NGK LTR7IX-11 $8.99 or Autolite XP5263 $5.99-$6.99 (also been seen to have a $2 mail in rebate). I've used both and like the Autolite better and their easy to find while being cheaper. Both gapped at .032 for FI sometimes a retune maybe needed. So check the gap on your current plugs and go with that if your car is running good now at that gap for your tune.

i'm hearing NGK LTR7IX-11 iridium is not good for FI...or maybe it was just for nitrous that it's not good for.

These are the recommendations I got from Jesse- approved by Arno for use with the IPF S/C kit:

Listed below are the 2 replacement plugs that are 1 heat range colder than stock:

Denso Iridium plug: 5340 = ITV22
14mm Thread Size,
25mm (.984") Reach,
5/8" (16mm) Hex Size,
.031" (0.8mm) Gap
Heat Range 22 (one step colder)

----------------------------------------------------------
NGK Spark Plugs #739-LTR7IX-11
Iridium IX Spark Plug
14mm Thread Size,
25mm (.984") Reach,
5/8" (16mm) Hex Size,
.044" Gap stock ā Need to Gap @ .031
Heat Range 7 (one step colder)

I've not had the opportunity to personally experience either yet...
so can't offer any other insight.

Dang that is a tight gap!

I've been running the NGK's first at 0.037 then everyone talked about how the gap should be around 0.032. I closed the gap to around 0.034-.035 and at seemed to stumble a little bit at idle I open it up to 0.036 and fixed it but I get a stumble every now and then. I actually just had a misfire on my number 6 cylinder two days ago. From all the messing around I've been doing with my tune I might have fouled up the plugs.

I just ordered new NGK's and will mess around with it this weekend.

I had discussed with Vince if I needed to change around the tune for a smaller gap and he told me to use whatever gap "works." So I'm not sure wtf I need to do, tbh. lol.

I think for the IPF guys it is pretty well understood that 0.032 is the standard.

What is the stock gapping and what kind of plugs are stock? I've not done anything to my spark plugs since I got the kit. I'm running all stock specs

Me too, Vader. I have a replacement set sitting on the table, but I just never get around to changing them out.

When is it recommended to change them with the supercharger. I have 35000 miles on my car

IPF is recommending the NGKs LTR7IX-11 , or Denso 5340 ITV22, both are 1 step cooler than stock and both need a 0.031 gap with their S/C kit. Factory setting .044
Ihad installed the NGK about 2 k ago and does make a difference in performance Great Plugs

on ANY spark plugs if you gap them smaller they will run colder and if they are gapped larger, they will run hotter at the risk of a "spark blow out" <-google , which is basically a spark plug induced misfire

i would recommend running the largest spark plug gap you can without misfiring of any kind, and no larger of a gap than stock

while checking the spark plug gaps and then regapping for uniformity is a good idea (new spark plugs as they come in the box may have varying spark plug gaps), the spark gap should also be adjusted based on the power output of the motor, with induced misfire as the determining factor, and only as the need arises, go to either a smaller spark plug gap or a colder range plug; both of which if taken too far will also cause spark plug fouling

the OEM acdelco spark plugs are rated for 100k+ miles, of all of the plugs listed in this thread, and especially regapped, you're looking at a third or half at best of that lifespan


i would recommend for the LFX motors:

for anything under 300whp, the OEM acdelco plugs with the stock spark plug gap, with replacement at 50k miles or less

for anything between 300-350whp, the OEM acdelco plugs with a 0.040 gap, with replacement at 30k miles or less

for anything between 350-400whp, the OEM acdelco plugs with a 0.037 gap, with replacement at 20k miles or less

for anything between 400-450whp, the OEM acdelco plugs with a 0.033 gap, with replacement at 10k miles or less

and for anything above 500whp, a denso ITV22, at 0.030-0.032 gap, with replacement at 10k miles or less


if you gap your spark plugs too small or use too cold of a heat range on your spark plugs, you WILL lose power at part throttle and in extreme cases, cause idling problems such as stumbling or poor idle quality

smaller spark plug gaps for the sake of smaller spark plug gaps will not improve performance, and will negatively affect combustion efficiency, which you want as efficient as possible, for better power output, less misfiring, better fuel efficiency, and less carbon buildup in places you don't want carbon buildup

Interesting. Admittedly my knowledge on the spark plug and different gaps is minimal. I am currently at a 0.035 gap and my idle seems like it wants to stumble & has poor quality like you have suggested. I also had a random misfire on cylinder #6 the other day when I was leaving idle and had part throttle. What is more interesting is I just spoke with Vince and his suggestion (like IPF) is to gap down to 0.032. I suppose I can test our a larger gap and see if I have spark blow out or not.

Denso recommends a 30K mile replacement on the 5340-ITV22, but mine did require a re-gap down to 0.031 (0.8mm).

As an update, before I got rid of my V6 I opened up my gap to about .038 and my idle got significantly better and I still didn't have spark blowout. So my point is what works for one tune or car may not for another..
