Enhance Performance with Airaid 200-540 PowerAid Throttle Body Spacer Review

I've definitely noticed an increase in performance. As for mileage, I'm not sure as I've had other issues that I'm working on.

Loved it, it did what it said it was designed to increase PERFORMANCE! And the only thing I can say is that it needs improvement. MORE STICKERS!

Part worked properly! And it was possible to install in about 30-45 minutes. The guy was very excited when he first saw the red part when he ripped open his HBD gift and again saw his gas mileage increase almost immediately after plugging it in!

Installed on a '95 Vandura 3500 (aka G3500). SBC 350 5.7L throttle injection fuel. It whistles the most at about half throttle. I went from an average of 9.5mpg to 12.9mpg! I think I'll see more when I take my winter tires off, but so far it's paying off pretty quickly!

This gasket worked great, I have a 350 V8 GMC engine with throttle body injection and it has really improved throttle response. He accelerates faster. Unfortunately I could not get any dynamo numbers. But I noticed a reduction in fuel consumption and also a slight improvement in fuel economy. Overall good product.

This throttle body gasket was originally supplied without paper gaskets (shown in gray in the picture). I emailed the supplier and they shipped the pads straight away with no extra charge. The spacer fits very well and all hardware is included. Thanks to this gasket and the new air intake, I got 4 mpg more out of my 1992 Chevy K1500.

Installed on a 95 Silverado Z71 350 TBI pickup. My truck has standard semi-aggressive tread tires, works really well and I've gone from 14mpg to 15.2-15.8 depending on what I'm doing. a day because I drive a lot and I got a solid 1-2 mpg. The truck has better throttle response, it idles a little harder but not bad at all, well worth the money spent on it if you have a tbi car get this item!
