Will 90-91 TB, and Plenum Work???
Hello, I was wondering if a 1990-91 Throttlebody, and Plenum off L-98, would work on my 88 L-98 coupe?
Thanks in advance, Tom
Thanks in advance, Tom

Whoops, I saw you just said plenum. I guess if you use the runners of your 88 the cold start should work...

I guess another question I would have is, what years did the cold air injectors come on? Thanks
