Review on Airaid PowerAid Throttle Body Spacer 400-590 by Brandon Reid

Revainrating 4 out of 5

In any case, the throttle response when idling from a standing start was noticeable.

Definitely better throttle response from idle to 3,000rpm. Not really worth $120, but with the intake system combo, K&N noticed a difference. Around $400 in upgrades might not be worth it for most consumers.

Pros
  • Installs in minutes with simple hand tools
Cons
  • Reliability
