Some information from a helpful source at DENSO

Z50 4-Stroke

When I was still in my 'moped days' I drove a Honda C50 (Supercub)
It had a standard engine with standard 12mm carburettor and fixed ignition timing instead of the retarding ignition that is fitted to Dutch models to keep the power down. Installed the platinum U22FS-ZU to replace the C7HSA and I could clearly notice the difference. There was no more hesitation in medium to high rev's and the engine could pull cleanly to about 9800 rpm.
Below I made an overview of the high performance plugs.
