Description

Factory spark plugs wear out and degrade combustion efficiency, robbing your Prowler 500 of power and throttle response. The Powermadd E3.39 restores optimal ignition timing with Diamond Fire electrode geometry, delivering quicker flame kernel development and more complete fuel burn in every combustion cycle. This translates to measurable gains in acceleration, fuel economy, and engine reliability under load.

Built for the demanding conditions of off-road riding, the E3.39 is engineered to maintain consistent performance across varying RPMs and fuel conditions. If you've noticed sluggish starts or reduced power during hard riding, a fresh set of these plugs will restore your engine to peak output.

  • Diamond Fire technology
  • Optimized electrode shape
  • Enhanced flame kernel
  • Faster combustion initiation
  • Improved heat transfer
  • Localized pressure front
  • Complete fuel oxidation
  • OEM fitment: 2017+ Arctic Cat Prowler 500
  • Bolt-on installation
  • MPN: E3.39
