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

10 minute job. Fit great. How well power improves? Who knows, it's a small investment.

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.

Don't know if these things do a whole lot but the part of the TB it smooths out sure looks like it needs this.

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

Very easy to install. It gets a little bit better mileage (like .5) but feels smoother in the throttle.

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.
