What It Is

This tune-up kit bundles genuine Honda oil (08207-10W30), oil filter (15400-PLM-A02), air filter (17210-Z6L-010), two spark plugs (98079-5587G), and a fuel filter for the GX630, GX660, and GX690 engines. It’s designed for one complete service on commercial mowers, generators, or pumps using those engines.

Fitment & Compatibility

• Engine models only: GX630, GX660, GX690. Not for GX610, GX620, or GX390.
• OEM part cross: Oil filter replaces Honda 15400-PLM-A02; air filter replaces 17210-Z6L-010; spark plugs replace 98079-5587G (NGK BPR6ES or equivalent).
• Oil type: 10W-30, 1.1 qt (1 L) bottle – GX630/GX660 take ~1.6 qt, GX690 takes ~1.8 qt. You’ll need a second bottle for a full fill.
• Check your mower deck: No deck size limit, but verify your mower brand (e.g., Toro, Exmark, Gravely) uses these specific Honda engines.

Key Things to Know

• Genuine Honda parts: Oil, filter, and spark plugs are OEM; air filter and fuel filter are aftermarket but match Honda specs. Quality is high for the price.
• Installation difficulty: Easy (30-45 min) – drain oil, swap filter, plugs, air filter, and fuel filter. No special tools needed beyond a spark plug socket and oil filter wrench.
• Common gotcha: The kit includes only two spark plugs – GX690 has three cylinders, so you’ll need to buy a third separately.
• Fuel filter: Hard to access on some mower frames – plan to remove the fuel line clamp carefully to avoid leaks.

Should You Buy It

Buy it if you have a GX630, GX660, or GX690 engine and want a single, well-priced kit for a full service. It’s ideal for DIY owners who want genuine oil and filter quality without sourcing each part separately. Skip it if you need three spark plugs or prefer all-OEM air/fuel filters.
