Ordered this OEM 2-pack of Champion spark plugs (Kohler 25 132 23-S / 2513223S) for my Kohler Command K OHV 7000 series (KT725) engine, and let me tell you—these little lightning bolts mean business. Installation? Easier than pretending I’ll read the whole owner’s manual. Pulled the old plugs, threaded these pre-gapped beauties in, torqued appropriately, reconnected, and boom—instant ignition enthusiasm. The engine fired up like it had just downed a double espresso. It’s still too early in the season to mow, but I couldn’t resist a test run. Converted the tractor mower into a full-blown leaf-blasting machine and sent it down my 1/10-mile driveway like a suburban hurricane. Leaves scattered. Neighbors stared. Power was smooth, responsive, and downright smug. Idle is steady. Throttle response is crisp. No sputter, no hesitation—just clean, confident combustion. Exactly what you want from OEM-spec plugs. If your tractor’s been sounding like it’s negotiating with itself before starting, do it a favor. These plugs brought mine back to “runs like a champ”… which, given the name, feels poetically correct. Five stars. Lawn domination pending.
