Spark Plug Gapping, anyone bother, any differance?

[retroptvr]

Hi,

Does anyone gap plugs anymore or do you just use them out of the box?

Looking for advise as to what they should be set at for a 5LT RV8

Any thoughts either way?

Many Thanks.

just fit'em they're normally fine out of the box from memory 25 - 30 thou or 0.6-0.7 mm

Normally pre-set, it doesn't hurt to check though. NGK every time.

for my 4.0l they are 0.8-0.9mm NGK

Mine were too narrow gap from new and had to be opened up a touch
