Question for the tuners and possibly racers out there.

I have some old Plug Ring type cylinder head temp gauges That I'd like to fit, just so I can see what's going on for interest more than anything else.

As the plugs are inset a little the ring sensors won't fit unless I Dremel out a little space for the 'sticky out bit'.

I trust it's safe enough to do this, and I won't cause a crack stress riser as a result...

photo please

Ok so cylinder head and spark plug recess



Ring sensor



So I would need to relieve just a little section to allow for the 'sticky out bit', it won't bend sufficiently to clear.

You can trim the plastic to give clearance for the Spark Plug.
The plastic gives some strain-relief to the cable.
Make sure the hole fits the plug as a loose fit.

Mine got jammed on the threads of the plug and the cable got pulled out.
The plastic doesn't do much anyway, as the TC is "crimped in".


Got mine here, bit of a wait
