Genuine OEM Honda (HRR2169PKA) (HRR2169VKA) (HRR2169VLA) (HRR2169VYA) (HRR216K9PKAA) (HRR216K9VKAA) (HRR216K9VLAA) (HRR216K9VYAA) Walk-Behind Lawn Mower Engines Spark Plug

What It Is

This is a Genuine OEM Honda spark plug designed specifically for Honda HRR2169PKA, HRR2169VKA, HRR2169VLA, HRR2169VYA, HRR216K9PKAA, HRR216K9VKAA, HRR216K9VLAA, and HRR216K9VYAA walk-behind mowers. It ensures proper ignition for 160cc-190cc Honda GCV engines used in residential lawn care.

Fitment & Compatibility

Before buying, confirm your mower’s model number matches one of the eight listed above (check under the seat or on the engine shroud). This is a direct OEM replacement—no adapters or modifications needed. The spark plug gap is pre-set to 0.028-0.031 inches (0.7-0.8 mm), but verify with a feeler gauge before installation. Does not fit Honda engines with different plug threads (e.g., 14mm vs 12mm). If you have an aftermarket engine swap, measure thread length (19mm) and hex size (13/16″).

Key Things to Know

• OEM vs Aftermarket: Genuine Honda ensures correct heat range and electrode material; cheap plugs may cause misfires or hard starts.
• Installation: Easy with a socket wrench and spark plug socket; avoid overtightening (torque to 15-20 ft-lbs). No special tools needed.
• Common Gotcha: Old plugs can carbon-foul if engine runs rich—replace annually or after 100 hours of use. Check for cracked porcelain before installing.
• Quality: Copper-core electrode provides reliable spark, but it’s not iridium—expect 1-2 seasons of normal use.

Should You Buy It

Buy this if you own one of the listed Honda HRR216 mowers and need a drop-in, factory-spec replacement for routine maintenance. It’s the right choice for reliability and simplicity, especially if you avoid aftermarket guesswork. Skip it only if you’ve upgraded to a high-performance ignition system requiring a different plug.
