Review on πŸš€ Airaid PowerAid Throttle Body Spacer 400-531 for Improved Engine Performance and Efficiency by Darius Carraway

Revainrating 1 out of 5

Just installed. on the fuel system

just fitted 27.08.2016. What I noticed from behind is a whistle, which doesn't bother me at all. I like the elegant look. I installed it on my 5.4L F-150 Harley-Davidson engine with Roush CAI and will provide an update report in a few months.

Pros
  • delivery was very quick
Cons
  • boring packaging
