Ferrari Testarossa Parts & Accessories

The Ferrari Testarossa defined a generation of supercar design when it debuted at the 1984 Paris Motor Show, with its bold side strakes, wide rear bodywork, and flat-12 engine mounted longitudinally behind the driver in a mid-engine layout that challenged every contemporary rival on sheer visual impact. Powered by the 4.9-liter Tipo F113 horizontally opposed twelve-cylinder engine producing 390 horsepower through a four-cam, forty-eight valve design with Bosch K-Jetronic fuel injection, the Testarossa remains one of the most visually and mechanically compelling cars Ferrari ever produced. The name translates to red head in Italian, referencing the distinctive red-painted cam covers visible through the engine's transparent cover. This collection supports Testarossa owners with parts verified to the specific Tipo F113 flat-12 architecture and wide-body chassis.

Popular Upgrades

Bosch K-Jetronic fuel injection service components including the fuel distributor, warm-up regulator, and fuel accumulator are the most frequently needed maintenance items given the age of virtually every surviving Testarossa and the sensitivity of the continuous injection system to pressure drift. Timing belt replacement kits for the flat-12 engine require the complete set of twelve individual cam drive belts plus their tensioners, a significant service undertaking that specialists recommend combining with water pump replacement and cooling hose renewal. Stainless steel exhaust systems from Tubi Style and other Italian specialists deliver an authoritative flat-12 soundtrack and reduce backpressure on the aging factory steel system, and Koni or Bilstein period-specification shock absorbers restore the suspension compliance lost to decades of damper fatigue.

Performance and Handling

The Testarossa's wide rear track, necessitated by the flat-12 engine's width, gives the car a distinctive handling balance with excellent rear grip but a wide physical footprint that requires careful attention to wheel bearing and rear hub specifications during service. The rear-mounted transaxle uses a five-speed manual gearbox with a final drive unit integral to the casing, making gear oil selection critical for protecting both the transmission internals and the ring-and-pinion gear set that handles the full engine torque output. Front suspension uses double wishbones with coil springs and Koni shock absorbers, and sourcing replacement front springs to original rate specifications is important for maintaining the factory chassis balance that makes the Testarossa's handling so distinctive.

What are the most critical maintenance items on the Ferrari Testarossa?

The flat-12 engine uses twelve individual cam drive belts, two per cam on a six-belt per bank system, and Ferrari's original 15,000-kilometer replacement interval is widely shortened to annual replacement by specialists given the catastrophic consequences of a belt failure on this interference engine. The K-Jetronic injection system requires a full pressure test of the fuel distributor, cold start circuit, and warm-up regulator at every major service to verify correct injection quantity across all twelve cylinders. Cooling system integrity is particularly important on the Testarossa given the flat-12's width and the routing complexity of the coolant passages, and a full cooling system pressure test and thermostat replacement should accompany every timing belt service on this engine.

How do the Testarossa, 512 TR, and 512 M differ for parts?

The Testarossa produced from 1984 to 1991 uses the original Tipo F113 A engine with K-Jetronic injection and a single rear mirror, while the 512 TR introduced for 1992 features the upgraded Tipo F113 B engine with revised porting, Motronic injection, and dual side mirrors for improved visibility. The 512 M produced from 1994 to 1996 further refined the engine to Tipo F113 C specification with additional power and revised exterior styling including circular headlights replacing the original pop-up units. Mechanical components including cam belts, pistons, and fuel injection parts carry different part numbers across these three generations despite the shared flat-12 architecture.

Why These Parts Fit Right

Parts in this collection are cataloged to Ferrari Testarossa production years from 1984 to 1991, clearly distinguished from 512 TR and 512 M components that use different engine and injection specifications. Compatibility notes cover K-Jetronic versus early Motronic variants, single versus dual mirror body configurations, and early versus late production fascia differences. Fast shipping from stocked inventory keeps your Testarossa restoration or maintenance project on schedule.
