Looking to purchase some plugs for my Evo VIII. I want to go with stock replacement plugs.

So here's the confusion.. Apparently you're not supposed to gap these plugs..

The service manual says this:



and the NGK website says this:



Can I just buy those plugs and install or do I try and cutting down the gap because it's at .032 and the manual says max is .031 ??

Thanks

 

gap them at .24

 

I think you meant .024

Using the irridiums be sure to use feeler gauges to check the gap and not a gapper tool as this could damage the tip.

They say they are supposed to be pre gapped but I trust no one

 

I have minimal mod ( catback and drop-in filter) and mine are gapped .026 without any issues.
