Filter Kit Mitsubishi GS16-GS25 & GS160-GS250 – S3L / S3L2 Engine

Description

Complete maintenance kit for the Mitsubishi GS Series compact tractors with the Mitsubishi S3L or S3L2 three-cylinder diesel engine. This kit fits two GS generations: the GS16-GS25 (production years ~2003-2005, 8+8 transmission) and its successor GS160-GS250 (~2006-2012). Both share the same S3L/S3L2 engine and therefore use the exact same filters. The kit contains the three filters you need for a full routine maintenance service: oil filter, fuel filter, and air filter. Carefully put together based on the original part numbers from the factory manual, ensuring a 1-to-1 fit.

✔️ Complete for one maintenance service — oil filter, fuel filter, and air filter in a single order
✔️ Exact OEM fit — based on original Mitsubishi part numbers from the GS manual
✔️ Suitable for both GS series (GS16-GS25 and GS160-GS250) with S3L/S3L2 engine
✔️ Premium quality filters from European suppliers — tested to manufacturer specifications

Kit contents:

• Engine oil filter — spin-on, M20×1.5 · Ø 67.5 mm · H 87 mm
• Fuel filter — element Ø 45 × H 54 mm, including large and small O-ring
• Air filter — Ø 85 × L 160-166 mm, inner Ø 45 mm

Maintenance intervals according to the manual: oil filter every 100 hours (first time 50 hours), fuel filter element every 200 hours, air filter check/clean every 100 hours and replace if damaged.

Note on name confusion: the type plate of both series shows designations such as 三菱GS16, GS18, GS20, GS21, GS21S, GS23, GS25, GS25S. The GS16-GS25 is the older series with an 8+8 transmission; the GS160-GS250 is the successor with a 12+12 transmission. Unsure about your model? Compare production year, number of gears, and the type plate.

Tip: replace all three filters at the same time during every service — a saturated fuel or air filter costs power and increases fuel consumption. Glow plugs are a common maintenance item on the Mitsubishi S3L/S3L2 — check them during the service as well. Want to know more about maintenance?
