Best Spark Plug for Honda Snow Blower Buying Guide
Compatibility with Honda Engine Models
Honda snow blowers use a range of small engines, including GCV160, GCV190, HS520, and HS55 series. Each engine requires a specific spark plug thread size, reach, and heat range.
Always check your owner’s manual or the existing plug’s part number before buying. For example, the Honda 98079-55846 (NGK BPR5ES) is common in many GCV engines, while the 98079-56846 (NGK BPR6ES) suits hotter-running models.
Using the wrong plug can cause misfires or engine damage.
Aftermarket plugs often list compatible Honda models, but OEM Honda or NGK plugs guarantee fitment. If you own a gas snow blower with a Honda engine, matching the exact OEM part number avoids start-up issues in cold weather.
Heat Range and Electrode Material
Heat range determines how quickly the spark plug dissipates heat. A plug that is too cold (e.g., BPR6ES) is better for sustained high-load operation, while a hotter plug (BPR5ES) helps prevent fouling during short, cold starts.
For most Honda snow blowers used in intermittent winter duty, a medium heat range like BPR5ES or BPR6ES works well.
Electrode material also matters: copper core plugs offer reliable conductivity and low cost, while iridium or platinum versions last longer but are rarely needed for seasonal equipment.
Our research shows that snow blowers used on asphalt driveways often run at moderate temperatures, making copper plugs a cost-effective choice. If your machine sees heavy use, consider a plug with a slightly colder heat range to prevent pre-ignition.
OEM vs. Aftermarket Spark Plugs
OEM Honda spark plugs are manufactured by NGK and branded with Honda part numbers. They offer guaranteed compatibility and quality control. Aftermarket plugs from brands like Champion, Torch, or generic suppliers can save money but may vary in construction.
Verified buyer feedback indicates that OEM plugs (e.g., Honda 98079-55846) consistently deliver reliable starts, while some aftermarket options have reported fitment or durability issues.
For a large driveway snow blower that you depend on, sticking with OEM or reputable NGK plugs minimizes risk. For budget-conscious owners, high-rated aftermarket options like the B0G5Y244CH 5-pack provide excellent value without sacrificing performance.
Ease of Installation and Maintenance
Replacing a spark plug on a Honda snow blower is straightforward: remove the boot, unscrew the old plug, gap the new one to spec (typically 0.028, 0.031 inches), and tighten by hand plus a quarter turn.
Most plugs come pre-gapped, but always verify. A good spark plug should last one to two seasons with proper maintenance. Check the plug annually before winter and replace if the electrode is worn or the insulator is cracked.
If you’re also shopping for two-stage snow blowers, the same spark plug care applies. Keeping a spare plug in your toolkit ensures you’re never stuck with a no-start on a snowy morning.

Frequently Asked Questions
What spark plug does a Honda HS520 snow blower use?
The Honda HS520 typically uses a Champion RN12YC or NGK BPR5ES spark plug. The OEM part number is 98079-55846. Always verify by checking the plug currently installed or your owner’s manual.
Can I use an NGK BPR6ES in my Honda snow blower?
Yes, if your engine is designed for a BPR6ES (colder heat range). Many Honda GCV160 and GCV190 engines use the BPR6ES (98079-56846).
Using a BPR5ES (hotter) in an engine that calls for BPR6ES may cause pre-ignition, while using BPR6ES in a BPR5ES engine can lead to fouling. Check your manual.
How often should I replace the spark plug in my Honda snow blower?
Replace the spark plug annually or every 100 hours of operation, whichever comes first. In snowy climates where the machine sits for months, a fresh plug each season ensures reliable starting. Inspect the plug for wear, carbon buildup, or cracks before each winter.
Are aftermarket spark plugs as good as OEM for Honda snow blowers?
High-quality aftermarket plugs from reputable brands like NGK (non-OEM packaging) or Champion can perform equally well. However, some generic no-name plugs have reported poor fitment or shorter lifespan.
Our top-rated aftermarket option, the B0G5Y244CH 5-pack, has excellent buyer feedback. For peace of mind, stick with OEM or NGK.
What gap should I set for a Honda snow blower spark plug?
Most Honda small engines require a gap of 0.028 to 0.031 inches (0.7, 0.8 mm). Always confirm in your owner’s manual. Many plugs come pre-gapped, but it’s best to check with a feeler gauge before installation.
