Confirm your engine before you order
This part is engine-specific and fits the EF-NS (EFNS) or EF-ES (EFES) or EF-GS (EFGS) engine only. Before ordering, find your VIN / data plate in the engine bay and confirm the line marked ENGINE reads EF-NS (EFNS) or EF-ES (EFES) or EF-GS (EFGS). 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-NS (EFNS) or EF-ES (EFES) or EF-GS (EFGS).
Vehicle Fitment & Compatibility
The Hijet ran several engines in this era. Confirm your engine code on the VIN plate above, not just the chassis, against the table below.

Oiwa Garage Tech Note
"If you run dusty back-roads, check the element more often than the book says - a choked filter quietly eats power and economy."
Frequently Asked Questions
How do I know if I have the EF-NS (EFNS) or EF-ES (EFES) or EF-GS (EFGS) engine?
Check the VIN / data plate in the engine bay - the line marked ENGINE shows your code (the example plate above reads EF-NS; yours must read EF-NS (EFNS) or EF-ES (EFES) or EF-GS (EFGS)). This part fits the EF-NS (EFNS) or EF-ES (EFES) or EF-GS (EFGS) engine only, so confirm the code before ordering.
Can I just clean and reuse the old one?
Tap out loose dust in a pinch, but a paper element that is oil-soaked or collapsed should be replaced - a choked filter quietly eats power and economy.
How often should I replace it?
On the factory interval, or sooner if you drive dusty roads - it is a cheap part that protects an expensive engine.

I'm very happy with the exhaust. It sounds great. I was juggling between this one and Special K's behind the bumper exhaust and I ultimately decided on this one. Installation was easy and the only thing I would recommend is getting some washers because the holes on the flange for the growler are ovaled out to allow for adjusting the fitment. Without the washers the flange nuts were just a bit to small.
I buy almost all of my Honda Acty product through OIWA's website and have never had a complaint. I would highly recommend OIWA's website for any kei truck products.
