Great product. Took about 10 minutes to install. The AAG team kept me updated on the status of my order from start to finish. I would order again!

Ive owned a few vehicles and this replacement re-cleanable K&N filter is top notch for its price. Out of warranty service charges 10-20$ for a cotton disposable air filter at each oil change so this type of upgrade is/should be a no brainer for any vehicle. I give it an A just for this reason alone. It pays for itself. =) The only reason it doesn't get a perfect score is due to the fact that for (*Some vehicles), one must struggle a bit to get it to fit nice and snug without bending or creasing it in the factory air box.. This is an issue K&N needs to put attention to. Especially with customers stating this fact for them to see.
