NGK Spark Plug - CR7HSA - (10)

The NGK CR7HSA is a resistor-type spark plug designed for small-displacement motorcycles, scooters, and ATVs. This pack of ten suits workshops, fleet operators, and riders who prefer to keep service stock on hand.

NGK is a globally recognised manufacturer of ignition components, and the CR7HSA is among the most widely fitted plugs across a broad range of small-engine platforms. The built-in resistor suppresses radio frequency interference, making it the correct replacement for any machine that specifies a resistor plug in its service documentation.

• Resistor construction suppresses ignition noise and radio frequency interference
• 10 mm thread diameter with 12.7 mm thread reach
• 16 mm hex suits standard spark plug sockets
• Heat range 7 for broad compatibility across small-displacement engines
• Solid terminal with removable nut accommodates different HT cap styles
• Sold as a box of 10 — ideal for workshop or fleet servicing

• 10 x NGK CR7HSA spark plugs

Before installation, check and adjust the electrode gap to the specification in your vehicle's service manual — do not assume the factory-set gap is correct for your application.
Thread the plug in by hand first to avoid cross-threading before applying torque.
Tighten to the torque value stated in your vehicle's service manual; overtightening can strip the cylinder head threads or crack the ceramic insulator.
Use a correctly sized 16 mm spark plug socket — never use an impact driver to install or remove spark plugs.
If your engine manufacturer recommends it, apply a small amount of anti-seize compound to the threads before installation.
Pair with a resistor-type HT cap on machines that specify one; using a non-resistor cap with a resistor plug can affect ignition performance.
Inspect the plug at each scheduled service interval; replace rather than clean a heavily fouled, eroded, or damaged plug.
Store unused plugs in their original packaging in a cool, dry location to prevent moisture or contamination affecting the electrode gap or ceramic.
