Description
Fitment & Application
The ITG WB-430 is a direct drop-in performance upgrade for the flat panel filter used in standard factory airboxes. It ensures a precision, airtight seal within the original housing, protecting your engine from harsh off-road contaminants while maximising available airflow.
Vehicle Compatibility
- Land Rover Defender: TD5 models (1998–2006)
- Land Rover Discovery 2: TD5 & V8 models (1998–2004)
- Direct high-performance replacement for factory Land Rover part number LR027408 and ESR4238 .
Why Choose the ITG WB-430 Profilter?
Standard paper elements quickly clog, restricting airflow and dragging down engine efficiency—especially in dusty off-road environments or during demanding towing cycles. ITG filters utilise a unique multi-layered reticulated foam design that traps dust particles throughout the entire thickness of the element rather than just on the surface. This allows the filter to sustain optimum airflow levels for longer, noticeably improving throttle response and combustion efficiency.
Unlike standard paper filters that must be discarded at every service interval, the ITG WB-430 is fully washable and reusable, making it a highly cost-effective and environmentally sound upgrade for your Defender or Discovery 2.

ITG Air Filters
British-made ITG performance air filters for Land Rover vehicles
ITG air filters are made by Induction Technology Group, a British performance filtration specialist with more than 30 years’ experience in automotive, motorsport and specialist vehicle air filter development. ITG filters are used in road, performance and competition applications where airflow, filtration and build quality matter. ITG filters are a strong choice where you want a reusable foam air filter for a Land Rover standard airbox or a specific cone-filter intake setup. Direct replacement panel filters are usually the easiest upgrade, fitting in place of the standard paper filter while retaining the original airbox. Cone filters are more application-specific and should be chosen to suit the intake arrangement being used.
