INSTALATION WAS DIFICULT FOR ME A 78 YR OLD ADDED MORE ACCELERATION.

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.
