HKS M-Series Super Fire Racing Plugs

Hks Spark Plugs. CERATO GT

Certainly make a difference up top. Few more mods and a tune should get the potential out of these upgraded plugs. Smoother idol on cold start.

Hks m series

Idols smoother but absolutely no performance gain at all with the MSD coils as well

Best upgrade

Currently using just a box tune on proceed, these plugs made a huge difference, every gear feels like it had a bit more power when I'm pushing it. Was definitely worth the upgrade

Shaun Boyce
An excellent mod!

Have installed these with the MSD ignition packs, and what a change! Feels smoother and much happier through the rev range!
