MSD 8.5mm Super Conductor Spark Plug Wire Sets
MSD 8.5mm Super Conductor spark plug wire sets feature a special helically wound core that has just 40-50 ohms of resistance per foot—but with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire includes 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference "choke." This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. A tough, 8.5mm synthetic/silicone jacket over an extra-heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, dual crimp stainless steel terminals feature snap-locks to ensure a secure fit. Each set comes with clip-on cylinder markers for easy identification. MSD's 8.5mm Super Conductor wire sets are available in custom or universal-fit applications, assembled or not, with a variety of terminal and boot end options.

Summit Racing™ Extreme Performance Coated Brake Rotors
Summit Racing™ offers Extreme Performance coated brake rotors for thousands of vehicles, from the 1960s and up. They're manufactured on CNC machines using CAD-CAM design for perfect balance and alignment, then coated with silver zinc to resist corrosion. These rotors provide you with maximum stopping power, reduced warping, and longer life. The cross-drilled holes and slots provide an exit route for gasses and dust, resulting in better heat dissipation and less brake fade under hard use. Other solid-surface rotors allow gasses to create a cushion between the pad and the brake rotor, resulting in poor brake performance. The cross-drilled holes and slots clear away harmful gasses, restoring full pad-to-rotor contact. These coated rotors are a terrific performance upgrade when replacing your brakes. Order the model recommended for fitment on your vehicle.

MSD HEI Coils
MSD HEI coils increase spark energy when used with MSD HEI HEAT modules. Now you can replace your stock coil with these high-energy unitized coils for HEI distributors. They have low-inductance, high-temperature windings which charge the coil faster to give you increased spark energy at higher rpm. The premium epoxy filled construction is designed to withstand harsh race applications, as well as the wear and tear that daily usage dishes out, and still deliver more spark energy to the spark plugs.

PowerStop Performance Powdercoated Brake Calipers
PowerStop is on a mission to deliver an easy and affordable way for any driver to upgrade their brakes--no matter where or how they use their vehicle. PowerStop Performance powdercoated brake calipers are made specifically with the enthusiast in mind.

PowerStop calipers and the brackets are treated with an electrostatic high-temperature powdercoating. The easy-to-clean powdercoating helps to resist rust and corrosion, thus extending their life. They are 100 percent pressure-tested to verify piston operation and prevent any possible leaks from occurring, ensuring that every caliper is inspected for quality and safety. Calipers are expertly assembled using new pistons, seals, slide pins (where applicable), dust boots, bleeder screws, and stainless-steel brake pad abutment clips. High-temperature EPDM rubber dust boots and premium silicone lubricant are used for a smoother operation and an extended life in extreme conditions.

MagnaFlow Universal Catalytic Converters
MagnaFlow universal catalytic converters by Car Sound form the basic building blocks for many applications. The main benefit of universal catalytic converters is that one unit may cover a wide variety of vehicle makes and models. Installing universal converters often requires the use of welding, cutting, and tube-bending equipment that is readily available to most professional installers. They are extremely well made, with features such as: * A ribbed body that minimizes expansion and distortion when the converter heats up. They form a channel that protects the cushioning mat from direct exposure to exhaust gasses, and hold the ceramic catalyst in proper alignment. * A 1/2 in. lap joint where the necks meet the body. The neck does not extend into the converter body, where it could hamper exhaust flow. * Manufactured with separate dies on different sized inlets. Putting larger neck sizes on smaller bodies would reduce the flow of the converter and the quality of the product. * A monolithic honeycomb catalyst. The ceramic is designed for maximum flow and surface area. The coating method is strictly controlled to maintain exact specifications. * Seam-welded close to the converter body for a strong, tight bond. Welding along the edge could allow the converter to expand like the folds in an accordion, allowing the catalyst to move around. * Heavier-gauge stainless steel, tip-to-tip. They do not use inferior mixed weights and materials. * An aluminized or stainless OEM-style ribbed heat shield that creates a rigid wall of protection against heat and adds to the structural stability of the converter.
