Everything needed for a professional-quality oil and basic tune-up service on 1988–2000 Honda TRX 300 ATVs in one genuine Honda parts kit.

This factory-sourced service kit bundles the exact items Honda designed for the TRX300's maintenance intervals: three quarts of GN4 10W-40 motor oil, an OEM oil filter, OEM air filter, a spark plug, a crush washer, and a disposable funnel. The components are matched to the engine’s requirements so you can complete a clean, reliable oil change and basic tune-up without hunting down separate parts.

What parts are included and why they matter?

The kit contains genuine Honda components chosen to work together for proper lubrication, filtration, and ignition. Using OEM parts reduces the risk of fitment issues and helps maintain consistent performance between services.

• Three quarts Honda GN4 10W-40 (part 08C35-A141M01) — correct viscosity and additives for TRX300 engines.
• Honda oil filter (15412-HM5-A10) — traps sludge and particles to protect bearings and rings.
• Honda air filter (17254-HC5-900) — prevents dust and debris from entering the intake.
• Spark plug — restores reliable spark and efficient combustion.
• Crush washer — ensures a leak-free oil drain plug seal.
• Disposable funnel — simplifies pouring oil without spills.

How does this kit fit the 1988–2000 TRX300 models?

Honda designed each part to the original equipment specifications for TRX300 model years 1988–2000. Fitment reduces the risk of incompatibilities common with aftermarket alternatives and streamlines the service process.

• OEM part numbers match factory service manuals for TRX300 model years.
• Oil viscosity selected for typical ATV operating conditions and engine clearances.
• Filter dimensions and sealing surfaces conform to factory tolerances.
• Spark plug type chosen to suit stock ignition settings.

What tools and steps are needed to perform the oil change and tune-up?

Basic hand tools and a safe workspace are all that's required. The kit gives the consumables — you'll only need a wrench for the drain plug, a torque wrench or careful hand tightening for the oil filter and drain plug, pliers or socket for the spark plug, and something to lift or level the ATV safely.

• Tools: 17mm/19mm wrench (drain plug), oil filter wrench, spark plug socket, funnel (included), rags.
• Steps: warm engine, drain oil, replace crush washer, install new filter, refill with three quarts, replace air filter and spark plug per manual.
• Tip: check owner's manual for torque specs and recommended service intervals.

Will using this kit affect warranty or future resale?

Installing genuine Honda parts for routine maintenance supports proper service history and reduces the chance of warranty disputes tied to improper parts. Clean, documented maintenance with OEM components is also a positive factor for resale value.

• Genuine parts align with factory recommendations and service records.
• Properly performed maintenance can help demonstrate care to buyers.
• Keep receipts and note dates/mileages to strengthen service documentation.
