best spark plugs for 671 blower

The last time I wrestled with my 671 blower, I kept hitting snags with inconsistent starts and rough idling. It felt like I was pouring fuel into a fire that just wouldn’t catch.

That was until I swapped out the old spark plugs for these Champion Copper Plus CJ6s.

Right away, I noticed how easy they were to install—no fuss, just a clean fit that matched my blower’s manual perfectly. The copper core conducts heat really well, which helps prevent fouling and keeps the engine running smoothly.

I also appreciated the solid construction; these plugs feel durable and well-made, which is key for something exposed to the elements and vibration.

After a few uses, I saw a clear difference in how reliably my blower started. No more tug-of-war with the pull cord, and the engine idled steady even after hours of use.

The spark seems strong, providing consistent ignition and smoother operation overall. Plus, the two-pack is a smart buy—it saves me from scrambling for replacements mid-season.

Honestly, they’ve made my blower more dependable, saving me time and frustration on those chilly mornings. That said, it’s important to double-check your owner’s manual for the exact fit, since a wrong plug can still cause issues.

Still, for the price and performance, I’d say these are a solid upgrade for anyone tired of struggling with their blower’s ignition.
