Product Details
Aftermarket iridium-tip plug for riders who want quicker starts, sharper throttle response and longer service intervals than a copper plug.
- 0.6mm fine-wire iridium center electrode lowers the voltage required to fire, so cold starts and idle quality both improve.
- Iridium alloy resists erosion at high temperature, holding the gap longer than a standard copper-core plug.
- Tapered ground electrode reduces flame-front quenching for a more complete burn at part throttle.
- Trivalent metal plating on the housing resists corrosion and prevents seizing in the cylinder head.
- Sold individually — match the part number to your bike's plug call-out (see the variant title).
