Filter set Mitsubishi GS16-GS25 & GS160-GS250 – S3L / S3L2 engine

Description

Complete service set for the Mitsubishi GS-series compact tractors with the Mitsubishi S3L or S3L2 three-cylinder diesel engine. This set fits two GS generations: the GS16-GS25 (built ~2003-2005, 8+8 gearbox) and its successor the GS160-GS250 (~2006-2012). Both share the same S3L/S3L2 engine and therefore exactly the same filters. Carefully compiled from the original part numbers in the factory manual for a 1-to-1 fit.

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

Set 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

Service intervals (per the manual): oil filter every 100 h (first time 50 h), fuel filter element every 200 h, air filter check/clean every 100 h and replace if damaged.

Suitable for:

Mitsubishi GS16-GS25 (2003-2005, 8+8 gearbox)

• GS16, GS18, GS20 (S3L, 16/18/20 hp)
• GS21, GS21S (S3L2, 21 hp)
• GS23, GS25, GS25S (S3L2, 23/25 hp)

Mitsubishi GS160-GS250 (successor, 2006-2012)

• GS160, GS160S (S3L, 16 hp)
• GS180, GS200 (S3L, 18/20 hp)
• GS210, GS210S, GS210W (S3L2, 21 hp)
• GS230, GS250, GS250S (S3L2, 23/25 hp)
• Including the PAC, JAC and MAC versions

Mind the name confusion: the data plate of both series shows markings such as 三菱GS16, GS18, GS20, GS21, GS21S, GS23, GS25, GS25S. The GS16-GS25 is the older 8+8 series; the GS160-GS250 is the successor with a 12+12 gearbox. In doubt, compare year, number of gears and the data plate.

Mitsubishi engine

• S3L (1,125 cc): S3L-16A/17A/18A (GS16-GS20) · S3L-19A/20A/21A (GS160-GS200)
• S3L2 (1,318 cc): S3L2-14A/15A/16A (GS21-GS25) · S3L2-17A/18A/19A (GS210-GS250)

OEM reference:

• 31A40-02100, 30A4000100 – engine oil filter
• 31A62-00317 – fuel filter element · 31A62-00300 – fuel filter assy · 31A62-00318 / 31A62-00319 – O-rings
• 3546-0501-800 – air filter element · 67980-5820, 67980-8263-0 – air filter (alt) · 6A320-59930 – fuel filter (Kubota ref)

Tip: replace all three filters at every service — a saturated fuel or air filter costs power and raises fuel consumption. On the Mitsubishi S3L/S3L2 the glow plugs are a common service point — check them too.
