i've had my drop-ins in for about 2 months now and not a problem what so ever. . .something wrong with that dudes Z. . .oh, and the guy shouldn't have had to oil the filters because they already come pre-oiled in a plastic bag. . .

i use to have k&n filters, the oil caused my MAF sensor to fail 2 times. the dealer said that the oil made it go bad. that the same style without the oil would be better.

Try pm'ing A.H. or infinite for more info, they have before and after dyno sheets to prove it also look and search for threads around here, tons of people have em. Injen's CAI has long tubes that positions the filters directly behind the grill so it's getting cold outside air compared to the K&Ns drop in filter, which pulls hot air from the engine bay instead.
Colder air = more power.
Colder air = more power.
You must be referring to the K&N Typhoon Air Intake kit not the drop-ins... The drop-ins pull air from the same place the Injens do.

I used to go to Quaker on my streetbike, Wednesdays, but that got old. I just purchased this car last week, so I'm sure i'll find some time to make it out.

I had K&N drop ins in my '07 Z from about 5,000 miles to 15,000 when my servive engine soon light went on. The dealer found my cats and O2 sensors were bad. Bottom line, they replaced them under warranty but replaced the K&N's with OEM filters. They suspect the filters caused it. Only thing it could have been was excess oil from the filters. I didn't oil them when I installed them. I'm hesitant to put them back in now.

I suspect your cats would have failed anyway, it was just convenient for Nissan to blame the filters!!! If your car was completely stock at the time of the failure, they most likely would have blamed global warming...

If you bought the filters NEW IN THE BOX, then K&N pre-oiled them to their specifications. If you clean them on your own when you feel they are sufficiently dirty, THEN you re-oil them.
If you got them NEW, do NOT attempt to ADD any MORE oil!!! That would be a PROBLEM!!!

As I said a in post #30 above I didn't oil them because I knew they were pre-oiled and I still had an apparent problem which seems to be have been caused by the filters. They could have over oiled them at the factory.

I have a question for you guys who have the K&N filters. Did you notice any difference between them and the stock filters? (power/sound etc.) or just did it for the convenience of not having to buy filters again (just wash and re-oil)?
I used K&N on my old car (98 eclipse) without an issue but it had an AEM cold air intake that was all the way at the bottom, so it would have been kind of hard to suck up oil, since it had a long ways up to travel to the engine.
The Z there isn't much room so i could see how it would be easier to have issues if by chance there's too much oil in the filter.....just a bit worried after reading all the stories.....
Also price is an issue, if there was no real difference I'd probably go for the stock ones if all else is the same....
Thanks!

K&N oil filters are actually really shitty.. Lets take oil and put it on something that is supposed to breath.... Its almost like trying to breathe when your are sick and stuffed up doesn't work to well huh? Your best bet is a dry filter. I learned from past experience of having a K&N filter. I would consider buying them oiling it lightly then driving for a week or two take the Maf and clean it. But I would rather find a nice dry filter like hks or something along those lines.
