GM HEI Distributor Tune Up Kit Black Cap

The PROFORM GM HEI Distributor Tune Up Kit Black Cap is an essential maintenance solution designed for General Motors vehicles equipped with High Energy Ignition systems. This comprehensive kit is perfect for both classic Chevy enthusiasts and those restoring ignition reliability in street machines. It addresses critical components that impact engine starting, idle quality, and overall combustion timing.

The black cap design not only integrates seamlessly with factory and aftermarket ignition setups but also resists UV degradation and weathering, which protects internal contacts from oxidation and moisture intrusion. This is crucial for preventing misfires and hard starting in older ignition systems. PROFORM's engineered tolerances ensure precise spark timing, which is vital for maintaining consistent air-fuel ratios across varying engine loads and RPM ranges.

Mechanics and engine builders working on second-generation and later small-block Chevys, big-blocks, and inline sixes will find this kit compatible with both carbureted and fuel-injected applications. The kit consolidates all necessary wear items and adjustment hardware, making it a convenient addition to any serious builder's or weekend mechanic's toolkit.
