Hello friends,
I have always wanted to know, is the heat riser really necessary on these TBI motors? For example, you see lots of folks flip the lids on their air cleaner housings, which would completely negate the heat riser. I even drove my '95 TBI 305 GMC for a year with the lid flipped and it ran fine year round, which tells me the heat riser is perhaps nice...it helps a little on cold starts...but that's it?
Do folks ever delete them just to clean up the engine bay?
I'm getting ready to do some tune-up and clean up on my 1994 Z71 and I'd love to know prior to getting my hands dirty.
Thanks.
