YUUUUUUUUP - received the new air filter for my 2012 Challenger Wednesday afternoon, was driving Thursday with it installed. WOW- made quite the difference when lighting it up at the start and  while cruising along at 60... hit the pedal and you can truly feel the difference. Also, added a change in sound as it now sounds more throaty....I am a happy customer

Shipped quickly. Dropped right in. Seems to be working as it should. Looks like great quality and I got a free sticker as well. Would buy again!

This the second K&N air filter I've bought. Leon (The Motorman) Kaplan recommends them very highly, that's where I first heard of K&N many years ago. Love the performance and ease of installation.
