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.

Last year I removed my intake silencer on my 99 4runner(5vzfe)and replaced it with a straight pipe and did a deck plate mod and got a few mpg's out of it with a little more pop and sound. Today I dropped in the K&N as I was going through cheap filters every 6-8k with the open box and wanted the ability to just clean it. Didn't expect a lot out of it in the HP department but WOW. I should have done this a year ago. This, with the pipe intake, feels like easily 10+ hp added. Sounds like a ton of air is moving in the pipe now. Very happy with this one. I would recommend it.

I bought this air filter from my work yesterday. I drive a 2000 Toyota 4runner 3.4. Of course everyone knows that vehicle drinks gas like crazy. Especially being 15 years old. It got to the point where I was spending $120 a week on gas. So I used seafoam cleaner and bought the air filter. The price got me but as soon as I put it in and drove it for a bit I instantly noticed a difference. From feeling the gas sucking horribly while stepping on the gas pedal with my old filter to actually feeling the difference with the K&N air filter was astonishing. After driving to work and back usually I'd kill almost a quarter tank. But since I put the filter in I can tell that my intake air system is breathing a lot better and the needle barely dropped. Highly recommend this air filter. Pricey but you really do get what you pay for. Extremely satisfied.
