Denso Spark Plug (BP4HS)

The packaging included the exact OEM part number match, which made installation hassle-free. My cart runs noticeably smoother after swapping these in.

Fired right up on the first crank after swapping out the old plugs—the ceramic tip and electrode gap were exactly as spec'd for my cart. No misfires on the hills, and the part number matched the OEM listing perfectly. For the price, this is a solid, no-fuss replacement.

Brought my old golf cart back to life with this plug—the engine is purring smoothly now after being a little rough on startup. The ceramic insulator around the electrode looks well-made and should hold up fine.
