This is a brand new ignition stick coil for the Kawasaki Ninja ZX-6R and ZX-6RR, supplied as a direct replacement to your original unit. On certain Kawasaki models the spark plug caps and the ignition coils are combined into one part, which reduces the number of components used and improves efficiency. The drawback is well known to owners: when the spark plug cap wears out, the cost of the replacement becomes more expensive, because you cannot renew the cap on its own - the coil goes with it. This unit gives you that replacement at a sensible price.
The quality exceeds the OEM equipment it replaces. It produces an ultra high output spark for smooth engine operation and uses efficient power transfer connections between the coil and the plug terminal. At 127 mm long, with a single connector carrying two pins, it matches the original in the plug well and at the loom, so fitting is a straight swap - lift out the old coil, unclip the connector, and push the new one home. No cutting, splicing or modification is required, and no separate plug cap or high-tension lead is involved.

Frequently Asked Questions
Does it need any modification to fit?
No. It is a direct replacement to your original unit. The 127 mm body and the single two-pin connector match the factory coil, so it drops into the plug well and clips onto the standard loom without cutting or splicing.
What is included?
One brand new ignition stick coil. The coil and spark plug cap are a single combined assembly, so there is no separate cap or high-tension lead to fit. This listing covers one coil - a four-cylinder ZX-6R needs one per cylinder.
How can I tell a stick coil has failed?
The usual signs are a misfire on one cylinder, an uneven idle, hesitation or a flat spot under acceleration, and hard starting that gets worse when the engine is hot. Moving the suspect coil to a different cylinder and seeing the misfire move with it is the quickest way to confirm the diagnosis. Cracks, burn marks or tracking on the body of the coil are grounds for immediate replacement.
My spark plug cap is worn but the coil seems fine - can I just replace the cap?
Not on this design. Kawasaki combined the cap and the coil into one part to reduce the number of components used and improve efficiency, so when the cap wears out the complete stick coil has to be renewed. That is precisely why an aftermarket replacement of this quality is worth having.
