Anyone have any experience with these guys?

Im closing in on 40K on my 13' (eeek i know:uh oh and was going to do a full tune up.

I purchased the silver cores from MMR so ill be doing a little feedback once i get them put in. i heard pretty good things about them from the FI crowd but i stayed in the stock heat range

Was it an issue (it happened) or a precaution?

just buy a set of FRPP cold range plugs. Nothing beats ford racing's reliability. Using them with my TVS setup gapped to 0.0035.

Brisk is a great plug we have been using them for years.

for a stock engine i would use the RR14

No it happened to me. I gapped them to .032 and they would misfire at around 6500 in 5th gear. Gaped them to .028 now.

i thought they came pre gapped

Gotcha! Blowing out the spark. Sorry, thinking back to my Lightnings and the issues they had with the older heads "shooting" the park plugs out due to the minimal number of threads.
