MSD Super conductor Spark Plug Wire Set for LS V8 Engine (99-05) SpecificationsDesigned by MSD these high-performance spark plug wires from the Super Conductor range are specially adapted to GM Group pick-ups (Silverado Sierra Avalanche...) with 3rd generation LS engines produced between 1999 and 2005. These 8.5 mm diameter 28 cm long wires offer an incredibly low resistance of 40 to 50 ohms without electronic interference. The low resistance results in less loss in spark energy so more reaches the spark plug.Each wire comprises a copper alloy conductor wound extremely tightly around a central core impregnated with ferromagnetism to form a particularly effective barrier against electromagnetic interference (EMI). The outer sleeve enveloping the conductor uses an exclusive blend of silicone and synthetic materials for maximum resistance to heat abrasion and tearing. The terminals are double crimped for added safety.Compatible engine list :V8 496/8 1LV8 364/6 0LV8 325/5 3LV8 294/4 8L
