Worked great and easy to install.

9 I bought this on a recommendation from a dealership service department. My hope was to eliminate throttle lag, give it a little more oomph on the go, and make it growl without being obnoxious. It gives me all of that. I didn't dyno before, and probably won't now. My butt-dyno tells me all I need to know. I got more than what I paid for. Great product!

The HPS post-MAF air intake tubes gave the engine a bit deeper of a growl at wide-open throttle and when combined with aFe or K&N drop-in filters, there was a noticeable improvement in acceleration. I did have to trim about an inch off each breather hose, but YMMV. Would definitely purchase again.
