I see that our Beast takes Iridium or Platinum plugs. I have used NGK V-Power with good results, can I use the V-Power plug without any addverse effects? :thinkerg:
Part number 2315 for the 1 step colder and number 6510 for the two step colder. Just an FYINGK have both a 1 step and 2 step colder plugs option with the Iridium IX's. The LZTR6AIX-13 is the 1 step colder and the LZTR7AIX-13 is the 2 step colder. I believe that the plug gap should still be at .050 with both of these, but someone may know otherwise.
Rule of thumb is For every 100 hp over stock you should drop down 1 step colder.. FYI..when ever i boost a motor, i go 1 step colder. in most cases i have to tighten the gap also. you'd laugh but i run a .022 in my 4 banger @14psi.
truck does have dual plugs though so must not matter as much. but either way i would drop the heat range regardless.
These are what I'm running now. First plug change around 50K I used the stock double platinum plugs but they looked like crap after I just changed them to the v-powers last week. I have 73k miles now.Yes..... I ran the normal Copper plugs for quite a long time when I was NA. They don't make any colder heat ranges so they're not good for FI.
These ngk vpower copper plugs we are talking about will work for racing. I ran my new personal best last sunday and it was on these copper plugs. Like HB said he ran them in his N/A set up too and they worked great. They are stock heat range so they will work just the same for you.Dave, what's a good plug for a stock engine? I want to change before racing starts but not sure on a good plug?

2315's are one step colder. You shouldn't need those unless your running boost or nitrous, but I would stay with the iridiums. Great plugs!i currently have NGK LZTR6AIX-13 2315. been running them since 30k miles ago and now i am near 100k. its time to change out these plugs. what plugs should i get? my engine is stock N/A with bolt ons and minor cam. should i just get the vpower coper plugs that you guys are mentioning?
when i first got the plugs at 30k ago. i was planning on running boost. but changed my mind. i just might get the same plugs. thanks for the advice2315's are one step colder. You shouldn't need those unless your running boost or nitrous, but I would stay with the iridiums. Great plugs!
