So.... this have been referenced a lot but, i just bought a 2015 evo FE and my service department said any mods (including intake) would void my warranty. my questions is, if i revert it back to stock god forbid if i need to warranty it. if its undamaged is there anyway possible way they could tell it was there thus voiding my warranty? docent seem like they could but i want to make sure theres no way. ill probably eventually void the warranty when i hit around 25k and then its bolt ons galore, but i can't stand the look and how restrictive the stock intake system is. its terrible!

 

depends on the intake. Most require a retune, as the pipe diameter is greater than stock, making the mass airflow sensor read incorrectly. If you get something like the K&N intake, which uses the same diameter pipe (pretty much), you won't have to retune it. As for warranty, I'd imagine taking it off and putting the stock one on shouldn't be a problem.

 

Only if you get the car tuned could they tell. However, I wouldn't advise running an intake without a tune.

I've had a ton of warranty work done after being heavily modified, and at several different dealerships.

I wouldn't worry about it, just run an intake and get a tune. Return it to stock if you are really worried, they almost certainly wouldn't check the tune count. I don't think I've ever heard of anyone getting warranty voided because of that.

 

Your stock intake isn't restrictive really, if you want a small jump in smoothness just get the drop in Cosworth panel filter. That needed me around 15hp without a tune. I know this because I got it baseline dyno'd with just that and it was putting down around 240 stock instead of around 225 which is what is normal and expected.

Also be very careful modifying the FE without getting tuned as it has a factory tune that isn't the safest to run mods against without a proper protune.

 

Don't spread that horses**t. Enough reputable tuners have said that its fine.

 

And I know a reputable tuner that believe this is cause enough for concern to give away a free retune to any FE owners

I'm not bagging on the FE I think they are fantastic, but I don't think it is a bad idea to share corroborated information with people that own them so they can make up their own minds.

If I were an FE owner I would 100% want to know this before I started adding parts to the car.

"Don't shoot the messenger"

 

What were your results before, and then after your filter being dropped in? "Expecting" 225 whp depends entirely on the dyno, and hell, even on the same dyno there can be 15whp variance between different stock Evo's no problem.

I do agree though, the panel filter is fine for a cheap first mod.

 

I do agree I didn't have a true true baseline, however the shop I went to, Kozmic, indicated that based on their countless dyno's of stock vehicles, I was putting around 10-15 hp more due to the filter all other factors being equal.

I did notice a much smoother powerband and it eliminated a minor stumble I had around 6200 on the stock tune so it was noticeable.

I also chose the Cosworth because it wasn't a filter you had to oil as I was concerned about fouling up the MAF sensor.

 

If you are dead set on getting an intake then you could probably run one that retains the stock MAF housing. That should be fairly safe w/o a tune.

Also, the stock intake isn't restrictive unless you bolt up a bigger turbo. It is just fine for a stock turbo. Same with the intercooler. Now exhaust on the other hand, that really should be your first mod on principal. Forget the intake. Get a drop in filter, cat back, and enjoy.

 

The cat is the part that is really restrictive. Id do a drop in, test pipe, 3 port, tune and cat back.

 

He doesn't want to void his warranty...so that pretty much leaves out a tune, which then leaves out a 3-port and test pipe.

Even if he used an AP he could possibly be denied warranty work.

 

Has anyone ever definitively confirmed that there is a "tune count"?

 

Thanks I'll probably persue the panel filter route, or maybe even just go for
It and get a tune, hope nothing happens and if it does then try to revert to stock for warranty purposes.

 

depends on the dealership..ive heard of people with just a cat back being denied. a lot of it is attitude and how you act as well towards everyone.

 

I don't believe this. Please post a link to someone having warranty work denied due to just a catback.
