Don't we always use head washers to adjust the compression anyway? The main reason why standard plugs rob performance in these wee beasties is because the volume in the threads alters the compression.

I didn't see any head washers in Norvels - just copper washers under the glow plugs.

A turbo plug has a tapered base which seals into the head, which removes the need for the copper washers. But those washers are important to adjust compression


There is a much better way of adjusting compression than using conventional plug copper washers.

Use head shims!

I agree a turbo head button is far superior to a standard plug in a small capacity motor.
