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.

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. |

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.

Any time would be fine, really. They're cheap.
