HKS M45iL Spark Plugs

Shipped and delivered in a reasonable amount of time. Checked the gaps and they we're all good. Installed and everything worked as advertised!

The spark plugs arrived quickly and were properly pre-gapped for a quick install. My Stinger is running great!

Plugs work great. Car ran a 12.3 @ 114mph with lap3 tune, plugs, k&n intake, and muffler delete.
