Uses the longer BPR5ES spark plug to better control correct combustion. The shorter stock plug (BPMR6A) is not available in a 5 heat range, which is perfect for this motor, so 5 heat range plug reduces plug foul, and increases plug longevity.

Please order a BPR5ES plug to use in this cylinder insert if swapping from the stock setup.
