Ignition Stick Coil for Yamaha WR 450 F, YZ 450 F and YFZ 450
Yamaha WR 450 F / YZ 450 F / YFZ 450 - 2003-2013 - OEM replacement 5TA-82310-00-00 - Part number RM06046
This is a brand new ignition stick coil for the Yamaha WR 450 F, YZ 450 F and YFZ 450, supplied as a direct replacement for the original unit. A stick coil is a one piece design in which the coil and the spark plug cap are combined into a single item that sits directly over the plug in the cylinder head well, rather than a separate coil feeding a plug lead. It is a neat and efficient arrangement, but it also means that when the cap end wears out the whole coil has to be replaced - which is exactly the situation this part is made for.
The unit is built to a standard that exceeds the original equipment, delivering an ultra high output spark and smooth engine operation, with efficient power transfer connections at both ends. On a hard worked 450 the stick coil sits in the hottest, dirtiest part of the engine and takes a constant beating from vibration, heat cycling and water ingress down the plug well, so a strong replacement is worth having. It is a direct fit: 118 mm long, 25 mm in diameter, with a single two pin plug matching the original connector. Every unit is tested before it is shipped.

Frequently Asked Questions
Will this fit without modification?
Yes. It is a direct replacement for the original stick coil, sharing the same 118 mm length, 25 mm diameter and single two pin connector, so it drops straight into the plug well and connects to the existing loom. Confirm before ordering that the number on your original unit is 5TA-82310-00-00 or 5TA-82310-10-00.
What is included?
The ignition stick coil itself. Because a stick coil integrates the spark plug cap into the coil body, there is no separate cap or HT lead to transfer over from the old unit - the one part covers both jobs. No additional hardware is required to fit it.
How do I know the old coil has failed?
Spark plug caps combined with coils do wear out, and on a stick coil the two fail together. Typical symptoms are hard starting, a weak or intermittent spark, a misfire that gets worse as the engine heats up, hesitation under throttle, or an engine that cuts out and then restarts once it has cooled. Cracks, tracking marks or corrosion visible on the coil body or around the cap end are further evidence.
What is the difference between a stick coil and an external coil?
An external coil is mounted away from the cylinder head and feeds the spark plug through a separate HT lead and cap. A stick coil, like this one, is a slim cylindrical unit that sits down inside the plug well with the cap built into its lower end, so the high tension path is as short as possible. That means fewer connections to corrode or break down, but it also means the coil and cap are replaced as one part.
