Be careful. When I fitted the similar AEM short ram, I lost 9 HP in the mid range for a 2HP gain. Felt more powerful and there was more of a hit at the top end buit the dyno showed it was killing my mid range
Massive airflow can seriously hurt you mixture at wide open throttle
Fortunately I have a Unichip so I could change the maps to no loss at mid range and a 7HP gain at 6000.
Watch out for small children on the sidewalk if you fit one
They tend to get stuck in the filter
