Heated TB is Only a problem when/ If it Heats the air going through it. Phenolic spacer will do Dick in Real life as the Intake manifold is directly heated from the Cyl head and incoming air charge is in the heat of the manifold Much longer than the TB. Your cooling (reducing it's temp a bit) the throttle body gives a fairly marginal heat reduction to the intake air.
I have a phenolic spacer for the manifold now, it may not have been clear but I was referring to getting a phenolic spacer for the manifold not the throttle body. I was just testing the difference the before adding the phenolic spacer on the manifold.
@@thecucaracha right on man I have to take my TB off my 92 to clean the IAC valve and I figured while I was at it I'd just do a coolant bypass I did it in my Trans am and it really lowered the throttle body temp I beleive the hose is like 5/16th but im not 100% sure cant find really any write ups online either
Yeah I haven’t seen much either. It makes a decent difference on the Miata. I’ve got a phenolic spacer to go between the intake manifold and the head to block heat transfer but haven’t got it on yet. I’m sure with that on and the bypass there will be a huge difference.

What size fitting did you use?
Honestly I don’t know. I just happened to have some spare fittings laying around and found one that fit.
