Yeah, the car feels like it inhales a little easier now, but I'm still a little worried about the oiling piece when cleaning. Don't want to create MAF issues for myself...

On my Yaris now, I just have a drop in K&N filter. No power difference felt until I removed the carbon trap. Felt a tad bit more responsive, and my mpg went up.

On my FR-S, I have a K&N drop in filter. No power difference by itself. Once I tuned the engine with an OFT, picked up quite a bit of power/torque, especially around the torque dip area of the FR-S.

Got an Injen SRI for the FR-S. Car drove like sh!t. Would bog down if you WOT from a standstill. Car felt like it lost quite a bit of power too. Intake temps were 10+ degrees higher. Removed it after a week and sold the Injen, and went back to the OEM intake with the K&N.

Did you unplug the battery and reset the ECU after installing the K&N? Call me crazy, K&N doesn't say anything about it, but I didn't feel an improvement until sometime after having installed the K&N and then needing to disconnect the battery for something unrelated. I could be crediting the K&N for improvement that simply came from the ECU reset. Not ruling that out.
