just a thought, if i take off an block the lines going to and from the throttle body,that come from the thermostat housing ,the hot water-coolant from the radiator wont go to the tb,thus making a cooler fuel discharge ,better milage,and a few hp in the process???? any thoughts or problems with this input??,thanks keith

I live in CA and did this mod to both of my F-body's and my Fiero. I don't live in a cold climate though, so I didn't care about deleting them. I personally didn't notice any Seat Of The Pants feeling from the mod on any of my cars! I drove my Fiero up to South Lake Tahoe one time, and came out from the hotel the next morning and had a little snow on it. But the car was fine, but that was my only experience with a cold climate on the car!
I notice on my Fiero though, that the upper plenum is MUCH easier to take off now!

that would make it easier, if i take them off @the tb,i was thinking take the off @the metal lines near the thermostat housing,it get cold here,in the late winter ,what problems will it cause when cold?

it was there to prevent icing in cold climates. removing it will make very little differrence in intake temp charge, it is a smoothe surface and the air is not in contact with it long enought to impart much heat from it. the intake is usually as hot as the motor anyway, and the air spends alot more time there,and it isn;t really smooth....
shouldn;t be a factor in your area, you don;t get that much freezing temps, but you can be the judge of that.

Took mine off and we get some snow and cold here in northern Va. and it still runs fine. And dont block them off, simply put a short hose from inlet to the outlet.

Agreed. The air isn't there long enough to matter. All you've done is remove the protection against TB freeze up.

It also prevents freeze up if you run your cruise control at the same speed for long durations of time in humid environments, even warm ones.

I've pulled them off all my Fieros (and it does get cold in Reno) and haven't noticed any difference. Makes for a cleaner look and it's easier to get to the distributor to service it. I would suspect that the crankcase vent that's just upstream of the throttle body would provide some heat--and when the car's running, the engine compartment is never a source of cool air.

How/What do I use to plug the areas that the tubes went into at the TB? Thanks!

You don't have to plug those areas at all if you don't want to. Won't hurt a thing.

On the T-stat houseing there are 2 hoses that go to the TB just pull off one end each and loop them. Nothing else needed.
