Default K&N in the mail

Look what just arrived:



So, if I install this and remove the rubber stopper under the accelerator, that's like +40hp, right??

Mr Big,

Probably don't need to, but you can just in case and it won't hurt anything

You can reset it by

a.) removing the battery cable for a few minutes
b.) pulling the ECU fuse in your fuse box located (in the 4) in the engine compartment near the windshield, passenger side

Photo courtsey bananags



And a thread with a decent explanation click here

If you flip open your fuse box and look at the inside of the lid, it will have a map to tell you what each fuse does.

If you have a non-nav car, you will lose your radio settings and your personalized seat / mirror preferences.

To be quite honest, I did not feel any gain what so ever in performance when I switched out the oem and put in the K&N. I believe its nothing more than marketing hype on K&N's part. The only advantage to the K&N is that you can clean it and re-use it. No more no less. BTW, my gas milage was the same with oem vs K&N.

i just got the k&n drop in for its warranty.
be moderate on the oiling, you can clean/reuse it. i doubt there's really any hp gain, but it breathes more air (maybe not that much more than oem though); which should be good for the car, right?

Default Airflow problems on GS 430. Lag, Hesitation

I have installed a k&n air filter in my 2001 gs430. 1 month later i started experiencing problems. When I push the gas under low RPM, the car stalls and RPMS drop, then I'll push the gas again harder, and the car would drive. problem got worse. When my mechanic checked it out, the computer showed that it was the maf. He remove the K&N filter, and it looked like playdough. Very dirty and greasy. I never had that problem before. The ECU light never went on.

I see here that many people complain about the same problem with their GS430S. I dont know what the problem is exactly. Can it be the MAF? or Cleaning the fuel injectors? or the TPS? or throttle body?

Any feedback would help a lot. Thank You.
