i just recently purchased my 07 HR with only 5k miles it now has 9k as well as a 5 yr pt warranty. ha im still thinking of upgrading certain things like exhaust and cat, i heard its best to keep the stock intake if its still normally aspirated. Just wanted to know if anybody has any cool facts about the HR or any suggestions for street/performance upgrades...thanx

 

There are sections within the site where you can look for reviews/parts/and sections dedicated to the HR motor. Please use the search functionality and post questions that require specific answers.

The stock air box is the most efficent of the intakes. Most for the HR are strictly for looks/sound. Most with HRs, just add in a K&N filter to the stock box.
