I have an 83 polaris snowmobile. The spark plug caps are broken. Is there any way for me to replace these. There is a black box on the side (I'm not sure what it is called), were the spark plug wires come out of. The wires have pulled out of the box and so I pushed them back in a scyliconed around it to keep them coming out. Is there a better way to fix this? or should I just buy a new part? How much do they cost? and is there a good online website to order from? no exactly what it is called would be helpful too.
