this is troutchaser from northern Calif. I think my 07 hhr is a great ride ,if I had it went I was a teenager my mom and dad would has kill .but they love me any way . I am 69 years old now . I can put a bike inside or on top on the rack .it is great . It corner like race car and has all the power I need . Does a cold air filter help a lot ? Or not .should I put one on or not ?any help would be nice . God bless

 

I don't think it will boost the hp. I have a K&N set up on my panel, with a trifecta tune, it helped the power a little bit, but sounds better.

 

I love mine

 

Well "Hi" right back at ya!

Love mine, wouldn't part with them, they can be quirky sometimes....but that just makes 'em more fun!
