When I bought my GTP, first thing I replaced was spark plugs and wires. I replaced the wires with the AC Delco OEM option. I must have taken the wires off and put them back on a million times, always switching between stock, 104's, 605's, 606's all trying different tuning and spark plug combinations I could think of and scanning to see the results. I wasn't even gentle removing the wires, and they never broke on me. I could even get away with yanking on the wire itself.
Fast forward, bought a set for my Impala SS.... seriously, if they have been on for more than a couple weeks, forget about removing them. Spin the boot around, squeeze the boot firmly, pull.... the whole boot and wire come off, the connector stays on the plug... and this is every single wire. I had even used a ton of dielectric grease during the initial install anticipating having to remove them!
Then I had the same problem with a replacement set... was there a manufacturing change somewhere down the line? Maybe I need to switch brands?
