Description

Engine overview

VK45DE is Infiniti’s 4.5-liter DOHC V8 from the Q45 and FX45. This listing is a Q45 RWD engine with source reference 099572. FX45 AWD accessory and pan differences are real. It is not a VK56 truck V8 and not a VQ35 with extra cylinders imagined.

Typical applications

Listed application window: 2002–2006 Infiniti Q45. Year/make/model get you onto the right aisle. VIN, oil pan, and engine code decide whether the assembly actually ships.

Engine configuration

4.5L DOHC V8, Naturally aspirated, DOHC, 4 valves per cylinder, Aluminum block, Aluminum head. Listed dress: complete engine. No transmission is included unless named on this page. Published family output: 340 hp class in Q45 / FX45 applications. That is not a dynamometer result for this serial.

What buyers should verify

Stamped engine code, oil pan shape, engine mounts, exhaust manifolds or turbo/blower hardware, and whether the harness and ECU in the vehicle match this generation. Send this SKU with the VIN on an engine enquiry before freight is scheduled.

Included assembly information

Complete-engine dress means block, heads, and the intake/front accessories visible in the photographs. Turbochargers, blowers, ECUs, flywheels, and exhaust manifolds are included only when shown or named.

Installation considerations

JDM engines often differ in harness connectors, emissions equipment, and mount geometry from the US-market equivalent. Budget for sensors, manifolds, and an ECU strategy that the vehicle actually has. Compression or leak-down data is supplied only if it is written on the order—do not assume a test sheet exists because the engine is imported.

Shipping considerations

The engine ships on a pallet as freight after the delivery ZIP, residential versus shop, and liftgate needs are confirmed. Cost and transit depend on destination. Tracking is issued when the carrier has the pallet.

Warranty information

Used JDM coverage is stated per engine at the time of sale. No blanket term, labor reimbursement, or return window is implied by this listing. Read the note on the order before freight is scheduled.
