Air Intake Kit for Land Rover Discovery (2014-2020) V6 Supercharged 3.0L

High-Flow Dual Air Intake Kit for 2014-2020 Land Rover Discovery

What it does: This dual performance direct air intake kit replaces the restrictive factory air boxes on the AJ126 3.0L Supercharged V6 to lower intake air temperatures, increase volumetric efficiency, and deliver a verified 9-11 wheel horsepower gain.

The Stock Discovery Air Flow Limitations

The OEM dual air box setup on the L319 and L462 Land Rover Discovery chassis is engineered primarily for sound suppression and deep water fording, resulting in a heavily baffled, highly restrictive intake tract. These plastic factory enclosures are prone to heat soak within the engine bay, especially under sustained load or off-road conditions where airflow is minimal. The corrugated intake tubing creates unwanted turbulence, disrupting laminar flow to the throttle body and effectively starving the supercharger of cold, dense air. This restriction becomes increasingly apparent in the upper RPM range, where the AJ126 supercharger struggles against internal vacuum, limiting throttle response and overall engine volumetric efficiency.

The Engineering Solution

By eliminating the factory baffles, this direct air intake upgrade straightens the airflow path to the forced induction system. The kit utilizes high-flow filters and dedicated metal heat shields to block radiant heat from the engine block. This maintains lower Intake Air Temperatures (IATs) while optimizing airflow velocity. Heavy-duty clamps ensure a vacuum-tight seal under boost, preventing unmetered air leaks. The streamlined design reduces supercharger parasitic loss, yielding a measurable 9-11 hp increase at the wheels. Installation is a straightforward 30-minute bolt-on process requiring no permanent modifications.

Technical Specifications
