Built to exacting specifications, and extensively tested, ACDelco Auto Wires and Auto Cables includes our Original Equipment line for GM vehicles and a select offering of premium aftermarket Professional products for GM and non-GM vehicles. ACDelco Professional, premium aftermarket Direct Ignition Coil-on-Plug Boots seal snugly against the spark plug’s insulator, keeping moisture and contaminates out and promoting longer spark plug life. They are thoroughly engineered to meet or exceed your expectations for fit, form, and function. ACDelco Professional Direct Ignition Coil-on-Plug Boots provide the performance and dependability you expect from ACDelco.

Product Features:

• Weather tight boot seal for protection against moisture intrusion
• High temperature resistant silicone for protection against thermal overload
• Stainless steel internal spring with resistor to suppress RFI and deliver maximum voltage to the spark plug
• Premium, high-quality aftermarket spark plug boot Signs that you might need to replace your direct ignition coil-on-plug boot are:
• Engine will not start or run
• Reduced Power
• Excessive tailpipe emissions
• Check Engine Light is on
• Engine misfire
• Reduced fuel economy

The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 12 inch length of super conductor wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or choke. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.

Product Features:

• Bolt-on Performance
• Custom Fit For Make And Model Listed
• Wires Are Pre-Cut To Exact Specifications

ProConnect Wire

NGK Coil on Plug Boots are built to stringent OEM tolerances, combining original equipment fit, design and outstanding durability. NGK Coil on Plug Boots are manufactured using only premium silicone and always include any required internal springs and ferrite resistors for superior performance and RFI noise suppression. Bridging the important link between ignition coil and spark plug, COP boots should always be replaced with NGK Coil on Plug Boots at the time as changing spark plugs to prevent ignition problems such as flashover.

Product Features:

• PREMIUM GRADE SILICONE: Designed to withstand harsh environments
• OEM MATCHED: Includes all required internal springs and ferrite resistors for superior performance and RFI noise suppression

Ignition Wire Set
