    Default Iridium plugs

    Ordered some NGK iridiums. Question is do you guys check for gapping on these plugs, don't want to damage the center iridium piece.

    Yes. Better to check and adjust than trust that they were pre-gapped properly for your application.

    Absolutely check them, because they are more than likely NOT correct or even the same from plug to plug. Just a note when adjusting the gap on iridium plugs, there is a special tool to do so, don't use the old turn dial type adjuster or you will damage the electrode in the plug.

    You can use the turn dial type tool. There is a hole in the tool for bending the side electrode, you don't actually use the thickness measuring edge to open up the gap, you just use that edge to measure the gap.

    Good info using the center hole, thanks.

    To get back onto topic..

    I've just ordered two sets of these (both for me and a friend). Never messed with plugs before, what tools would you guys recommend to check the gapping and what tool to adjust it if needed. Preferably with an eBay or Amazon link.. that would help!

    Cheers!

    I bought a feeler gauge on eBay. Checked the gap and they all seem within spec.

    Exactly! The one and only time I used iridium plugs, the center electrodes were gone in 5,000 miles. I'm talking all six cylinders, on a vehicle with no known issues, check engine light off, no PD codes. Vehicle still ran, amazingly. So I'll not ever use them again. I'll just stick to platinum plugs. Never ever had a platinum plug lose the center electrodes.

    They were NGK's, btw.

    That's why I asked a mate of mine worked at an auto parts store and when they first came out he fitted them only to find the tips missing at the next service.
    Just curious to see if the issue has been fixed or not.
