Frequently asked questions

What is the ESR3173 air duct and what does it do?
The ESR3173 is the upper right-hand air intake duct on the Land Rover Defender. It channels air from the right-hand front wing inlet toward the engine air cleaner system. It's a genuine Land Rover part fitted to TDi and Td5 Defenders up to 2006.
Does the ESR3173 work with another duct?
Yes. The ESR3173 upper duct pairs with the lower duct ESR3175 to form the complete wing-to-air-cleaner inlet path. If you're renewing a perished intake, you'll typically want both sections to restore the full duct run.
Why would an air intake duct need replacing on a Defender?
Air intake ducts typically need replacing when the plastic cracks or the joints perish with age and engine bay heat. A split duct can draw in unfiltered air. Renewing it restores a sealed path from the wing inlet to the air cleaner.
Which Defenders does the ESR3173 fit?
The ESR3173 fits the Land Rover Defender up to 2006 with TDi and Td5 engines. It's the right-hand upper section. Check your VIN and existing duct layout to confirm the correct upper part before ordering.
