Hi guys,

Just bought an uprated up-pipe for my classic RA.

Questiom; what is the threaded boss for? If it needs a blank, where can I get one from?? What size thread is it anyway??

thanks in advance

 

Threaded boss is for EGT probe.

You can fit an aftermarket EGT in here if you want a gauge, but recommended not to fit the original (I think only newage wrx has up-pipe EGT anyway).

I think this may give the EGT sensor size.. but double check

Cheers matey!

So is i 1/8 NPT or M10x1.25 ??
