About Forecast Auto Parts

Forecast is a trusted name in the automotive aftermarket, specializing in ignition system components and engine management sensors that keep older and classic vehicles running reliably. With a catalog spanning everything from distributor caps and ignition switches to idle air control valves and temperature sensors, Forecast has built a reputation as a go-to source for OE-style replacement parts that fit right and function correctly.

Forecast parts are widely carried by major automotive retailers and are a popular choice among DIY mechanics and professional technicians alike — particularly for domestic vehicles and trucks from the 1980s through the early 2000s, where distributor-based ignition systems and throttle-body fuel injection remain common. The brand focuses on delivering dependable, vehicle-specific fitment so owners can restore proper engine operation without the guesswork.

Ignition System Expertise

At the heart of the Forecast lineup is a strong selection of ignition components. The brand's distributor caps are engineered to protect internal distributor components and maintain reliable high-voltage transfer from the ignition coil to the spark plugs — a critical function on any vehicle that still relies on a distributor-based ignition setup. Alongside these, Forecast offers ignition switches designed to precise OE tolerances, ensuring consistent electrical contact and reliable engine starting across a wide range of vehicle applications.

Engine Management & Sensor Components

Modern and legacy fuel-injected engines depend on a network of sensors and actuators to maintain smooth, efficient operation. Forecast addresses this need with a solid offering of engine management parts. Their idle air control valves help regulate airflow at idle, preventing the rough idling, stalling, and hard-starting symptoms that a failing IAC valve can cause. For temperature monitoring, Forecast produces both engine coolant temperature sensors and HVAC temperature sensors, giving the engine control unit and climate control system accurate readings to manage fuel delivery and cabin comfort effectively.
