Tapping for VPC temp probe

[MarkIII4Me]

Can I mount it in the throttle body? The manual states to install the probe in the intake manifold, but not after the cold start injector. I'm afraid the probe will get saturated where ever I install it in the manifold due to the position of the CSI.

The manual says that the probe can be installed in the throttle body, but preferably in the manifold. I just want to know what the logic behind this is. Maybe less chance of heat saturation?

Also, do I have to source a bung for the temp probe or can a tap directly into the tb for the size of the probe and screw it in? Again, I figure that there must be a reason for the bung Maybe to separate the probe from the temp of the surface it's mounted to? The manual does say to wrap the probe threads in teflon before installation. But that could just be to keep it air tight.

Thanks for any help

Where are you getting that It's supposed to be in the intake manifold? It's supposed to be in the I/C pipes before the TB according to the manual.. Only the MAP sensor should be connected to the manifold..

Also, you didn't get a 'bung' with your temp sensor? Mine had one, I tapped & silicone'd it into the I/C pipe before my TB.

Good luck man.

From the VPC manual:

Bought mine used from a member long ago. So non no bung

Can I still source the bung from any online vendors?


Good luck man

i used a bolt with the same thread.

I don't get it. Did you drill out the bolt and tap the center for the temp probe?

no. i went to the hardware store and found a bolt that the temp sensor screwed into properly. then i used that bolt as sort of a bung. i drilled a hole in my ic piping and just tacked it a bunch of times.. checked for leaks.. and it was good lol.

No kidding. I didn't know hardware stores carry bolts with NPT threads in the center. Any idea where I can source a bolt like that?

I used a brass 1/8NPT Hex plug for my bung. Just drill and tap the thing and it's good to go. Make sure you use a hex head bung as a square head will not work as well.
