I must admit I installed this spacer at the same time as injector spacer and 18psi regulator spring as well as opening ports etc so can't measure performance of spacer alone but all up I'm very happy

As advertised, made in USA, build quality is awesome. Did notice quite a difference in acceleration, idle, and low end torque as advertised. The hardware as gaskets where also top notch quality. Great threading, chrome alloy finish, gaskets have metal plating in them like top brand fel-pro's. didn't need a fuel extension fittings being as how I already have a fuel pressure T fitting installed, without that you may need some, however the return line seemed long enough. Also you'll have to depressed the metal insert on your TV cable(if you don't have a electronic controlled tranny) and re-adjust your transmission cable length(700r4 you'll need to adjust it where it's slack but tight at closed throttle). I also have to loosen the back of my throttle bracket and put in nut as a spacer on the front mount bolt, along with with a longer bolt to accommodate the spacer. Be prepared to either space or angle your throttle cable bracket appropriately to prevent line crinks.

Not sure if I really gained anything from the install but it was cheap and went in easily. Had to order the fuel line extensions to work with it but it worked out in the end. Maybe the spacer and fuel line extensions could be offered in a package deal?

I wanted to try adding one of these to my truck, but didnt want to spend a lot on something that really didnt perform as advertised. This was easy to install, and came with all gaskets and hardware.

Throttle response feels a little better. Colder air going in. The spacer will condensate from the temp difference.

The quality of this product is good but...1. You do not get fuel line extensions with the kit so the steel braided fuel lines are pulled kind of tight. Not good considering the engine moves slightly and could cause a leak. On the box it says you could buy them separately... 🙄 REALLY?? These are not an option and the Spectra Performance kit although I don't like the spacer gives you the adapters.2. Since this spacer lifts the throttle body up one inch now the throttle cable and the TV cable going to the transmission are too short. I believe the cruise control cable might be adjustable but what's the point because the bracket is no longer correct.Anyway purchase at your own risk because modifications need to be made.

The one I received has some bad casting marks. Expected it to be somewhat smooth. Guess you get what you pay for.
