The bung can be blanked with a bolt & teflon tape if you're after a somewhat reversible mod.
Yep. Whether or not I use that method will depend a lot on the construction of the sensors (will they stay together in that location).
Drilling a port in the manifold would probably be the best solution, but I don't want to drill holes in things if I don't have to.

This is the first time I've seen the term HSRK used. Looked it up and it appears to be a fast-responding probe and/or relocation.
I like the idea of a faster-responding sensor, but I'm still on the fence as far as relocation goes. Maybe I'm misunderstanding the purpose of AIT relocation, but it seems to me that it would make more sense to put the sensor the ECM uses in the manifold. But I guess it depends on what the ECM does with the data. If the ECM is already compensating for the additional heat gain of the ducts, then the manifold may not be the best place.


Thanks for all the input. Feel free to offer more tips and suggestions.


Somewhere down the line I would like to see how much the TB heaters affect air temp. But I'm getting ahead of myself.
