Smoother performance.

Throttle seems to be more responsive and the install is like an OEM paper filter. Just keep your re-oiling to a light spray and I don't foresee any issues with the MAF sensors. This is just one part of a revival of my 97 4runner. Engine clean, new sparks and cables plus fuel filter cleaning.

So far so good. The instructions were a little general as to why the added plastic bracket had to be used and could have used some text to describe what was supposed to line up. Once I figured it out, the filter was properly seated. There is a noticeable increase in power from my 4runner's V-6 and mileage has gone up by about 21 miles per tankful (or about 8) I am going on a long road trip and will have a better feel for mileage increase after that. It typically gets 24 MPG freeway. I expect to recoup my cost for the filter in about 6000 miles.
