K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty

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!
