I was very tempted to but a K&N drop in air filter, however upon reading loads of reviews and info I have been slightly put off by the fact that the oil sometimes fouls up the MAF sensor (not a good idea!!).
I noticed that there is a dry Pipercross drop in filter and I was wondering if anyone has tried it or has any comments?
I realise that the gains in MPG or performance will be minimal, however as long as it performs better than stock any advantages count yeah?? I realise that this may get into the debate again about whether K&N lets more dirt in etc, however what I really wanted to know was, is the Pipercross any good or does anyone have any good drop in filters that are better than stock other than the two mentioned?
I do not want to get into changing the stock box for an aftermarket induction kit just yet so just drop in ideas for now
Thanks in advance.

That's only if you're idiotic enough to over oil the K&N filter.
K&N won't let in more dirt if you oil it properly.
Sorry brother, a properly oiled K&N still does not compare (filtration wise) to a good paper(synthetic media) filter. I have never heard of this filter though. The full race RX-8's went back to factory OEM filters due to the sand that was getting into the oil pans.
"Clean is the new cool, so letís keep it that way."
Perrin according to test demonstrated on youtube filters better then OEM and you gain more power with it then with K&N....but i am suspicious of how long it cleans better then others. In time particles find their way through foam and it will not be as affective.
HKS foam filter is the worst in cleaning and does not flow better then K&N

K&N drop in filter...no need to molest two cars.
as usual, it is only a test and a flawed one at that
a real test needs to be conducted in a lab under contolled conditions, driving a car on the road means uncontrolled conditions. There's no guarantee that the vehicle encountered the same dirt amounts in the air, particle sizes, etc.
also as usual, it's an easy out to point to this flawed test and claim it's the end-all answer for life. Fail ...

I'm not a fan of K&N filters because even though they flow well, they allow much more dirt into the intake tract even than other "high performance" filters.
I've used aFe short ram intakes with great performance results, verified by me through back to back, same day/same conditions testing. They flow almost as well as K&N and filter much closer to stock filter performance -- IF you clean the filter frequently.
That experience makes me wonder why no one here thinks much of the aFe (Takeda) intake. In my experience they make quality stuff that works well.

This discussion is about the K&N panel filter for the OEM air box which is a cold air intake. Not the K&N Typhoon Kit.
