Review on Enhance Engine Performance with the JET 62174 Powr-Flo Throttle Body Spacer: A Comprehensive Review by Jay Williams

Revainrating 1 out of 5

No performance change

It matched my 2016 3.5L Ecoboost but did nothing at best. I didn't notice any change in performance. Unofficial mileage test (not a 100% course/speed match) while towing 5000 lbs. I've noticed a 20% reduction in mileage when using this (10.5 to 8.5mpg). With no trailer at the agreed distance/speed/temperature I have seen a 1% reduction in mileage (noise). No free lunch, if all you had to do was add strudel to the intake, Ford would do it. Returned.

Pros
  • Great product
Cons
  • I won't say anything
