LOSTAR Throttle Body Booster For 1985-1996 C4 Corvette LT1 and LT4 engines

It's not going to add any horsepower, and is almost certainly unnecessary to have, but it fits well and is solidly made.

Took a little while to figure out how it’s installed, but other than that it works great! I could notice a difference right off the bat when starting the car after installing it.

Nice part , fit well!

Good fit and relatively good finish. I had to de-burr the edges a bit with a half-round file. There was a bit of cast leftover that needed to be removed and rounded the edges a bit as well as they seemed a bit sharp. For the money I spent on it, not bad at al.Performance wise I don't expect much (Have not driven the car yet). Some testing has been done on these things and it seems they improve airflow 30-40 CFM. Does that translate into actual performance gains? Who knows.

Cheaper than the others and does the same job. Machining was ok, just needed a little file kiss. No big deal. I installed this along with a modified (removed the center section fins) air filter housing and can hear and feel a little differnce. For 20 bucks? Why not?

Installed don't know if it works or not can't notice any difference

Didn't notice any increase in performance ir fuel economy. Quality was fine, install wasn't too bad, but I would recommend a new set of gaskets for your throttle body, as you have to remove the top plate in order to install.

I already have one on my Vette!
