Stratified Notes

Fresh spark plugs gapped to the correct spec will prevent misfires and loss of power under high boost and load conditions. Usually, misfires under wide open throttle are often related to spark plug gap and worn plugs.

We recommend this one-step colder plug for highly modified engine to reduce the chance of pre-ignition in direct injected tuned cars. More Here.
