter. Warranty guidelines are very strict with that. I think stuff like this is even covered in the manual. I the past generations sti, GR's were reporting some leaner conditions using after market filters w/o the correct software on the car. The stock tune is already lean enough to meet emissions standards. Lean conditions can lead to a laundry list of problems.

I would not recommend installing one of those filters. A $25 dollar filter could leave you with a much large bill if something were to happen. Its not worth the risk, especially if warranty is denied because of it. Now if you want to mod the car correctly then there are plenty of options for intake systems and tunes. Just know that once you mod the car and change the tune on it, warranty is basically out of the question.
