Krambo Posted October 13, 2011 Report Share Posted October 13, 2011 (edited) Some NGK (TR series) plug info for our trucks is listed below. Personally, I only use copper core plugs for boosted or deffinately for nitrous. Only use the "BR" (non projected) series for nitrous as well (I am not going to post the BR series here as it will just add confusion...besides, I know I posted the BR series info somewhere on this site in the past). Do not force gap Iridium / platinum plugs or risk damaging the tips: Heat Range 5 Plug Name - Stock Number - Factory Gap TR5 - 2238 *Copper Plug* (0.035") TR5IX - 7397 *Iridium Plug* TR55 - 3951 *Copper Plug* (0.055") TR55IX - 7164 *Iridium Plug* Heat Range 6 Plug Name - Stock Number - Factory Gap TR6 - 4177 *Copper Plug* (0.035") TR6IX - 3689 *Iridium Plug* Heat Range 7 Plug Name - Stock Number - Factory Gap TR7IX - 3690 *Iridium Plug* Heat Range 8 Plug Name - Stock Number - Factory Gap TR8IX - 3691 *Iridium Plug* Note TR* Plug Specs 14mm Thread .708" Reach 5/8" Hex Projected Tapered Style Edited October 13, 2011 by Krambo Spelling (see edit history) Quote Link to comment Share on other sites More sharing options...
