In this category you will find all the spark plugs we can have for your motocross GAS GAS EC 250cc 450cc 4 stroke. We work mainly with the brand NGK which offers a wide range of excellent quality products. Original type spark plugs but also competition type spark plugs like iridium, palladium,... Having a spark plug adapted to your engine is essential. A cold spark plug will have less risk of piercing your piston in case of high demand. An iridium spark plug gives a finer but more intense spark. This will make your engine burn better but they are also more fragile over time.

We advise for the maintenance of your motorcycle cross a change of spark plug every 40 hours or 10 000 km depending on the use of your engine
