K&N that speaks for itself
Perfect fit just what I needed for my project car. And has that nice sound to it now.

Good filter... measure CORRECTLY
Make sure you measure the diameter of the hose/air intake you intend to install the filter on. THEN match it to theINSIDE diameter of the filter flange you order. I know, sounds like a no brainer. But I managed to screw it up the firstfilter I ordered. Otherwise the filter works fine.....

Wow!!!
well i got it on time and it installed right away. No Problems. Works great and has been for months now. Would suggest before you select any K&N air filter that it will fit your car or truck. I took a long time picking this one out. Was shipped and sold by Amazon. Thank You!!!

Exactly what I wanted
This thing works great. It came to me in perfect condition and fit the adapter I bought so that I could use my stock intake setup. My fuel efficiency is about the same but the sound my car makes at wide open throttle is wonderful. When the car is idling, you can hear the intake sucking in air, which really makes me doubt the stock airbox. Great purchase. I have been using it for close to 20k miles.

Great durability
Dimensions are exactly as described and this filter held up in my turbo application where the cheaper Chinese made filters fell apart.
