Some (not all) NAPA stores carry solid core plug wire (7 mm). It's amazingly cheap, something on the order of 10 cents per foot.
Are you talking about the boot for the spark plug end of the wire? OMC / BRP sells one as p/n 0581027 which comes with a spring insert, list price is under $4.
If you can get that stuff for ten cents a foot, I want the number of that place.![]()
Yeah - I pay 60 cents a foot at my local Johnnyrude dealer.
