    Copper is the best conductor. So going to any other metal has zero to do with performance gains, just an attempt at lower maintenance costs.

    If your ski is stock, stick with stock plugs. If you are looking to do high boost, get the NGK LFR7AIX plugs which is one step colder.

    Got a 2015 FX SHO with the 1.8, what size spark plug socket do I need to buy? I only have 12 or so hours on it but I want to inspect the plugs and put some anti- seize on them.
