Is it ok to put in a drop in K&N into an 09 WRX without gettin a tune for it. Also what if any are the benefits?

It's fine. The sensor will be able to meter the air with the stock box/K&N, so you can see a small increase in power. Basically makes room for other mods though.

Thanks ratfink, now I know K&N puts oil on their filtes, what about excess oil gettininto the inlet tube?

Just wipe it down, as long as it's not dripping wet you'll be fine. You should always wipe an oiled filter before install anyway.

Well I guess I'll ask a question here about my CAI. Does anybody have the Perrin CAI and feel like they've lost power up top? I'm not sure if it's the intake or just my butt dyno getting used to the car after 6 months but I feel like the car might be holding back a bit with the increased airflow... It still pulls pretty well and I hit 60 pretty quick I just feel like it takes forever to get through the last 1k or so rpm's now.. Maybe I'll have to run a test and put the stock airbox back on and see if I notice a difference.

I got a Perrin CAI and I noticed a BIG difference actually. I recommend it to anyone. Ive never been on a dyno, so cant help you there, sorry. But instantly after installing I noticed a difference and could feel the power. I also didnt have it tuned either at the point either, I read you mensioned you asked about tuning. I didnt tune mine till I bought my downpipe and Perrin TMIC. For awhile the stock ECU was adapting to the MAF readings so I was getting mad MPG, like anywhere from 26- 35mpg! NO JOKE.haha
