If I used an aftermarket air filter instead of OEM air filter, would it void the warranty? Anyone know, please let me know. Thank you

 

I am going to assume you are asking about the engine air filter. The answer is no if it is classed as an OEM replacement part. I have been using the Purolator A25585 filter in both of my 3G TL's and it works fine. Incidentally, the stock "Honda" filter for the TL is a good unit, though somewhat restrictive. It is a dual plain filter with an oil-wetted bottom section and a dry element top section.

 

How about a K&N filter on a 2007 TL-S?

I just ordered one. I don't think there will be any problem, but does anyone have any experience?

 

Pretty much the only way an air filter would void a warranty would be if th engine was able to ingest particles resulting in "engine damage". If you are remotely unsure or concerned with this issue on any given air filter - why purchase it...

Bottom line, somewhere within the air filters documentation it should state: "meets or exceeds manufacturers requirements" etc..

 

I just want to make sure and don't give a dealer an excuse to void my warranty.

 

The only time I've heard of the dealers hassling you, is if you have a K&N filter, and you over-oiled it, causing the MAF to get caked with oil. But in that case, they only voided the warranty on the MAF itself when it needed to get replaced because it was caked in oil.

 

Just switch it out before you go in.. lol

 

The '04 and '05 TL's do not have a MAF. Can't speak for rest of the 3G years.

 

Yeah sorry, I always interchange MAF and MAP sensors when I talk. They serve the same purpose. The 3G TL has a MAP sensor, located in the throttle body. I've heard of dealers voiding the warranty on the MAP sensor if it fails due to it getting gummed up with filter oil.

 

Yes they do (serve the same purpose). The one major difference between engines served by a MAP versus a MAF is this. Engines using a MAP sensor also make use of the speed density method of fuel metering. There are other sensors involved in this such as ambient temperature, throttle position, and oxygen sensors which along with the MAP sensor, allow the ECU to perform table lookups in order to arrive at the most precise parameters for fuel delivery and spark advance. In 1987, the Ford EEC-IV ECU was one of the best, if not the best, speed density ECUs made and saw fine use in the V8 Mustangs of the day. In 1989, Ford went with Mass Air in their EEC-V ECU.

Our TL's, of course, utilize speed density methodology.

 

If you are that concerned just swap it back on when you bring it in for service.
