Put this on my F150 Ecoboost. Kind of difficult to put on without disconnecting the hose going into the throttle body because it blocks the nuts. Aside from that a pretty simple upgrade especially if you combine it with the AFE intake. I'm loving the combo of this and the Magnum Force intake. Noticeable power increase and fuel economy is better. Seems a little overpriced for no more than it truly does but compared to a lot of performance upgrades, not too bad.

I have had these before on V8 engines and did not notice much improvement. However on my V6 Tacoma the low end torque is much better and throttle response seems more crisp. It does seem like MPG is a little better as well.

I did research before purchasing this product. Some people said throttle body spacers give off a slight whistle at times, but I was not expecting this. It's loud and high pitched. I will end up taking it off and trying to sell it. Sorry, I really wanted it to work out.
