Engine-ready ignition for NGK 3365 and STIHL tools

Meet the Hipa CMR6HCU spark plug, crafted for a broad lineup of gas-powered garden tools. Its copper core, ceramic insulator, and robust seals come together to support reliable starts and steady heat management across demanding trimming, blowing, and cutting tasks. The result is a practical, real-world solution that practitioners can consider as part of a routine maintenance plan.

Key benefits at a glance

  • Copper core aids heat removal for smoother starts and steadier operation in mixed-fuel environments.
  • Trivalent metal plating provides strong anti-corrosion and anti-seize properties for longer life in challenging conditions.
  • Pure alumina silicate ceramic insulator offers high strength and efficient heat transfer, helping resist fouling.
  • Triple seals help prevent leakage, supporting cleaner internal components during use.
  • Designed to fit a wide range of NGK CMR6H 3365 and STIHL models, simplifying model checks and replacements.

How it fits your toolkit

Standards with a 10mm thread diameter, flat gasket seat, 12.7mm reach, 16mm hex, solid terminal, and a 0.7mm gap. These specs help ensure proper seating and consistent spark delivery in compatible machines.

  • Maintenance-friendly by design: consider a routine around 25 hours of use for cleaning and inspection.
  • Maintenance reminders and clear specifications reduce guesswork and downtime between yard tasks.

Real-life scenarios

From revitalizing a BR600 blower to keeping FS series trimmers ready, this plug offers dependable ignition that supports quick starts on cool mornings, confident throttle response, and steady performance through thick grass or hedge work.

This 4-pack is designed for ongoing use across compatible machines, helping you stay prepared without sourcing parts individually.

Compatibility & installation tips

Before ordering, double-check your engine model and part number to confirm a proper match. If your manual lists NGK CMR6H or STIHL equivalents, this plug aligns with those specs.
