Ferrari 412 Parts & Accessories

The Ferrari 412 was the final evolution of the 365 GT4 2+2 and 400 series grand touring lineage, produced from 1985 to 1989 with a 4.9-liter V12 and Bosch K-Jetronic fuel injection as standard equipment, making it one of the most powerful and refined of all Ferrari front-engine 2+2 grand touring cars. The 412 also introduced the option of an automatic transmission to the Ferrari lineup, with both a five-speed manual and a three-speed automatic available, a choice that influences the drivetrain parts landscape for these cars significantly. Owners maintaining a 412 work with an aging fuel injection system that requires specific K-Jetronic knowledge, a 4.9-liter V12 with its own maintenance requirements distinct from the 4.4-liter engines used in the 365 series, and Pininfarina bodywork that updated the 400's styling for the mid-1980s. The 412 remains a compelling grand touring value in the classic Ferrari market, and correct parts support keeps these cars on the road comfortably.

Popular Upgrades

Bosch K-Jetronic fuel injection components including fuel distributors, warm-up regulators, and injector rebuild kits are the most critical service items for the 412's aging injection system. Timing chain tensioners, valve cover gaskets, and water pump assemblies form the essential engine maintenance parts for the 4.9-liter V12. Suspension bushings, rebuilt Koni or Bilstein shock absorbers, and wheel bearings support chassis refreshes on this long-wheelbase grand touring platform. Brake hardware including master cylinder seals, caliper rebuild kits, and Ferodo friction materials maintain the braking performance appropriate for a 300-horsepower V12 grand touring car.

Performance and Handling

The 412's long wheelbase and 2+2 accommodation prioritize high-speed stability and smooth long-distance motoring over the sharper reflexes of Ferrari's two-seat sports cars, and the 4.9-liter V12's strong torque makes effortless progress at autostrada speeds the car's primary character strength. Refreshing the front and rear suspension geometry with new bushings and correctly specified dampers restores the confident, planted high-speed stability that made the 412 a preferred choice for owners covering long distances in comfort. The K-Jetronic injection system, when properly maintained with fresh fuel distributor components and correct fuel pressure, provides the smooth, consistent power delivery that distinguishes this system at its best from the uneven running that aging components produce. Correct wheel alignment on the large alloy wheels fitted to the 412 preserves both tire wear and the straight-line tracking precision that owners of this class of car expect.

What are the most common maintenance challenges on the Ferrari 412?

The Bosch K-Jetronic fuel injection system is the most common source of running quality issues on aging 412 cars, with worn fuel distributors, deteriorated warm-up regulators, and failing fuel accumulators producing lean running, hard hot-starts, and inconsistent idle that can be misdiagnosed as engine problems. The timing chain, unlike the rubber belt used on later Ferrari V8 models, requires periodic tensioner inspection and replacement rather than timed belt changes, and a stretched chain produces a characteristic rattling on cold start that worsens progressively if not addressed. Cooling system maintenance including thermostat, water pump, and hose inspection is also important on the 412, since the large displacement V12 generates significant heat that a compromised cooling circuit cannot manage effectively at sustained high speeds.

What is the difference between the Ferrari 412 manual and automatic transmission?

The manual 412 uses a five-speed gearbox that provides direct driver engagement and is generally preferred by enthusiasts for its feedback and the control it gives over engine speed. The automatic variant uses a GM Hydra-Matic three-speed unit that Ferrari specified to provide effortless long-distance driving for buyers who prioritized relaxed touring over sports car involvement. Transmission service parts, fluid specifications, and maintenance intervals differ significantly between the two gearbox options, and identifying which transmission your car has before sourcing drivetrain service parts prevents ordering incorrect hardware.
