Spacer?

thread length/reach is all that matters. That should be consistent brand to brand. Any overall length diff should be in the body/insulator.

i did some searching and found the ngk cut back plugs. summit has them , would require a .040 spacer , decent price but......none of them are R plugs.  my wires are R but based on what i read on ngk's site, R plugs are to combat emi vs R wires are for rfi. for some reason i cannot look that plug up on ngk so i will have to call and ask if the make a cut back R plug.
NGK plugs with an R in the number are not resistor plugs.R stands for racing in NGK lingo. I was fooled by that for some time. I haven't seen any EFI issues with using helically wound suppressor wires and non resistor plugs with EMI/RFI interference -in my application.

the summit ad said non resistor plug. some plugs an R does mean race and some it means resistor, brand to brand thing. i meant meant resistor as in i need a resistor plug.  no response from ngk yet.

so come to find out in ngk's case, red pn# on the plug means non resistor plug. also i sent a pic of the cut back plug to the ngk rep last night to see what he can come up with. based on the specs of my engines his program says i should be running heat range 7 vs the 5's i am currently. 5 is hotter than 7 in ngk's heat range.

Here is a link to "all" the NGK numbering systems. I say all because the plug I was using is a R5671A-8  or 4554. It doesn't correspond to anything but the heat range at the end. This is where I got confused since NGK told me the R didn't stand for resistor and it doesn't for this plug.Apparently an R at the beginning stands for racing but if elsewhere in the number it is for resistor.

there a hard company to read lol  i really like the idea of the cut back plug style but they don't offer it in a resistor plug i guess. he only said they don't offer a cut back for my application. didn't elaborate on that but he did ask for specific info on how my engine was built. he specifically asked what my cold crank comp was as well as a few other specs. i was surprised that there data says i should be running a #7 heat range which is 2 heat ranges colder than my current plug which is a 5. i will give that a try and see what changes it makes but what i can say for sure is that at .024 gap on tr5 plugs vs the autolite copper ( stock) i did notice a better throttle response. i am now gapped .020 and do not want to go smaller which is why i am going with the ign ia coils.  honestly i  should be able to keep them gapped .024 and be fine but if need be i can always limit boost to 25 or 27 psi rather than 30.
