This kit fits the Daihatsu Hijet Truck S100, S110, S120, S130. It carries three ignition coils and three NGK spark plugs sized for the EF-RS twin cam. Misfires, flat spots off idle, and a truck that cranks longer than it should usually trace back to spark, and on the EF-RS the coils and plugs are the whole story. One kit renews all of it.
Confirm your engine before you order
This part is engine-specific and fits the EF-RS (EFRS) engine only. Before ordering, find your VIN / data plate in the engine bay and confirm the line marked ENGINE reads EF-RS (EFRS). The photo below shows where to look.
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-RS (EFRS).

Frequently asked questions
Why does this engine take three ignition coils?
The EF is a three-cylinder engine, and this setup gives each cylinder its own coil. Replacing all three keeps the spark even instead of strong on one hole and weak on the next.
How often should ignition parts be replaced?
Spark plugs are due about every 30,000 km. The coils have no schedule of their own. Typical life is 130,000 to 190,000 km, or eight to twelve years, so check them whenever the plugs come out and replace any that run weak.
Do I need special tools to install this?
Ordinary hand tools handle it. Use a plug socket with the rubber insert so the porcelain survives, and put a little dielectric grease in each boot to keep water out.

Not only was it a perfect fit and got my car running again, but during the process of removing it i had broken a piece and was able to send them a text where they responded with a link to order that part. Price may seem high to some of you guys but it is well worth it, it shipped fast and is also the only place to get one without importing.
Nice, high quality exhaust. I like it quite a lot overall. Install was quick and easy, bolted right in, and I was pleasantly surprised that it included a new flange gasket. It's a bit louder than expected, but the sound is good.
Received key blank in a timely manner , had it professionally cut to ensure proper fitment , tried it on the truck anywhere a key is required and ... 'bingo' perfect .
