LANDNOVO — Precision in Motion. Engineered by GB.

Is your Land Rover experiencing poor acceleration, rough idling, or an illuminated check engine light? The culprit is often a failing throttle body. The LANDNOVO LR078546 Throttle Body Assembly is a premium, direct OE-grade replacement engineered to restore your vehicle's engine performance and drivability.

The LANDNOVO Difference

LANDNOVO is a premium automotive brand with a distinct British engineering heritage, crafted for discerning drivers who demand nothing but the best for their vehicles. Every LANDNOVO component is Designed by GB — a mark of British precision, quality, and durability.

This throttle body assembly is manufactured to the highest standards, matching the quality of the original equipment (OE LR078546) that came factory-installed on your Land Rover. It is a complete drop-in replacement, designed for a straightforward installation.

Why Choose the LANDNOVO Throttle Body?

The throttle body is a critical component of your vehicle's air intake system. It houses a butterfly valve that controls the amount of air entering the engine, regulating engine speed and power output in response to the driver's accelerator pedal input. A faulty throttle body can lead to hesitation, rough idle, stalling, and reduced fuel efficiency.

This LANDNOVO throttle body is specifically engineered for Land Rover 3.0L V6 diesel engines. It comes as a complete assembly including the electric motor, ensuring a seamless plug-and-play installation. Instead of paying dealership prices, the LANDNOVO throttle body provides the same OE-level reliability at a fraction of the cost.
