K&N 57 Series FIPK Air Intake (50-State Legal) Reviews

Great CARB legal option for CA Cars

Reviewed By Jeffrey D (Newark, CA) Reviewed for a 2007 Chevy HHR —7/12/2013 9:18 PM

I recently had to swap out the air cleaner system on my car since CARB decided to change the rating for the GM Performance intake. The K&N system is CARB legal and was a breeze to install. It also is a lot quieter than the system it replaced. I don't have a constant drone at highway cruising speed and at stop lights I had to check if the engine was running after I first installed it. But stomp on the skinny pedal and it lets you know it's there and gives the engine some extra grunt.

Hypertech Max Energy Programmer Reviews

Genuinely Pleased

Reviewed By William B (HUNTINGTON BEACH, CA) Reviewed for a 2007 Chevy HHR —9/21/2012 12:23 AM

I did some homework and decided this was the reprogrammer for me. AutoAnything had the best price so I took the plunge. Installed the program and am totally happy with the results. My "butt dyno" feels the difference. It won't peel the rubber off the tires but the performance change is there. MPG has gotten somewhat better too. All in all I'm a happy camper and would recommend this product.
