Land Rover Defender V8 – L663-Ramair Replacement Air Filter Upgrade

Short Description

This Ramair Replacement Air Filter Upgrade is engineered exclusively for the Land Rover Defender L663 V8 P525 supercharged engine. It is a direct OEM drop-in replacement for restrictive factory paper filters. It delivers improved airflow, sharper throttle response and reusable performance filtration while maintaining full factory ECU and diagnostics compatibility.

Product Technical Overview

V8-Specific Ramair Technical Design

Tailored for the 5.0L supercharged V8 platform, this Ramair filter set features performance-focused engineering. First, dual-layer 15mm foam media increases volumetric airflow to the supercharger. Second, reinforced stainless steel cage support prevents filter flex under high suction pressure. Third, progressive foam density balances maximum airflow and precise particulate filtration. As a result, the engine achieves consistent airflow efficiency across the full RPM range without compromising engine protection.

Key Technical & Performance Benefits

True OEM Drop-In V8 Fitment: Exact factory sizing for L663 P525 airbox housing. No drilling, trimming or permanent modifications required.
Supercharged Airflow Improvement: High-flow foam media reduces factory intake restriction. It enhances supercharger efficiency and linear throttle response.
Dual-Layer Foam Filtration: Progressive density foam traps fine road dust and debris. It protects supercharger internals and engine components.
Reusable & Serviceable Design: Fully washable and re-oilable construction eliminates disposable paper filter replacements. It reduces long-term service costs.
Full JLR Diagnostic Compliance: Maintains factory MAF sensor readings and intake pressure parameters. It prevents ECU fault codes and warning lights.
Enhanced V8 Intake Acoustics: Optimised airflow unlocks subtle natural supercharger induction tone. It improves driving feedback without excessive cabin drone.

Vehicle Compatibility

This Ramair Air Filter Upgrade is designed exclusively for 2021+ Land Rover Defender L663 V8 P525 5.0L supercharged petrol models. It fits all Defender 110 V8 variants. It is not compatible with standard 2.0L/3.0L Ingenium petrol/diesel engines, Defender 90 L663 or pre-2020 Defender chassis.

Kit Inclusions & Transactional Details

Each order includes a complete twin set of genuine Ramair performance foam replacement filters tailored for the L663 V8 airbox. Every filter undergoes pre-dispatch quality testing for dimensional accuracy, foam density consistency and structural integrity. Simple plug-and-play installation supports routine service integration. This JLR-approved performance upgrade optimises V8 engine airflow, responsiveness and long-term reliability while retaining full factory vehicle warranty compliance.
