The wire itself IS actually really good - though the boot is a total POS, you can get just a replacement boot from any lawnmower repair business or it's equivalent.

If you want to use a electronic speedometer or listen to a radio w/o interference - get a "resistor" cap, it doesn't hamper performance in any way - just kills the electromagnetic "noise".

I ran with the stock cap for about a week before it fell apart lol
