They're return policy states that they do not accept returns on Mass air flow sensors or anything electrical.

Then go ahead and clean it. A MAF cleaner may only be 10 bucks, I have heard other stuff works too.

I was worried for nothing, they gave me a return authorization number. No big deal just have to send it back.

i would put a K&N anyway, just remove the oils prior to installing, I did that and have yet to have an issue with it. MAS is good and sound and pick up is great....No different than using those $300+ cone filter intakes since they dont use oil either. Probably the vacum pressure in the intake and the restrictive flow of the stock filter is causing this.

If the intake tube is plastic, it could be flexing during full boost on the vacum end of the intake tube.

Hi,

If you're using a K&N or other oiled filter media Filter w/o the Oil, you might as well not use any filter at all. That is because they have much biiger holes in them than the OEM paper filter and require the Oil to trap dirt particles.

All the evidence I have seen (ISO 5011 testing) shows that K&N cannot substantiate any of the claims they make. Their dyno charts may show 1-3HP increase, but for a new filter. 3k mi. later, according to ISO 5011 results, that same dyno would yield a chart showing performance to be inferior to the OEM paper filter. They a car go faster about as much as an STP sticker in the window...

Happy Motoring!... Jim'99

Sorry you had to say all that, cause i dont care. I dont have the KN for performance purposes, Purely for the intake noise and the little bit more ease i get from a stop to go.

Saying that i might as well not use a filter is the dumbest thing I've ever heard. If i didnt have a K&N or any filter at all, Very large particles of dust and other debris would be allowed to get into the intake and heads. It really bugs me when i hear stuff like that. The proof that my filter catches small, fine dust is in the filter, When I clean it out, I see a variety of dust from very fine to large. While i know that its possible for some very very fine dust to get past the filter...Im confident that it would only be the very fine stuff that wouldnt have any effect on my engine.

If you want to refeut that, then introduce me to someone that used a K&N and a large debris got past the filter and caused major internal damage to the heads...If you cant, then i dont care what you have to say one the subject of Air Filters and risk of debris getting past them.

Just when the threads were getting boring.... Hey Rail I'll get the popcorn if you save the seats for me and Griz....

My K & N didn't let large enough debri through to mess up the internals of the engine BUT it did let enough oil and debri through to ruin my MAF.

I'm glad you typed this, I'm tired of this worn out statement, I have run one in my vehicles for years without incident.

Hi,

As for the last one, look up what an ISO 5011 test is - irrefutable, repeatable, non-anecdotal, evidence. 'Course, I wouldn't expect you to accept that...
