Jeff or anybody else,
what's the tap size that you used for the greddy egt probe? Thanks in advance.

Best regards,

don

Sorry, don't know. My engine rebuilder installed the probes when the engine was out of the car (easiest way to do the rear but expensive ). Doesn't the manual state the size?

1/8" NPT

Jeff,
I didn't buy it yet...I bought mine from fastboy who sold his vr4...and the egt started acting up and apexi does not want to warranty it. so I am buying a cheaper one.

Joe,
thanks so much buddy I think that's the same size as the apex'i egt so I can swap them

i didnt tap. I drilled two holes and welded them in.
