Let me start with, I've never used Airhog, with that said I will say once I find something I like I stick with it. When ever I get a new vehicle first two things, last time on the way home from the dealer, I get a K&N filter,(if I don't have the $ for a K&N cold air intake), and a cat back flowmaster 40 series delta flow. I've never been impressed with the optima batteries, I buy generic but air filters, K&N is tried and proven for me. Flowmaster out the back:shades: That's my two cents . . .keep the change.
