The C7HSA is a replacement spark plug for GY6 scooter engines, and it is used on small motorcycles, ATVs and outboards as well. It has a white ceramic insulator, a silver hex body, a short threaded shank and a bent ground electrode. The catalog number is 4629, and Z9Y is a cross reference seen in some parts stores; if your old plug carries that marking, it is the same part. The C6HSA and CR7HSA from the same family look close but differ in heat range and resistor setup, so they are not direct substitutes; compare the markings and thread of the old plug, or send a photo when unsure. Replace the plug when the electrode is caked in carbon, the spark runs weak, cold starts drag, or the exhaust smells of raw fuel.
FAQ
Q1: What is the C7HSA spark plug?
A standard plug for GY6 scooter engines, catalog number 4629, also used on small motorcycles, ATVs and outboards.
Q2: How do I know my spark plug needs replacing?
An electrode caked in black soot and a misfire under load, a hard cold start with a raw fuel smell and worse economy, or white deposits on the insulator all point to a plug that should go.
Q3: Is the C7HSA the same as the C6HSA or CR7HSA?
They look close, but they differ in heat range and resistor setup, so they are not direct substitutes. Compare the markings and thread of your old plug, or send a photo before ordering.
