Thread: spark plugs

  1. #1

    Default spark plugs

    hey guys just wondering if anyone knows what oem sparkplugs are in the 3 mps. i am thinking of getting some denso plugs and just want to know if it is worthwhile or are the oem plugs of a similar quality?

    i think stock plugs are fine, but if youve got a few mods its nice to drop down 1 step colder.
    im still running stock plugs and ive got a few mods, have colder plugs - just need to get around to installing

    MPSgarage supply them for a very good price.

    $25 last time I checked, Genuine were $32+


    Nowhere else supplies colder plugs either.

    Honestly mate unless you are running an advanced ignition timing and new ecu there is no advantage. Just get yourself some NGK plugs about the best plugs you can get to replace stock and still inexpensive.

    I got the standard ones sold by MPSG but have yet to fit them. I don't know if they are hotter or colder than standard fitment. Anyone got a torque setting for these BTW?

    I didn't notice any difference, I even went 2 steps colder.

    I only changed to colder plugs for the known benefits/safety issues that colder plugs allow. (As stated in the post above)

    I bought some NGKs Iridium plugs from Edge
    I installed them without any problem, but was experiencing some hesitation or stutter on WOT on stage 2
    I reloaded Stage 1, but this did not resolve the problem

    I eventually realised that the NGKs required gapping
    Stock MPS plugs are gapped at 0.028" or 0.71mm
    NGK Iridium plugs I measured at 0.038" or 0.96mm. Although their website states that they are pre-gapped to 0.043" or 1.1mm

    I re-gapped my plugs to 0.27" or 0.68mm as advised from Cobb for Stage 2 and I happy to announce there is no longer any hesitation or stuttering on WOT

    This ^
    There is certain special circumstances where you might need to gap them less, but that's when you get into higher power levels

    From stock, to GT3071, to substantially less modded, many lessons learned!
