Im goin to put a short ram intake on my car once the warranty is up and I was lookin at throttle body spacers to and I was wondering if they really do any good or if its just a bunch of bull.

well tb spacers help keep heat away from the tb and are supposed to keep the intake air a little cooler, but it really helps on boosted builds. i dnt believe it does that much for smaller N/A engines (like me whose gonna stay N/A thru college bc i like my 35 MPGs!)

it actually doesnt help anything at all and makes the rear head run hotter from partially blocking the coolant flow.
how is that for a good answer?

Really? How does it affect the coolant flow? No offense but that makes no sense to me.
03-07-2010
the coolant flows into the front head from the point where the thermostat housing is. it flows through the front head, through the LIM, and into the rear head. however, in the LIM there is a split in the flow and runs up through the throttle body and then back down to the rear head. if you block the flow to the throttle body, you block part of the flow to the rear head.
make sense?

WHICH...can cause heat spikes in the rear head/rear bank of pistons...that in turn = no bueno

Alright. I guess if thats the case Ill just do the intake. Thanks fellas.

It is funny that you guys mention the throttle body spacer causing the rear head to be hot. I just picked up an l67 for parts that was blown. It had the ZZP throttle body spacer on it. And what was wrong with the engine? The center piston on the rear of the block chipped/blew. Coincidence? IDK, but very interesting.

^^Probably NOT just a fluke.

Just a fluke. If anything the front pistons go first. Probably just the weak link.

hmmm
so, is the hole on the left hand side of this throttle body (next to the main passage, the hole you are talking about?

No the two holes in the s/c under the main bore.

03-17-2010
Oh well same thing. The hole you were looking at is the pcv inlet hole.
