Premium fit for HRX2173 and HRX2174 engines

This Genuine Honda spark plug is engineered to meet the original specifications for the HRX2173HYA, HRX2173HZA, HRX2173VKA, HRX2174HYA, HRX2174HZA, HRX2174VKA, and HRX2174VLA mowers when used with frames within the MAGA-2020001 to MAGA-2369999 serial range.

What this spark plug delivers

Rugged construction and reliable ignition are hallmarks of Honda's OEM parts. This plug is designed to withstand typical mowing duties and varying weather, helping your mower start more consistently and run smoothly between service intervals.

  • Consistent starting in cool or damp conditions
  • Durable electrode design for longer service life under normal use
  • Precise heat range tuned for Honda HRX engines to support stable operation

Real-world benefits you might notice

In everyday mowing tasks, a genuine plug can contribute to a steadier engine rhythm, cleaner combustion, and less erratic idle. While results vary with maintenance and conditions, using the correct OEM part supports your mower’s original performance profile.

  • More predictable starts and steady power delivery
  • Better fuel efficiency and reduced engine hesitation over the mower deck
  • Ease of maintenance with readily available OEM replacement parts

Fit, installation, and care tips

To ensure compatibility, verify that your mower’s frame serial falls within MAGA-2020001 through MAGA-2369999 before ordering. For install: clean threads, snug the plug by hand, then torque per your service manual. Replacing with a genuine plug helps preserve fit and ignition timing.

Note: This is a genuine Honda part designed for specific HRX models. Always consult your owner’s manual or a qualified technician if you’re unsure about compatibility.

Why choose genuine Honda over aftermarket plugs?

OEM parts preserve factory fit, ignition spark performance, and overall reliability. While aftermarket options may be cheaper, using a genuine plug aligned to Honda's specs can help maintain the engine’s intended behavior and potential warranty considerations.

  • Exact thread size and heat range
  • Quality control aligned with Honda manufacturing standards
