    They looked fine, but they were misfiring. OEM set were 100% cool.

    Fwiw if these are the same plugs that I was reading about from the n14 (mini cooper) they were really hard to get a good gap on without damaging the electrode, which was very thin and soft

    Edit: if you are interested in trying something different that comes in a colder heat range, a lot of the mini guys liked these:

    They are silver electrode which is pretty much the most efficient conductor that exists

    Hks will fit but the space around the plug won't allow for a socket of any wall thickness to be put on it to tighten it. Cyl head needs to be machined in that area to get this plug to be useable. Anyone doing a cyl head should ask the shop ro open it up a bi there so you can try the hks and other plugs out there.

    I think someone got the hks xl plug to fit by modifying a 5/8 socket I just can't find the thread right now

    Gapping these sux so much.

    But what are you currently gapping them at? I'd imagine fairly tight for what you run.

    Started at .022
    Then I went to .021

    Then I went high boost and tried .016 that is when that happened.

    Now am.at .019

    Gap on these is extremely critical. Get it right and they will give you very long service life at very high WHP levels. Stage 3 test car still has the same set we put in when we started tested. Car has close to 10K miles on it now, 5K of these were at varying power from 600-725WHP, hundreds and hundreds of pulls, literally one day we did like 150 dyno pulls in 8 hours. Car has never had a plug issue, still purring like a kitten with those same 5592's. Its also always possible to get a bad plug, running too rich foul a plug etc. But from my experience these plugs are pretty bullet proof when gapped right. Also AK you do not need to close the gap to run high boost we were running 30+ psi for a LONG time at .022 without a single issue I even ran as high as 40 psi on a few test runs, no need to tighten them down at all, .022 will serve you well.

    I agree 99% with all that. I just change them often bcuz it's so quick and I like to check em out

    I usually do them at 5k intervals. Or every other oil change. Since I only rape the car lol.

    I have found that at around 5-6k the gap increased from .022 to around .024

    So I'll leave this set as long as they do well and next set probably go back to .020 or .o21

    Actually these are really not hard to gap at all, but gap is critical. Bottom line if you are going bigger turbos, high boost, get rid of the stock plugs, if you are on stock turbos etc. The stock plugs are fine.

    took me three tries to gap these to perfection without misfires. On the second try just one plug a little off gave me a loppy idle. Even when off they never misfired under power. Once I got it right I have had no issues with them.

    Trick to gapping sensitive plugs is to not slide the cheapo coin tools and be forced to wiggle them out when they get stuck, gotta slide them in carefully without rotating and put the plug in a vice to tap the gap to perfección. Or use a superior measuring tool than el cheapo gap coin.
