I received 2 sets of boots each set has 10 boots in it. Wires already have boots that go to the plugs, I will have to make up the ends that go to the distributor. My question is one set of boots came with brass looking ends and the other set comes with silver looking ends. I tried placing one of each on the distributor and the silver looking ones fit a lot tighter than the brass ones, is there supposed to be a difference in the two? I would think that the brass ones would carry better current but not sure. Also the boots that came with the silver ends have numbers on then like 0022,0006 etc. Maybe be making way too much of this but kind of confusing to me. Sure would appreciate some help on this one. Thanks guys. | | | | | Joined: Feb 2004 Posts: 29,740 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,740 | Use whatever fits the best. A HEI coil develops a minimum of 50KV open circuit voltage, so a difference in material on the end of a wire will never have any practical effect on the performance of the system. Clean spark plugs with the proper gap fire at <10KV so you've got at least 5 times the voltage needed for a good spark at your disposal.
