Includes OEM wire set (not some cheaper off brand that won't hold up at 500whp), Cap, Rotor, and 2 sets of NGK BKR7E spark plugs. Why 2 sets of plugs? Well, they wear out faster than the rest of the ignition system and need to be replaced more often. If you are not sure which wire set you need: '91-92 Wires are a friction fit to the cap (as shown in picture), while 93+ wires have a retainer clip on each wire (similiar to the coil wire connector shown in the picture).
