Confirm your engine before you order

This part is engine-specific and fits the EF-NS (EFNS) engine only. Before ordering, find your VIN / data plate in the engine bay and confirm the line marked ENGINE reads EF-NS (EFNS). The photo below shows where to look.

Example Daihatsu Hijet VIN data plate showing the EF-NS (EFNS) 659cc engine code on the ENGINE line, chassis S100P. Example only - check your own plate to confirm your engine before ordering. — Example plate shown is an **EF-NS** engine (chassis S100P, 659cc). Yours shows your own code on the same ENGINE line - for this part it must read **EF-NS (EFNS)**.
