Review on 🔥 NGK (7022) BPR6HS Standard Spark Plug (4): Efficient Ignition Boost for Optimal Performance by Jack Ford

Works great with the small Ford FG2200iS inverter generator (from Pulsar). My alternator isn't running 100% for other reasons, but I've decided to try a spark plug just in case. The factory installed spark plug initially had no gap (too small). Depending on your alternator brand, this may be a direct replacement with no clearance adjustment. I adjusted the gap on this new spark plug and had no luck. The generator sounds/works the same (not 100%). Only time will tell if they work well, but it's hard to tell as the alternator is already struggling. Ordered a few extras.
