    Excellent info, though it would piss me off to change my plugs out every 30k, cuz that's once a year for me. So I put the denso iridium long life plugs in at 30k. Like ya said, no increase in performance, just a decrease in the intervals, kinda like using a synthetic oil over a conventional. So these plugs I plan on swapping them out at 100k unless I notice any probs, then every 60-70k after that. Thanks again for the expiramenting you have done.

    Stupid questuon: since there is a given range, .039-.043, do you get better performance from your spark plug gap being on a specific side of the gap range?

    They give that range cuz ya can't always get it perfect. I would say get it in the middle of the range, that way over time whether the gap closes or opens you got play.

    This ^^^^


    However, When tuning a race vehicle, I would increase the gap to get a larger spark. This is generally not done on a DD, as too large of a spark gap compromises ignition reliablility.

    Well I checked the gap on the platinum plugs...everything was correct. I bought a set of NGK's and put them in and BAM! Instantly runs perfect with no skipping. It got really bad before I changed the plugs out. The platinum were only in there two weeks. This 4 banger doesn't like high dollar plugs.

    Quick question, the plugs for the 1GR-fe are single lead right? not dual?

    When you driving like old man, using premium gas and do your oil changes on time, spark plugs on 2gen after 37 K are at half life :D
