YHB Throttle Body Booster - Air Foil - Fit Chevy Corvette Camaro Firebird Impala Caprice tuned port TPI, LT1 and LT4

Install is a piece of cake, works as it should. Would recommend to other C4 owners.

This 85 C4 Corvette throttle body intake airflow splitter was easy to install. Improvement not noticed

It fit but it wasn’t a perfect streamlined transition into the throttle body. If you’re good with a dremel you can make it fit good thing is it’s larger than it should be so you can smooth it out to fit perfectly. You can always take material away. It’s tuff to add.

When I first got the Trans Am , it responded a little slow with the throttle . after install of this mod, it drives fabulous . responses quick and what you would expect from a performance vehicle .for 25 dollars, it should have been done from the factory. I think everybody should invest in this mod if they want to have a superior driving experience with a LT1 engine.

Product description photo titled "AFTER" shows the item installed, facing Backwards! But this is a crude copy or a Hypertech air foil. Who knows, maybe the manufacture used to cast them for Hypertech. Works the same. Has some rough areas but nothing to be concerned with. Fits in the throttle body as it should. Even when it is facing as it should. Back in the day, test with name brand air foils showed an increase of about 35cfm. No reason why this cheap copy should not do the same.

Used on a 95 Chevy Impala SS. Edges could use a lil polishing but overall quality product. I’m satisfied.

Heard it more than I felt it. Great for the money

I know I shouldn't expect too much from the part seeing how cheap it is but c'mon. Provided screw had no threads, so securing the part was not gonna happen. Not a big deal if I had some extra screws that would fit or even a hardware store near me. But I don't. Also edges are pretty rough. Ordered a replacement. Will update depending how much worse or better that is. Save yourself the headache and don't buy.
