The GMC K25 1975-1978 DR-450 Streak Ignition Distributor Cap is a crucial component of the ignition system in certain GMC engines from the mid-70s. Designed specifically for use with the DR-450 ignition distributor, this cap plays a vital role in delivering spark to the spark plugs in a sequential and efficient manner.
Constructed from high-quality materials, this distributor cap features a durable, black polymer body that effectively insulates the electrical components within while providing excellent resistance to wear and tear. The cap's surface is adorned with eight hexagonal-shaped ports, each housing a spark plug wire. These ports are strategically arranged to ensure proper spark delivery to each cylinder in the engine.

This distributor cap is a direct replacement for the original part and is designed to fit and function seamlessly with the OEM ignition system. It comes complete with a new set of seals to ensure a proper seal between the cap and the distributor housing, preventing any potential leakage of electrical charge.
