Great, big noticeable difference. Increased MPG on highway and car has some go.

This product definitely performs as advertised. I could feel the difference with no lag on the pedal or when shifting gears. I plan on buying another for my second car.

After installing the filter, I could definitely tell that my car shifted better. It's a manual transmission and there is no more hesitation between gears. Do yourself a favor and buy the filter.

Absolutely amazing. I noticed right away. I would tap my accelerator in neutral and I had little to no engine response. As if the car had to think about it. I did the same thing after installing this filter and the car effortlessly took a breath. Very nice. I also saw noticible gaines in torque in 2nd and 3rd. My Rallye went from fun to a riot!

Car was less than one year old when I purchased the K&N filter. I noticed the filter gave my car a boost of power from a dead stop and shifted more smoothly getting on the highway, along with a few extra miles per gallon. I will have one in all my future cars and it's worth the extra you pay because you will never have to buy another one, just clean it every 50,000 miles. Drop what you are doing and order one!

Worked great! Took apart the air filter housing and fit like a glove. Was delivered much faster than expected as well. Would recommend and have recommended to friends and family.
