Thread: Phenolic Throttle Body Spacer [*]

Thats what I did but it was a 65 shot.

I still have it too, its on my old engine just sitting there with the nitrous jet still screwed into it.

I still have a throttle body spacer, but its made of billet aluminum, and is more of an adapter plate to bolt my LS1 TB onto my GenV rather than a spacer to cool things off.

Header wrap...worst thing ever invented for headers, end thread. I would never put it on my car, or anyone else's, even if its only on the cross over and nothing else.

Heat shields...talk about as big of a gimmick as the next thing.

You dislike the Header wrap because of it causing headers to rust faster or what? Enlighten me Farns.

Header wrap does its job, but at a big price.

Wrapping stock manifolds, or after market headers holds in too much heat and causes them to split and crack almost every time. Ya, it keeps down under hood temps. But is it worth it to scrap a pair of headers from one of our cars? For what they cost....not worth it to me anyway.

If anything, have them coated, and call it a day.

Just my $0.02 on that.

Not a gimmick depending on their application. There's a reason all the stock parts have aluminum heat shields... To protect a lot of the nearby components from the cooking radiant heat of the exhaust. If they didn't do much it would be cheaper for the manufacturer to just delete them from the design.

Similar setups are used in jet engine housings to protect sensitive equipment from radiant heat and it works well. Standing near a jet engine, with a fairly thin square of aluminum hold it in front of your face and the heat is gone.

Aluminum reflects nearly all of the infrared energy that strikes it, so it offers plenty of protection from radiant heat. Though, it does nothing in the way of stopping convection.
