So I went to pull off the spark plug wires to change out the 80K plugs originally in there and the wire, boot, heatshield, and coil shaped spring came off, but not the spade shaped connector because it was stuck on the plug. Is this normal, is the connector supposed to separate like that ? Can I just remove the connector from the plug, replace the plug, and then put the connector back on the plug then put the wire assembly pushed back on ? I noticed the heatshield has that spring in there, why ? Should I just fork out some more cash for a new set of wires and should I re-use those heatshields ? What brands of plug wires do you recommend ? I have the Bosch Platinum +2 plugs, what are your opinions of those ? Any help would be great, Thanks.
