Alright folks, buckle up because today was one of those “beat my head against the wall” kinda days that finally ended with a win. I figured this Honda 754 part number thing out, and man, was it hiding its secrets! Gonna walk you through exactly how it went down.

The Confusion Hits Hard
So picture this: I needed a new spark plug for my old generator. Simple, right? Wrong. Every dang website lists this Honda 754 spark plug like it’s the holy grail. Shoved “Honda 754” into the search bar, hit enter, and boom – instant confusion. Some sites said it fit my generator. Others said lawn mowers. Some even said chainsaws! I was staring at this tiny metal part feeling totally lost. “What the heck does 754 actually fit?” I yelled at my screen. Nobody gave a straight answer. Frustration level? Maximum.
The Deep Dive Begins
Time to get hands-on. I grabbed the actual old plug out of the generator. Wiped off the grease and grime. Sure enough, stamped right on the ceramic body: “754“. Okay, so that’s definitely the number. But I needed proof beyond shady websites. Pulled out my generator’s dusty owner’s manual – the little book I’d ignored for years. Flipped like a madman to the parts section. Bingo! Listed right there: Spark Plug, Part Number: 754. Confirmed mine needed it. But that didn’t explain why the internet said it fit everything.
The “Ah-Ha!” Moment
Here’s where things clicked. I went digging for the spark plug manufacturer’s info. Turns out, that “754” isn’t Honda’s main part number! It’s almost like a shorthand everyone uses. The actual manufacturer code tells the real story. Here’s what this little beast ACTUALLY fits:
- Loads of small Honda engines. Think older generators (like mine), some mowers, and certain pumps.
- Needs specific heat range. It’s not a one-size-fits-all plug.
- Works ONLY where NGK BPR6ES is specified. That’s its real identity!
That last point? Total game changer. The “754” is tied directly to needing an NGK plug with that specific BPR6ES code. This plug doesn’t just magically fit every Honda ever made. It fits the engines designed to use that exact NGK plug. The “754” is Honda’s label for when that specific plug is required.
Finally, Putting it to Use
Armed with this, slapping that new “754” (aka NGK BPR6ES) plug into my generator felt amazing. It screwed in smooth, snugged down just right. Yanked the starter cord… choked a bit… then ROARED to life, running smoother than it had in months. That familiar rattle calmed right down. Pure mechanic satisfaction!

Big takeaway? That “754” number isn’t random magic. It means “go find an NGK BPR6ES spark plug for this specific old Honda engine.” Saves you buying the wrong thing. Spread the word!
