Cross Ngk Plug Reference Spark

.
none of the manufacturers are consistent with heat ranges and it is difficult to make a chart to reference the plugs.

I thought Autolite 104s were 1 step colder and 103s were 2 steps? Brian, this is where the difficulty lies. AC Autolite Bosch Champion Motorcraft NGK Automotive Components (Original Equipment) Aftermarket Automotive Components Aftermarket Industrial Products. What about autolite 104's? I heard they were good.

Both Denso and NGK cross reference the 103 to the IT-20 and TR6. .

I started messing with my Larger Shot Nitrous Tune and had only begun setting it up, accidently loaded this instead of the finished product. Rather than throw that in the 1 whole step colder range, I put the 103's which are almost 1. On small shots the 104's would suffice, but I personally would elect to install a set of 103's. 35 is that right? how do i know if i should go colder? what kind of spark plug should i go with for my big block with a 200 shot, that doesnt get hit much? This was done on this Custom Dry Setup: With a slight mix of 103 and pump 92, 22* timing and AFR about 12. Hope that clears things up a little. 0 Mustang Cobra 93-95 w/ GT-40 Heads Plug: NGK TR55 (stock number 3951); NGK TR55IX (stock number 7164); Autolite 764 or 104; Denso IT-16 (stock number 5325) Plug: NGK TR6 (stock number 4177); NGK TR6IX (stock number 3689); Motorcraft AWSF-22C presidential fact and trivia (copper); Autolite 103; Denso IT-20 (stock number 5326) Plug: NGK BR7EF (stock number 3346); NGK TR7IX (stock number 3690); Motorcraft AWSFA-12C (copper); Autolite AR94; Denso IT-22 (stock number 5327) Plug: NGK R5724-8 (stock number 7317); NGK TR8IX (stock number 3691); Denso IT-24 (stock number 5328) Plug: NGK TR6 (stock number 4177); NGK TR6IX (stock number 3689); Motorcraft AWSF-22C (copper); Autolite 103; Denso IT-20 (stock number 5326) Plug: NGK BR7EF (stock number 3346); NGK TR7IX (stock number 3690); Motorcraft AWSFA-12C (copper); Autolite AR94; Denso IT-22 (stock number 5327) Plug: NGK R5724-8 (stock number 7317); NGK TR8IX (stock number 3691); Denso IT-24 (stock number 5328) Plug: NGK R5724-9 (stock number 7891); Autolite AR93; Denso IT-27 (stock number 5329) good info.

Maybe someone can sticky it to the top so that people can easily reference it? It's fairly hard to compare each manufacturers heat range since there are so many factors involved but this is, in my opinion, the closest match for NGK's heat range system, which was used in the chart. great post I was just trying too find all this out thanx alot for saving me time and a guessing game. ***Note: List is intended for reference only.
