About Hitachi Auto Products

Few names in global manufacturing carry the weight of Hitachi. Founded in 1910 in Tokyo, Japan, the company built its reputation on a simple but powerful mission: contribute to society through superior, original technology. Over more than a century, that commitment has driven Hitachi into nearly every corner of modern industry — and the automotive world is no exception. Hitachi Auto Products brings that same engineering DNA to the parts under your hood and beneath your vehicle.

Hitachi's presence in the automotive industry dates back to 1930, when the company began producing automotive electrical components. Decades of OE (original equipment) manufacturing experience mean that Hitachi parts are engineered to the same tolerances and performance standards as the components that came off the assembly line with your vehicle. That heritage is especially evident in the brand's engine management lineup, where precision matters most.

Engine Management Expertise

At the heart of Hitachi's aftermarket catalog is a deep bench of engine management components. The brand is a recognized leader in mass air flow sensors — the critical devices that measure the volume and density of air entering the engine so the ECU can calculate the correct fuel delivery. Hitachi pioneered hot-wire airflow sensor technology and continues to manufacture MAF sensors built to exacting OE specifications, helping restore proper fuel trim and throttle response on a wide range of domestic and import vehicles.

Equally important to smooth combustion is a strong, consistent spark. Hitachi's ignition coils are designed to sit close to the spark plug for maximum efficiency, transforming battery voltage into the tens of thousands of volts needed to fire the air-fuel mixture reliably. Each coil is manufactured from premium-grade materials and tested for durability and consistent output — ensuring optimal engine efficiency and better fuel economy over the long haul.

Steering & Suspension Systems

Hitachi's engineering reach extends well beyond the engine bay. The brand produces complete rack and pinion assemblies built with high-accuracy rack gears, ball screws, and pinion components — many manufactured in-house — to deliver precise, confidence-inspiring steering feel. For vehicles with hydraulic steering, Hitachi's power steering pumps feature cast aluminum housings for reduced weight and high thermal efficiency, with precision-machined internal surfaces that minimize pressure loss and operating noise.

For luxury and air-ride-equipped vehicles, Hitachi also supplies air suspension compressors engineered to restore the ride height and handling characteristics those systems are designed to deliver. These compressors reflect the same OE-supplier standards Hitachi applies across its entire product range — 100% new construction, never remanufactured.
