⭐⭐⭐⭐⭐ “The Spark Plug That Lit a Fire Under My Engine (and My Expectations)”
You ever replace a spark plug and actually feel your soul ignite? No? Then you haven’t met the NGK Lazer Iridium—the plug so elite, it doesn’t start engines, it summons horsepower from the netherworld.Right out of the box, it radiates superiority. I mean, come on—Lazer? Iridium? This isn’t a spark plug, it’s a Marvel weapon disguised as engine tech. I half-expected Tony Stark to pop out and install it for me. But nope—just me, my wrench, and the sudden feeling that my ride was about to light up the world like Times Square on caffeine.Once installed? Instant combustion bliss. Cold starts? Now hotter than my ex’s temper. Throttle response? So crisp it deserves its own ASMR channel. Idle? Smoothed out like it just got a Swedish massage. My engine hasn’t felt this fired up since factory testing.Let’s not forget that iridium isn’t just a fancy name. This metal is rarer than a sincere tweet and tougher than a $2 steak. It laughs at wear, scoffs at carbon, and sparks joy (and combustion) like it’s on a mission from the ignition gods.Old plug? It’s in the trash now, right where it belongs—grounded for life. That thing used to “spark” but in a sad, wheezing birthday candle kind of way. The NGK? It ignited my faith in internal combustion. My engine now purrs like it just got a promotion.Bottom line: if you’re still running anything else, you’re shorting out your own joyride. This plug didn’t just complete the circuit—it set my whole driving experience ablaze. Five stars. Would spark again.

Excellent!
Bought for 2018 yamaha wolverine and it runs as good as new. Had noticed idling issues recently and decided to start troubleshooting at the plugs. Worked great!

Great replacement for NGK/LMAR8A-9 for 2019 Yamaha XMAX 300
Great replacement for the original (non-iridium) NGK/LMAR8A-9 for my 2019 Yamaha XMAX 300. The bike seems to start easier and rev faster/has more throttle response vs the old plug. Yes this iridium plug is a lot more expensive than most (probably the most expensive single spark plug I have ever purchased), but I would say it's worth it.

Replacement plug in my '20 Yamaha Wolverine X2 XT-R.
I'd rate them higher, but only used them for a short time so far.

Solid spark plug
I run these in my Yamaha 2020 Wolverine X2 Xt-r. Much better than the normal stock plugs. Just bought these to have an extra set when I change out the first ones.
