Moroso Super HEI Ignition Kits

Upgrade your ignition system with Moroso Super HEI ignition kits! Developed for racing, all ignition components are engineered to improve ignition accuracy, fuel economy, starting and throttle response. The HEI distributor cap and rotor are precision molded from advanced polymers with solid brass contacts to provide high dielectric strength and unsurpassed timing accuracy. Custom-fit Blue Max spiral core wire set is factory terminated in the correct lengths with numbered I.D. tags, corrosion-resistant locking plug terminals and high-temperature silicone boots. The wire loom kit with separators and show-quality chrome brackets routes wires over the valve covers to keep them away from hot exhaust manifolds or headers. Kit includes HEI distributor cap and rotor, a coil cover, a Blue Max high-performance wire set, and super loom kit.

Denso Oxygen Sensors

Oxygen sensors, also known as Lambda sensors or O2 sensors, are among the most sensitive and critical components on your car's engine. They monitor the air/fuel mixture under idle, moderate acceleration, and cruise conditions. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio than the newer wide range air/fuel sensors (A/F sensors). Today's engines may use as many as four oxygen sensors to monitor exhaust gas oxygen content and catalytic converter efficiency. In order to perform these functions properly, Denso oxygen sensors adhere to strict OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt drivability and illuminate the check engine light, resulting in costly and time-consuming repairs. Denso First Time Fit oxygen sensors are designed to meet those tolerances and more. Key features and benefits of Denso Oxygen Sensors include: * Robotic laser welds * Porous PTFE filters block efficiency-robbing contaminants * Double-protection covers maintain proper temperature for quicker response times and protect ceramic elements from silicone and lead fouling * Rugged, watertight stainless steel housings resist corrosion and contamination * Aluminum oxide trap layers keep silicone and lead out, preventing damage to the platinum electrode * Refined zirconia elements improves sensor response * Superior design maximizes engine performance while reducing fuel consumption and harmful emissions * First Time Fit design delivers the right part the first time

PerTronix Flame-Thrower Race HEI Distributors

Flame-Thrower Race HEI distributors from PerTronix produce 42 percent more energy in the coil, with 46 percent faster spark breakdown time. This allows 48 percent more peak current to reach the spark plug, compared to their Street/Strip HEI distributors. That's an enormous improvement over stock HEIs and most aftermarket HEI distributors. A specially designed vacuum lockout mechanism prevents timing adjustments that change rotor phasing, adversely affecting the burn time and efficient fuel combustion. The rotor plates are TIG-welded to the mechanical advance mechanism, preventing high-rpm distortion and improving mechanical reliability. Each distributor uses a new aluminum housing cast and is machined from a strong, but lightweight A384 alloy. They're supplied with a high-dielectric strength cap with solid brass terminals, a balanced rotor, and a low-resistance center coil brush. Also included are nylon rotor hold-down screws and a factory-installed, high performance mechanical curve kit with precision-machined weights and a center plate. A hardened, machined steel gear is standard, along with an electronic module and coil combination that excels in the 6,000 to 8,500 rpm range. These distributors are great for both Circle Track and drag race applications where factory-type HEI distributors are mandated.

PerTronix Flame-Thrower HEI Distributors

Experts agree that HEI ignition performance relies on a quality module and coil. Pertronix believes the combination of a great module and a great coil makes their Flame-Thrower HEI distributors the best. They've engineered the module and coil to work together to provide you with superior ignition performance on the street or track. Compare the Flame-Thrower high performance module and coil to an original GM HEI distributor and you'll find these improvements: * Operates without misfires up to a minimum of 7,500 rpm, nearly 3,000 rpm higher than most enthusiasts report with their original HEI * Produces 67 percent more energy in the coil * Spark breakdown time (the amount of time until the spark plug has enough voltage to spark) is 45 percent faster, resulting in more accurate timing throughout the rpm range * Delivers twice the energy across the spark gap (during a one-millisecond burn time) * Spark duration and more energy to the spark allow wider plug gaps (.050 in.-.055 in.), increasing flame kernel growth These are dramatic improvements, not just because of a great module and coil, but also because they've been designed to work as a team to produce these results. Models and options are available for applications from the 1950s and up.
