Honda GX160
4-Stroke
The Honda GX160 is a 163cc 4-stroke overhead-valve engine and the most widely used model in the GX series globally, powering pressure washers, generators, water pumps, compaction equipment, and go-karts across residential and commercial applications. It uses a Keihin float-type carburetor and accepts NGK BPR6ES or Champion RC12YC spark plugs. The 4-stroke overhead-valve design delivers exceptional fuel economy and longevity. Routine maintenance every 100 hours includes oil change (SAE 10W-30), air filter cleaning or replacement, and spark plug inspection. The GX160 superseded the Honda GX140.
