Useful GEN V spark plug Info

**Jack B** · 11-19-2016

I don't know why they make it so hard to find some simple info:

Engine Spark Plug

Gen 5 -8.4L
Part # RE10PMC5 (Champion 3032)
Gap: 1.27 mm (0.050 in.)
Size: M14 X 1.25
.
It looks like the Champions come out of the box gaped at .045". This is not an easy plug to find, however, Advance Auto does stock them locally or at the distribution hub, which gets them in one day.

Great info Jack. Thanks.

I made a Gen 3/4 torque specification and maintenance tracker spreadsheet a while back, and one of the tabs includes the spark plug info for future reference:

If they'd allow forum users to attach Excel files, I'd attach it to this post for everyone to download. In the meantime, I've just been sending it to people's email addresses that ask for it...if anyone wants a copy, I'll send it your way.

That is a pretty nice set of tables. As a side note, I checked three boxes of plugs for the "as manufactured" gap setting, they all (some exceptions) fell between .045 and .050. However, two plugs (from different boxes) had the electrodes bent so that there was no gap. The take-away is, if they haven't been mishandled there is little or no setting required.

You may want to make a note, the G5 recommends a torque of 13 ft lbs. Another concern is that no lubricant should be applied, that would reduce the torque by at least 25%.
