I have a '76 550k and am looking into replacing the plug caps. Bike bandit has the caps (NGK's)....but like 15 different ones listed for "my bike". And conveniently doesn't list specs other than product code names. I've tried to research here and on ngk's site but can't seem to find the specifications for the ones I need, basically resistance I need and the angle. I'm almost positive I need the 130 degree angled ones?.... They have the OEM ones also but, they like $13 and $23 bucks each. Trying to save a little money here. Anybody got a clue on what I need they can throw at me!? Hopefully not the lead pipe in the living room by the butler.......hahha, sorry it was to easy to post a bad joke.
