Review on πŸ”§ Improved Smooth-Bore Throttle Body Spacer by Trans-Dapt - 2734 with Advanced Optimization by Smiley Edwards

Revainrating 5 out of 5

Easy Cheap Throttle Injection Mod

Easy Install, fits my 90 Brougham 5.7 TBI perfectly. It's hard to tell what the difference is because I've been making multiple mods at the same time. This spacer plus injector spacers with a heavy duty filter and modified air intake and intake air sensor relocation rated for 15-30hp torque. and more. The powerband also seems to improve at idle.

Pros
  • Easy Install
Cons
  • Long Lead Time
