698754 Air Filter Tune Up Kit Fits for John Deere L120 L111 LA130 D140 D130 LA135 LA145 for Briggs and Stratton 499486 499486S 18-26 HP Intek V-Twins Lawn Mower Parts with AM125424 492932s Oil Filter

What It Is

This is a 3-piece tune-up kit for John Deere lawn tractors and select Briggs & Stratton Intek V-Twin engines (18-26 HP). It includes an air filter, oil filter, and spark plug (typically an RJ19LM or equivalent) to replace worn-out parts and restore engine performance.

Fitment & Compatibility

• Fits John Deere models: L120, L111, LA130, D140, D130, LA135, LA145, and others with Briggs & Stratton Intek V-Twins.
• Cross-references: Replaces OEM air filters AM125424, 499486, 499486S; oil filter 492932S.
• Engine requirement: Works only with Briggs & Stratton 18-26 HP V-Twin engines (not single-cylinder or older flatheads).
• What to check before buying: Confirm your engine’s model number (stamped on valve cover or cylinder shroud) and measure the air filter length (approx. 5.5” x 4.5” x 1.5” for standard Intek). If your mower uses a different spark plug gap (e.g., 0.030” vs. 0.040”), verify the included plug matches your spec.

Key Things to Know

• Installation difficulty: Easy, 10-15 minutes. Requires only a socket wrench (spark plug), screwdriver (air filter cover), and basic hand tools. No special skills needed.
• Quality note: Aftermarket, not OEM John Deere. Filters and plug are functional, but the air filter foam density may be slightly lower than genuine Briggs. Fine for seasonal use, but heavy-duty or dusty conditions may favor OEM.
• Common gotcha: The spark plug gap is pre-set, but always double-check with a gap tool before installing. Also, the oil filter may be slightly shorter than OEM—verify clearance in your filter housing.
• Value: At ~$20, this kit is cheaper than buying all three parts separately (often $35+ OEM). Good for a single-season refresh.

Should You Buy It

Buy this if you need a quick, budget-friendly tune-up for a John Deere lawn tractor with a Briggs Intek V-Twin and don’t mind aftermarket quality for standard home use. Skip it if you run in heavy dust, need OEM longevity, or have a non-Intek engine.
