K&N Air filter questions

[RedRide]

I have be using K&N air filters for years with absoluly no problems.
One benifit of a K&N is they tend to "open up" the top end a bit.
Making an engine breathe easier can only be a good thing.

Cleaning and re-oiling could not be simpler, just about idiot proof but, evidently some do manage to screw it up.

.......if you could improve MPG by dropping in a different filter, Toyota would have done it already..........

Well, actually, Toyota does sell and install a "K&N type filter. Toyota calls it a "high performance" TRD filter and it is made exactly like a K&N for a ridiculous price.

And if you read the fine print, and didn't let an authorized Toyota/Scion dealer do the install of their TRD HP part [don't know their view on K&N]...any problems that might occur can void warranty on part and possibly vehicle warranty.

NO..... a warranty can not be voided by using a Toyota filter.

BTW, once I got a TRD exhaust for my Celica and had the dealer insalled it as then it would be covered under the bumper to bumper warranty which still had 2 1/2 years left on it at that point.

The service manage then asked me if I wanted a TRD air filter also.
When I told him I already had a K&N filter installed he said OK then.

Wrong. Care to scroll down to the warranty claim on TRD parts NOT installed by the authorized Toyota/Scion dealer?

Guess it could all depend on the dealer and how serious they want to be about it...

Well yeah, That's why I said I let the dealer install the TRD exhaust
since I had well over 12 months/ 12k miles left on the Celica's warranty it piggy backed on that.
Othewise, I would only get 12 months/12k miles if i installed it myself.

They don't give you less warrany it you install it yourself. They give you more warranty if the dealer installs it providing you still have warranty (over 12 months/12k miles) left on the car to begin with.

This has been standard warranty practice for TRD parts for years.

The difference in warranty coverage is dependant on who installed the TRD part; authorized dealer installed, no issues with part or vehicle warranty, but as my TRD link stated, non-authorized installer of TRD part can void warranty of part, or vehicle, or both.

I used to run K&N filters until I started seeing UOA results come back with dramatically higher Silicon counts. 1stToyota is right about the amount of dirt making it through the K&N filters compared to the OEM paper one. When it comes down to it, I'd rather pay for the disposable filter than have a bunch of sand in my engine.

I'm sorry but, I fail to see in your link where is says a non TRD part can void a warranty.
Fist off, that woul be illegal (at least in the US) unless Toyota can prove that it caused a particular problem that you claim is a warranty issue.
The same would be true for any after market part.

As far as a K&N filter, since Toyota also sells the exact same kind of filter, they can't legally claim it caused a problem.
