Night and Day I have a 1997 Land Rover Defender 90 and replaced the old dirty factory filter with a new KN filter and it works fantastic. Not only does the motor sound throatier, but the truck really breathes better pulling hills on the highway and comes off the line from a stop with a lot less effort. When I have been 4-Wheeling, I notice very little lag at high elevations and can now tap the gas pedal to get over obstacles much more easily.

Thank you for a superior product, I should have install a KN filter years ago.

I bought these for my 2015 Nissan 370Z Sport Model. Installed them last month and have been really pleased with their performance. Throttle response has been much better, smoother and more predictable. Engine doesn't seem to be straining and I even saw an increase in gas mileage. Not much, maybe 3 mpg's, but it's better than what it was. Thanks K&N, I'll be back for more of your great products.

Just installed today on my 2008 Nissan Maxima 3.5 SE. Definitely worth the investment. Instructions were easy to follow. Performance: Difference felt once at 2500 RPMs. Quiet on idle but once the CVT is above 3000, you really hear it open up Nice deep growl to it along with a quick response to acceleration Tiptronic shifting keeps the deep growl going as well . It is approved for my state, but keep in mind this isnt CARB exempt. Go 63 series if your state allows it. Worth the extra $$. Thank you K&N!
