Ferrari 599 Gtb Fuel Injectors

Ferrari 599 Gtb Fuel injectors

Starting at $55.95, AutoBuffy stocks 1 fuel injectors from Bosch to fit the Ferrari 599 Gtb. A fuel injector delivers a precisely metered spray of fuel directly into the engine's intake port or combustion chamber. When one clogs or fails, the engine loses that cylinder's fuel contribution, causing rough running, poor economy, and potential catalytic converter damage.

Signs your Ferrari 599 Gtb needs new fuel injectors

  • Rough or uneven idle that worsens when the engine is cold — a stuck-open or clogged injector upsets the air-fuel mixture at low RPM
  • Misfires under acceleration logged as cylinder-specific codes (e.g., P0301–P030x) pointing to an injector not delivering fuel on demand
  • Noticeable drop in fuel economy over a short period with no other obvious cause
  • Strong smell of raw gasoline from the exhaust or engine bay, indicating a leaking injector passing excess fuel
  • Hard starting or extended cranking, especially after the vehicle has sat overnight, caused by a leaking injector that bleeds down fuel rail pressure
  • Black, sooty exhaust or fouled spark plugs on one or more cylinders from a stuck-open injector flooding that cylinder with fuel

Which fuel injector should you buy for your Ferrari 599 Gtb?

The most important decision is matching the injector's flow rate and connector style exactly to the Ferrari 599 Gtb's original specification — an incorrect flow rate will shift the air-fuel ratio and trigger check-engine codes even if the injector physically fits. Beyond OE-spec replacement, you can choose between remanufactured units, OEM-equivalent new injectors, or upgraded high-flow units if the engine has been modified.

Remanufactured OE-spec injector
Best for
Budget-conscious owners who want a proven flow rate at lower cost
What you get
Cleaned, ultrasonically tested, and rebuilt core with new o-rings and filters; matched to factory flow rate
New OEM-equivalent injector
Best for
Owners who want new internals without dealership pricing
What you get
Brand-new solenoid and nozzle, OE flow rate and spray pattern, direct plug-and-play fitment for the Ferrari 599 Gtb
OEM / dealer-sourced injector
Best for
Owners under warranty or who want the exact original part
What you get
Manufacturer-spec quality, guaranteed fitment, typically the highest per-unit price
High-flow performance injector
Best for
Modified engines with increased horsepower that need more fuel delivery
What you get
Higher lb/hr flow rate requiring ECU tuning; not appropriate for a stock Ferrari 599 Gtb without reprogramming

Replacing fuel injectors on a Ferrari 599 Gtb

Moderate⏱ 1–3 hoursFuel line disconnect tool setTrim or clip removal tool (for intake components)Standard and metric socket setFuel pressure gauge (to verify rail is depressurized)Clean rags and nitrile gloves for fuel handling

Before removing any components, relieve fuel system pressure by locating the fuel pump fuse or relay, running the engine until it stalls, and confirming zero pressure with a gauge. Disconnect the battery, remove the fuel rail mounting fasteners, and carefully pull the rail with injectors attached before swapping each injector with new o-rings lightly lubricated with clean engine oil. Reinstall in reverse order, restore the fuel pump fuse, cycle the ignition several times to repressurize the rail, and check for leaks before starting the engine.

Frequently asked questions

How much does it cost to replace fuel injectors on a Ferrari 599 Gtb?
Parts start at $55.95 per injector on AutoBuffy. Most owners replacing a single injector spend less than replacing the full set, but sets are often discounted. Add shop labor of one to three hours per injector depending on engine layout, or do it yourself using basic hand tools to save significantly.
Can I drive my Ferrari 599 Gtb with a bad fuel injector?
Short trips are possible, but continued driving risks catalytic converter damage from unburned fuel, fouled spark plugs, and accelerated wear on the cylinder running lean or rich. A misfiring cylinder also stresses the engine's internals over time. Replace a faulty injector as soon as symptoms appear to avoid compounding repair costs.
Should I replace all fuel injectors at once on my Ferrari 599 Gtb?
If one injector has failed from age or clogging rather than physical damage, the others likely have similar mileage and wear. Replacing the full set at once saves repeated labor costs and ensures balanced fuel delivery across all cylinders. If only one injector failed due to a manufacturing defect at low mileage, a single replacement is reasonable.
Will cleaning fix my Ferrari 599 Gtb's fuel injectors, or do I need to replace them?
Cleaning works for partially clogged injectors showing reduced flow — professional ultrasonic bench cleaning can restore up to 90 percent of flow in mildly restricted units. It will not fix injectors with a failed solenoid, cracked body, worn pintle, or internal corrosion. If the Ferrari 599 Gtb is misfiring with a cylinder-specific code, cleaning alone rarely resolves it.
How do I know if my Ferrari 599 Gtb has port or direct fuel injectors?
Port injectors spray into the intake manifold just upstream of the intake valve and are generally accessible from the top or side of the engine. Direct injectors spray into the combustion chamber at very high pressure and are mounted in the cylinder head. Check your Ferrari 599 Gtb's owner's manual or the underhood emissions sticker — or look up the 599 Gtb engine code — to confirm the injection system type before ordering.
What causes fuel injectors to fail on a Ferrari 599 Gtb?
The most common causes are carbon and varnish buildup from low-quality fuel or extended oil change intervals, internal o-ring or seal degradation from heat cycling, and corrosion from ethanol-blended fuels sitting in the rail. Electrical solenoid failure from voltage spikes or wiring issues is less common but renders the injector completely non-functional regardless of the nozzle condition.
