Installed (without engine covers):
Impressions prior to being tuned for the intake: AEM, hit the nail on the head with this design. Very OEM looking, clean and fine attention to detail. Also includes a filter minder, letting one know when it needs to be cleaned just like the factory does. The AEM is definitely throatier at throttle, but nothing really noticed SOTP.
Impressions after being tuned: The throttle was much snappier, and pushed through shifts more seamlessly. SOTP say that that there were gains, definitely not huge like a cam or a blower.
Final thought: Would definitely purchase this kit again.
