K&N Air Filter

[btorocco]

I was speaking to my service manager today and he said that installing an air filter such as a K&N (which I've already done) will void the powertrain warranty. He went on with some babble (although he did admit the K&N is a great filter) about changing the air flow, blah blah blah. So I'll just have to re-install the OE filter when I bring the car in. Is there ANY chance this filter can actually do any harm? Say it ain't so.

My dealer says no issue unless the intake is affected by debris...

I also installed it... my kids like that it isn't a throw away and thus they think it is good for the environment... I can't seems to get them to understand that the oil bath it requires is a bigger impact that the paper it replaces... but what can you do...

also, come back with that:

8. Will using a K&N direct replacement filter void my factory warranty?

It is against federal law in the United States for a manufacturer to require the use of a specific brand of air or oil filter unless it provides a replacement air or oil filter, free of charge, under the terms of the vehicle warranty. For a more thorough discussion of this law known as the Magnuson-Moss Warranty Act, see our Vehicle Warranty Section of our Air Filter Facts page, and our Letter Regarding Vehicle Warranty and K&N Replacement Filters.

Thanks for the info, guys. I've never heard of an aftermarket af being a warranty issue. Sounds like this particular service manager may be a little difficult to deal with. I'll ask another Hyundai dealer and see what they say.

What you can do is what you've done. Try to give them the TRUTH as best you can. The public schools are brainwashing our kids. Makes me wanna puke, but this is a discussion for another time and place.

Hyundai or any manufacturer is NOT requiring the use of a specific brand. You can use just about any brand, Fram, Purolator, etc, but what that dealer was saying IMO, is that the K&N Air Filter allows more air, and more dirt through, so it could cause problems, and Hyundai will not warranty those problems. I.E. Yes, K&N allows more airflow but that more airflow also allows more dirt.

I distinctly recall the dealer saying something about changes in air flow affecting this that or the other thing. Nothing about more dirt. Besides, didn't K&N become famous for trapping more, not less, dirt? If what you say is true I'll get rid of it tomorrow.

The reason why K&N is such a great company is cause they can allow a lot of air flow while filtering the air as much as possible....

with your logic might as well not have a filter at all and leave it wide open.

@OP: The dealer is smoking crack. I have an CAI (cold air intake), front mount, and full exhaust system. I took my car in many times for transmission issues, electrical, and what I thought was "knocking" and my dealership gave me no problems and never even mentioned my Modifications.

Even if for some crazy reason the intake can effect your car in a negative way, lets say you didn't clean it properly (k&n is reusable) the dealer would first have to show you proof that it was the intake itself which caused the problem.

This is exactly correct. That K&N filters allowm more dirt into an engine is pure Urban Legend. They are great. I have used them for decades and have never had any issues. I generally re-oiled them every 30-50K miles and they truly were the "last air filter" I bought for those vehicles.

Agreed.

I recently bought a 2015 GC 3.8L and one of my questions to them was will a CAI ruin my warranty, they said no the only mods that will have to directly effect the GDi. Thats my experience.

 

[LandoAWD]

You cannot "void" a warranty. You can be denied coverage based on the causation of failure, however.

A CAI sucks up water you were silly enough to submerge it in? Denied. Your left-rear shock goes out after a CAI install? Covered.

That said, this should be common knowledge before talking mods, and this is an OLD thread...

I read BS online all the time how a high flow filter HAS to let in more dirt. What people don't understand, is that the extra flow is from the extra surface area due to the fact that a pleated flat paper filter has less surface area than a cone shaped more radically pleated oiled cloth filter. It lets in more air over a larger area.

I also see where people put a car on a dyno and "prove" there's a loss of power at peak. The advantage of pod filters isn't so much at peak power, but the power band is raised in the low and mid-RPM range resulting in more area under the curve and a broader increase in power. Area under the torque curve means a lot more to performance than losing 1-2 HP at peak.

QWT. I recently replaced my OEM with a K&N, LIFETIME/MILLION MILES guarantee. And they even include an 800 number if ANY service dealer tries to claim it needs to be "replaced" (as in, rip-off small business BS).

Further, I recently posted that my GC recorded it's highest-to-date, mpg reading on the same trip that I've recorded 3 times. With the K&N intake filter being the ONLY thing changed between recordings, a 1.5-2mpg increase in mpg was a result (highway, approx. 400 round trip).

And lastly, I'll say this; if the reading/sampling of mpg was to be proven to be, in reality, a .25-1mpg increase? I'd buy this filter all day long. After all, it's barely the cost of 2.2 filter purchases.
