OMG MY K&N FILTER!!!

[Yaribhini]

Interesting that almost everybody missed the point that I tried to make and that is not that the K&N flows less than paper media, it is that it does so at the cost of filtration. A K&N let's more in which constitutes a dirtier motor and throttle body. I'd love to hear the arguments for needing more airflow for this 100hp air pump. Please don't kid yourself into thinking that the K&N is giving you better results. The only think that it's doing is making your motor and throttle dirtier.

Chino,
I assume you have your Yaris on the track often? That K&N filter must have you blowing by all the Porsche's and BMW's!?

C'mon guys, stock paper media is where it's at with this Yaris. That's a "no brainer."

Is that what the stock Denso filter is made out of? I thought it was a recycled egg carton.

It was too wierd looking for me so I went with the Beck/Arnley paper filter and got impressed, real quick!

if K&N is sooo bad for your car then why do so many people still buy them? and are you guys really fighting over this.

You are actually wrong... Paper filters let very fine dust right through that coats the inside of the intake tube and can easily be seen when replacing the filter. An oiled media on the other hand catches all that fine dust and traps it. The inside of the intake tube on my Tacoma looked like it was removed from a brand new truck, and that was after 50,000 miles without cleaning the K&N. Trust me, they work, even in harsh conditions...

As for the MAF, I have personally over oiled a K&N filter and caused a CEL. But cleaning the MAF is SIMPLE (using CRC MAF cleaner, don't EVER touch the element with a q-tip) and disconnecting the battery resets the light. No harm done.

Compared to a stock paper filter, K&N's are better in every way...

It's an approved cleaning method on Identifix, unless someone isn't born with dexterity and nerve endings, and is real sloppy.

Paper doesn't invite gunk buildup on the MAF quite as well, causing a 10-20hp loss at the wheels instead of about 1hp gain at the wheels, if you're lucky.
