    What's wrong with the standard ones if they have lasted 80,000km?

    Thumbs up Re: best spark plugs and leads

    Leads are leads but many workshops will recommend using the OEM leads supplied by Holden. Good enough for turbo/blown cars etc.

    Plugs are dependent on what's done to your car. 2 types that are frequently recommended are:

    NGK TR6 (slightly colder plug)
    NGK BPR6EF

    Both of these willl be more than adequate for the job.

    If you're going to change them anyway, it never hurts to see if there's something better

    A search of the forums will reveal a few discussions on it already though

    Research BRISK LGS if you want to try something different. GOR-15LGS


    MSD leads are supposed to be the best in the market.

    BPR6EF-15's are cheap and effective but require regular replacement(15,000Km's)

    Hey mate how do you find the Brisks?

    I've run them in a few cars, including some supercharged 6's that are known to break down spark and they run fantastic, even though they have a 3.0mm gap.

    We also tried some Brisk GR17YPY in a VZ Senator and found 7.9kw.

    Cheers,
    Adam

    I like the oem Iridium plugs albeit a little xp over the Bosch bpr's, With leads oem are great. But with my LS3 have just changed them to the thicker MSD ones.

    Thanks, I had a previous mechanic swear by iridium plugs and some on forums suggested this was the go. So I need these and just change them more frequently:

    You can get the TR6IX Iridium version, I just don't like the idea of throwing them in for that long and not checking on them.
    Just be careful if you're gapping them as you can damage them very easily.

    As you say, if you keep Iridiums, pull them out clean & re gap as they last longer than the cheaper Bosch replacements.
