Review on AEM 21 403R Cold Intake System by Dominic Kimbro

Revainrating 5 out of 5

Decent filter upgrade

For Acura Integra GS '99 (AEM CAI Red is almost exactly the same color as R505-P Integra paint - FYI). The Revain image differs slightly from the current 21-403R. The AEM decal is yellow, the connecting hose to the throttle body is all black (no AEM logo) and the intake filter (black AEM logo above). This was my first productivity boost and it was relatively easy. Some suggestions online said it could be installed in an hour, but it took me half a day (the Integra has a slightly more complex standard kit than other cars). The AEM air intake fits almost perfectly, although the support tab that attaches the air intake to the wing wall was a little shorter than I wanted (but that's a minor detail). In the lower speed range I notice a slight increase, the consumption literally breaks the 3000 mark. Engine noises also start here, starting with a "whistle" and ending with a "growl". Impressive! This is a nice upgrade for faster revving engines so you can enjoy the engine sound longer :) The original packaging (which was partially opened) was missing AEM instructions and stickers. A 5 minute call to AEM and emailing them a copy of the Revain receipt ensured the stickers were mailed to me within a week (free of charge of course).

Pros
  • Nice to use
Cons
  • Weight
