Summit Racing™ Premium EFI Intake Manifolds

Stock intake manifolds in electronic fuel injection vehicles often fall short of lasting for the life of the vehicle. Being molded from polymers they tend to warp or crack and start leaking vacuum or coolant over the years. Summit Racing™ Premium EFI intakes are just what you need when it's time to replace your manifold as our design improvements address the failures that occur with existing manifolds for this application on the market today. These units are made to fit your specific vehicle and come complete with the necessary hardware for an easy OE type installation. Make this the last manifold you ever buy for your car or truck. Check out these features and benefits below: • Made in USA by OE Tier 1 Supplier • Aluminum crossover design improvement to mount direct to the cylinder head eliminating coolant exposure and eventual failure at the plastic interface of existing manifolds on the market. • High grade coolant resistant material used in coolant fitting and block out locations to coolant system. All coolant exposure areas are addressed with appropriate material. • Heat staked inserts for coil mounting. • Includes alternator brackets, throttle body adapter (application specific), thermostat, gaskets or O-ring seals, and mounting hardware.

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.

MSD Ford Blaster Coil-on-Plug Ignition Coil Packs

These MSD Ford Blaster Coil-on-Plug ignition coil packs feature a patented winding design and direct bolt-in replacement. The improved spark energy and voltage of the coil packs, combined with their reliability, have made them a favorite of performance enthusiasts. They are designed as direct bolt-in replacement coils for many SOHC Ford V8 modular engines. The housing and installation are the same as the factory coils, but that is where the similarity ends. Inside the MSD coil packs, engineers used better quality materials to assemble the primary and secondary windings. The MSD Ford Blaster Coil-on-Plug ignition coil packs take the spark energy right out of the coil and put it across the plug gap to improve the combustion and output of the engine.

Coker Classic Star Series Whitewall Tires

Coker Classic Star Series Whitewall tires are modern radials with best-in-class speed, load and traction ratings. They feature stylish whitewalls, which are built into the tires from Day One—delivering the perfect look for your classic car. The whitewalls fit many American and European classic cars from the 1960 and earlier. Star Series tire ratings help them to provide excellent treadwear, traction, and temperature control. Another best-in-class rating is the T speed rating (118 mph), as well as XL load rating, thanks to a reinforced sidewall. The low-noise tread looks and performs nicely; and these tires are DOT approved and E-marked for the European market. You won't find a better whitewall radial tire on the market! * Best-in-class traction: Star Series tires feature Grade-A traction and temperature ratings, meaning you can expect excellent handling and traction on wet and dry roads. They're engineered to outperform all other whitewall tires, and feature a 480 AA UTQG rating for long-lasting tread life and unbeatable traction. This makes your classic car safer to drive in all weather conditions and improves your driving experience. * Star Series tires are engineered with a reinforced sidewall to better support the weight of classic cars. This reinforcement gives the tire Extra Load (XL) rating, meaning added safety and a long-lasting sidewall that won't break down over time. * Star Series tires feature a genuine wide whitewall sidewall style. This means that the bright white rubber is added directly to the tire sidewall during initial construction of the carcass, resulting in a truly integrated, high-quality product after vulcanization. Wide whitewall tires were a very popular choice from the 1930s through the end of the 1950s, and were eventually phased out of mainstream production by 1962. Originally, wide whitewall tires featured a bias ply construction, but now Coker Tire offers them in original style bias ply and modern radial construction. * T Speed rated: Up to 118 mph (190 km/h). Often required OE for higher performance trim level classic automobiles. * Available in a wide range of sizes

MSD Steel Distributor Gears

MSD's high-grade steel distributor gears are burnished for a smooth, scuff-free finish, and are machined for precise gear mesh. Excessive clearance causes timing fluctuation throughout the rpm range, resulting in lost horsepower, so MSD also designed these gears for tighter mesh between the camshaft and distributor drive gears.
