Decided it was time to install my cone air filter I've had sitting on my shelf since I wrecked my Toyota and took it from it. Its a 3" Diameter K&N filter. I discovered that an older Toyota Celica / Previa adapter fits PERFECT. Bolt holes line up, and the square opening in the adapter is the same dimensions as the flapper style MAF's opening. If you're have a flapper style MAF, get an adpater for an older Celica/Previa.
Then it was time to wedge that cone filter in. I ended flipping the MAF upside down, and wedging the filter between the fender and the MAF. It fits snuggly.
I don't think I have much more power, but the throttle response is better. Plus, it sounds great.
