Hi all,

I was given a set of Bosch Super 4 spark plugs today, that allegedly fit my Mk1 Octavia VRS.

What is the verdict on these plugs?

I just recently re-gapped my OEM plugs to 0.7mm (as a result of my remap), and was thinking about putting the Super 4 plugs in, but I was concerned because the gap cannot be adjusted on them.

Any views on these?

I tend to go for a slighly cooler running plug when increasing the power, not much experiance of the super 4's tbh. You could always try them and if not firing correctly as you have the working ones to fall back on.

Most NGK irridiums etc are 0.7mm std iirc
