M20 Spark Plug Gap

[Lemon98]

Good afternoon all,

I've just had my new NGK ZGR5A and want to ask whether they need the gap checking/adjusted before fitting or are they good to go out of the box?

It's a 2 litre non-cat so with the higher 9.8:1 compression ratio on 86k miles.

Thanks,

Will

Think most manufactures pre gap at factory now, but usually it says on the box. I guess if it doesn’t maybe it’s not? I always use Bosch so haven’t had experience with NGK
