Bosch Start (Copper) Spark Plugs — Motorcycle are dependable, standard duty ignition components engineered to meet the performance and reliability requirements of a wide range of two wheel engines. Built to the same high quality standards as Bosch original equipment (OE) parts, these spark plugs deliver consistent combustion and smooth engine operation for everyday riding conditions.

Key Features & Benefits:

• Copper Core with Nickel Alloy Electrode: Combines a copper centre core (excellent heat conductivity) with a nickel alloy ground electrode for reliable spark generation and efficient combustion.
• Reliable Cold Starting: Designed to produce a strong spark even when the engine is cold, supporting reliable starts.
• Corrosion & Seizure Protection: Nickel plated threads and shell resist corrosion and seizing in the cylinder head, simplifying installation and removal without needing anti seize compounds.
• Hassle Free Service: Factory preset electrode gap eliminates guesswork during replacement and helps maintain proper ignition performance over time.
• Heat Shrink Assembly: Ensures gas tight insulation and stable performance across normal engine operating temperatures.

Typical Application:

Bosch Start spark plugs are ideal for everyday motorcycle use — particularly commuters, standard bikes, and other street bikes that don’t require high end performance electrodes. They offer a strong balance of durability, ignition reliability, and value — perfect for routine maintenance and replacement intervals.
