The holes on the bottom of the throttle body where the coolant plate attaches were stripped. The screws would not thread into the body. Looks pretty but poor quality control. Sent back to Amazon.

I dont have anything to compare with so I assume that they do the job and are adjustable..

Excellent fit and I noticed an increase in performance works great. It took a little work to get the air duct on after the in installation the butterflies opening is a little larger so I stretch the plastic opening well worth the effort. I would buy this product again if needed.

I just installed this TB on my 1985 C4 and I finely got this car to idle wright. My original TB failed a smoke test bad around the shaft seals so I took a chance on this one so far so good. My C4 would never idle steady but this took care of it. For those of you who said your original coupler wont fit your wright I purchased the Eckler's Premier Quality Products 25107026 Corvette Induction Power Coupler and it was even tight but after a little time in the sun I got it on, it looks better anyway. Will repost if anything goes wrong but I think it was a good investment, I got real lucky and caught it on sale for 175.00 but I see it back up over 300 again Hope this helped

Beware, your stock intake duct will not fit! I am waiting for a response if I get one.
