    One of the questions we quite frequently get asked are, What are manifold insulators? What do they do? How do they work?

    Here's a link that can provide a better understanding of real world benefits this modification can make on the dyno, down the strip and through day-to-day driving.

    And, NO! Our insulators and spacers are not made from timber lol

    The insulators do work, with a CAI the combination works better

    Is it a good idea to change the spark plugs while the top is off? I have a VZ and got the 12mm also should I put in new coils even if mine are fine?

    It would depend on how many kilometres your car has done to on the current set of plugs be honest. If they have travelled over 80% of their service life, then it would be a good idea to replace them. The fact that the insulators are reusable though, you're not obligated to having to do the plugs at the same time as you install the insulator.

    If you have any more questions please don't hesitate to ask.

    Kindest Regards,
    Steve
