I bought some iridium plugs not really thinking about the ends. Well I got them and they don't fit. They have the clip end instead of the screw end. So my question is do they make them with the threaded end, otherwise what would I need to do to make them work.
 
well that's a bummer. i have an NGK replacement spark plug boot and it uses that style of spark plug end.
 
Guess I'll send the good one back and see if I can find the other end or at least one you can take the adapter piece off of. where did you get the boot and how much did it cost?
 
i can't remember cost, it was like 6 bucks? i got it at the local dealership, they said its actually for a snowmobile but its nice and watertight, and grips the plug better so it won't vibrate loose as easily
 
yeah that is aftermarket they come with a solid black rubber one and the NGK I replaced mine with takes the screw too. I just ordered some iridum plugs from (rockymountainatv.com) they should be here today I'll let you know if they screw off or not. That sucks you broke one trying. really hope mine unscrew
