You might get a little more power w/ it removed...until the MAF quickly learns to adjust for the extra FLOW, unless maybe you're always at WOT...and it's nice insurance to have in the event you have an oiled filter installed.

Nope, still using Toyota paper filters. Eh, I might take it off, but I don't think I'll have the time to since I start school again soon.

If you pop the lid on the intake what is the screen like filter at the top part of the air box. Is this what everyone is talking about as the secondary filter??

Anyway, from what I can gather from reading, it seems that removing it ("the carbon trap") does not really increase perfomance to any worth while degree. BTW, I never had a problem with a K&N filter in all the years I have used one. :smuile: The one problem I did have with a MAF was on a car that didn't even have a K&N in it and was running the stock filter. If I had a K&N installed, would this now have been blamed on it? We all have to be careful not to jump to false conclusions. Also, even Toyota a sells oiled, K&N type filters... it's called a TRD filter so even Toyota has no problem with them. Some very interesting info. Be shure to watch all the videos. http://www.knfilters.com/MAF/massair.htm Last edited by RedRide; 08-27-2009 at 02:05 PM. |

BTW, I never had a problem with any of my K&N filters and CAI systems, but I've seen lots of dirty MAF meters, oiled & paper filters alike. So I don't need to be careful, I've seen actual proof of dirty MAF meters and confirmed datastream info (calculated engine loads, before and after a cleaning) Oh, and in a recent magazine (MotorAge?...can't really remember) they had an article on MAF meters and oiled elements. I noticed their claim that many automakers will not honor warranties if oiled filter is installed. |

We all know how some dealers tend to not want to honor warrenties and look for excuses. There has never been a doumented case where an oiled filter caused a MAFS to fail. The worst case senerio can be where a filter is over oiled. Even then it can be cleaned. A dirty MAFS does not equel a "failed" MAFS. A MAF can fail for various reasons and just because an oiled filter is installed, does no mean the filter is at fault. |

Never said MAF sensors were *ruined* with paper or oiled filters installed, said I've seen lots of dirty sensors. |
