Review on Denso 671 8183 Ignition Wire by Tommy Clement

This is a boot that attaches to a separate direct ignition spark plug coil. Each of the 8 boots also comes with a small spring and there is a lot of boot silicone in the set. Honestly, unless your boots are ripped or you just don't want to spend money trying to keep those boots looking like new when you get new exhaust wires. Plugs, they have no real added value and are probably just a mental thing that men like to switch and feel like they've done our truck some good.
