Review on Enhance Ford Performance with aFe Power Silver Bullet Throttle Body Spacer - 46-33017 by Knate Scarpelli

Revainrating 4 out of 5

Eco animal power! for fuel system

Bought for my 14 F150 Ecoboost. Noticed lower performance. Also increased gas mileage by almost 1 mpg. Instructions were easy to read, fairly easy installation, maybe 20 minutes. I only gave four stars because it's a bit pricey for what it is and there was no sticker on it. I also have a secure Stage 2 intake and a secure 4" tuned exhaust. They were done about 10,000 miles before I put the spacer in.

Pros
  • Internal bench tests showed the maximum increase to +16 hp. and +17 pounds. x ft of torque
Cons
  • Requires bushing
