WIX, NAPA, Gates, and Beck Arnley equivalents for filters, ignition, timing belt, and brakes.
OEM Daihatsu parts are still available for specialty items, but for consumables the USDM cross-references below keep costs low and parts on the shelf. Avoid generic Fram air and fuel filters for this application — dimensional mismatches are common. WIX and NAPA Gold are the reliable choices.
Engine Oil Filter
OEM Part Number
15601-87204
Thread
M20 × 1.5 mm
Bypass Valve
13 – 19 PSI
Warning:The bypass valve pressure matters. A filter with too-low bypass pressure stays open during cold starts and circulates unfiltered oil through the bearings. Stick to the verified part numbers below.

Fuel Filter (In-Line)
OEM Part Number
23300-87502
Danger:Remove the fuel pump relay before disconnecting fuel lines. Depressurize the system first — atomized fuel spray is an extreme fire hazard.
The carbureted EF-NS and EF-GS use a dual-vent distributor cap marked internally as ID#388 (029120-388). OEM cap number 19101-87220 (superseded by 19101-87504), OEM rotor 19102-87208. Always replace cap and rotor together — a dirty or pitted rotor causes erratic spark and hesitation regardless of cap condition.

Timing Belt
Danger:The EF-series is an interference engine. A timing belt failure causes the pistons to contact the valves — the engine will be destroyed. This is not optional maintenance.
