Yeah Hano, the oil from the aftermarket filters seems to affect the Bosch MAF more so than the Hitachi ones - u got the Bocsh one yeah?
Its more of a problem when u clean the filter and re-oil u self coz a lot of the guys get carried away and soak the thing in too much lub

Not really a prob if u using the filter straight out of the box though coz the factory ussually puts just rite amount of lub on

Personally i think there isnt much of a increase in HP/Torque with the aftermarket filters, and a more of a " i drove for a million miles " thing on the same filter, where did i see that add? - in other words its a longer lasting filter, do u really wont a filter to last a trip to the moon and back?

I found when i ran mine, just b4 the MAF died i was getting 'very' ordinary mileage from a stock car - not to mention the car felt just like a V6 and the thing wouldnt f****n rev at all!

 

Hano - a quick search on Audiworld will provide some information on this..... I installed a K&N in my '02 A4 a couple years back and it killed the MAF in less than a month.

To me its not worth the trouble for the little or no performance gains.

 

so then do you recommend just getting a oem air filter? because i've got the k&n in my s4 right now. should i take it out and replace it?

 

i dont know..i ahve k & n.. i havent heard anything bad..nor had anything bad in that regard. From what i always read just do a k&n drop in and your set.

 

see that's what i've read too. which is why i got the k&n drop in. i'm so confused....

 

i wouldnt worry about it.. im sure its fine.. just check it every now and then

 

It would be interesting to get some feed back from the guys who have the Hitachi MAF and K&N panel filter?
If it affects them as bad as the Bosch MAF? - or does it just make the Bosch MAF die quicker?

 

i have a bosch maf along with the kn drop in.. no problems with that.

 

i'll be switching to hitachi MAF fairly soon when i purchase my fueling kit from vast performance. i'll let you know how the hitachi MAF and the k&n go together. unless someone beats me to the punch

 

Thanx guys
The only reason i went back to the stock panel filter was coz i thought for the sake of a few Hp i'm not goin to risk the warranty on the new MAF
