Have a hhr 2.4 lt and an air raid filter and box no other parts I like to do one thing see what I get and move to the next part .took a lot of slop out of the pedal added a nice crisp feeling to the throttle response .very easy install and instant results ! . A stock mass flow sensor cost about 75.00 dollars new and will not give you the added benefits of this reprogramed stock sensor.

Was fairly easy to install. Would have been easier had I been able to remove the air box. With the tools I had, I wasn't able toget to the screws beneath the box. Other than that, I was able to squeeze everything in. The change in power and throttle response is very noticeable, and the sound is great! I can't wait to finish it all off with my new exhaust!
