Decent item at a decent price
Install was smooth, product seemed to help with throttle response but it may just be in my head. Already had a cold air intake so I figured this part will only help with better air flow.

This is great for the mighty L98 engine.
Install is a piece of cake, works as it should. Would recommend to other C4 owners.

Fitment is a little sloppy
It fit but it wasnโt a perfect streamlined transition into the throttle body. If youโre good with a dremel you can make it fit good thing is itโs larger than it should be so you can smooth it out to fit perfectly. You can always take material away. Itโs tuff to add.

Did anyone notice the picture where its installed backwards?
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.

Best mod for Lt1 engine
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.
