pursuit2550 Posted May 24, 2009 Report Share Posted May 24, 2009 I will hopefully have my PCM back from justin Monday or Tuesday. I am currentlly running the stock ACDelco iridiums. Should I run those or the NGK TR6. What should I gap them too. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted May 25, 2009 Report Share Posted May 25, 2009 You definitely need the NGK TR6, I believe the gap is .060, but I may be wrong........ Quote Link to comment Share on other sites More sharing options...
shakesvho Posted May 25, 2009 Report Share Posted May 25, 2009 NGK TR6 Spark Plugs #NGK-4177 Gap To .035 Quote Link to comment Share on other sites More sharing options...

T-Bag Posted May 25, 2009 Report Share Posted May 25, 2009 (edited) I just replaced mine with new OEM's. Runs awesome! Those are pre-gapped. AC 41-985. Good luck. Edited May 25, 2009 by Bad aSS Silvy (see edit history) Quote Link to comment Share on other sites More sharing options...
JennaBear Posted May 25, 2009 Report Share Posted May 25, 2009 .035 with that blower, and either the NGK 55s or TR6s. Quote Link to comment Share on other sites More sharing options...

5752 Posted May 31, 2009 Report Share Posted May 31, 2009 .035 with that blower, and either the NGK 55s or TR6s. I'm running a Procharger P1SC. What gap should I set with Champion RS14YC6 Copper Plus? Quote Link to comment Share on other sites More sharing options...
casper Posted June 17, 2009 Report Share Posted June 17, 2009 to b honest none go with the tr7 theyre ur best bet Quote Link to comment Share on other sites More sharing options...
kelleyperformance Posted June 17, 2009 Report Share Posted June 17, 2009 (edited) two heat ranges cooler is too much for a radix/procharger IMO. id stick with the TR6 @ .035 like everyone already said Edited June 17, 2009 by kelleyperformance (see edit history) Quote Link to comment Share on other sites More sharing options...
Krambo Posted June 17, 2009 Report Share Posted June 17, 2009 two heat ranges cooler is too much for a radix/procharger IMO. id stick with the TR6 @ .035 like everyone already said Agree. The Magnacharger is actually designed from the factory to run with the stock plugs. If you change pulley sizes or do additional mods over the stock Radix kit, the NGK TR-6's @ 0.35 is your best bet.

supenia4 Posted June 18, 2009 Report Share Posted June 18, 2009 I installed my radix112 in my 04 silverado with 26,000 miles on it and kept my stock plugs and the truck runs excellent! Quote Link to comment Share on other sites More sharing options...

shakesvho Posted June 29, 2009 Report Share Posted June 29, 2009 I was just ordering a set of tr6 and notice everyone goes by the part number now #4177(don't see tr6) and it looks to have a new type of tip "V", anyone try the new "Type" Quote Link to comment Share on other sites More sharing options...
Jaymz Posted June 29, 2009 Report Share Posted June 29, 2009 I Just bought new #4177, but it's not a "v" type. Never seen em I guess.. Quote Link to comment Share on other sites More sharing options...
