I got my kits from marto motosports on ebay, it came with magneto, cdi, and coil, they were really good at answering my questions. I stuck with pure Polaris parts, I didn't even look for other brands, I don't even know if anyone makes them. If I remember right, the coils were the same, but their were different colored wires from the magneto to cdi. I can check tomorrow and see what the difference was, I should have all the old parts and an extra new kit incase. I figure I have to keep my ski's running for another 5 years to get my money out of them. I have over $6500 in them from letting friends borrow them.
