Installation of this filter was very easy. It fit very well and since my 2009 DODGE CHALLENGER is SUPERCHARGED it does allow my 5.7 Ltr Hemi to breath better but that may be just my positive thinking. It does however seem to respond just a tad quicker and I'll love the lifetime warranty and cleaning the filter every 50,000 miles even I know I'll probably check it more often and clean as needed. I'd recommend this K&N filter to anyone!

This is my third K&N air filter but the first for a car. My other two filter purchases were for motorcycles, the first was bought around 1990 and lasted over ten years. The second m/c air filter was purchased for my current m/c, around 2007 and is still working great. The recent K&N air filter purchased for my car installed perfectly, just like the OEM filter. I have not taken any trips yet, so I haven't been able to determine any difference in gas mileage. Just driving around town, the car appears to respond slightly better than before on acceleration. The cost of this filter is about 3 times that of the paper element filter for my vehicle. Since the K&N filters can be cleaned and reused, this filter will pay for itself in about two years. Yes, I am quite happy with this purchase. For years, I have recommended K&N air filters for motorcycles and will now include automobiles.
