Gapping Denso iridiums

About to put a set of Denso iridiums into my Renntech E60RS, has a 119 32V motor, using 11:1 compression. IQ 20 plugs. Any reccomendation on gap? Stock is .032" the plugs come as .04".

Any thoughts?

Thumbs up Go with the Manufacturer spec...

Generally speaking there is no reason to deviate from the MBZ spec no matter which brand or style of plug you're installing. I'm just about to change mine to the iridiums and will follow the spec. It's based on the engine design and specs, not the plug design.

Let us know how you like them and as always, enjoy the ride,
Greg

Be careful if you try - Denso says that there is a good chance the plug can break due to the gapping. That would be a BAD thing!
