This part is engine-specific and fits the EF-GZ (EFGZ) or EF-ZS (EFZS) engine only. Before ordering, find your VIN / data plate in the engine bay and confirm the line marked ENGINE reads EF-GZ (EFGZ) or EF-ZS (EFZS). 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-GZ (EFGZ) or EF-ZS (EFZS).

Frequently Asked Questions
How often should the oil and filter be changed?
Every 10,000 km (about 6,250 miles) or every six months, whichever comes first. Run 5W-30 if your winters are cold, 10W-30 if they are not.
Should I replace the air filter more often if I drive on dust or gravel?
Yes. A truck that works on gravel or around a farm clogs its filter far faster than one on pavement. Pull it at every oil change and look. If light barely passes through it, it is done. Most trucks land somewhere between six and twelve months.
How often is the fuel filter due?
About every 40,000 km (25,000 miles). No record of the last one? Fit this now and count from today.

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.
