When I had the tranny temp gauge installed, I didnt notice where the probe was installed.
Its in the pan.
I want to remove it and put it in another location but was curious as to what size plug goes in there.
Thanks.

 

1/8 NPT is what mine took hope this helps.

 

Is your turbo whistle very noticeable with no silencer ring and the hole in the airbox?

 

No it is just right you can hear it but it is not annoying. And by removing the baffle in the TQ tube it also breaths better.
