Common questions
How many spark plugs are included in this package?
This Accel High Performance Platinum Spark Plug product comes as a 2-pack, providing one plug for each cylinder of your V-twin engine.
Will these platinum spark plugs significantly improve my bike's horsepower?
Platinum spark plugs primarily offer more consistent spark and easier cold starts. While they contribute to overall engine efficiency, significant horsepower gains are typically seen when combined with other performance modifications like cam upgrades or exhaust systems.
How do platinum spark plugs compare to standard plugs in terms of lifespan?
Platinum tips are highly resistant to erosion, allowing them to maintain their proper gap much longer than standard copper plugs. This typically extends their service life, potentially by 25,000+ miles or more, depending on riding conditions and maintenance.
