Ramair Performance Air Intake Kit – BMW F-Series N57 3.0 Diesel (Euro 5) with Pleated Cotton Filter
This Ramair intake kit (PRK-336-BK) is a direct upgrade over the standard factory air intake on the BMW F-Series with the N57 3.0 diesel engine. It replaces the restrictive standard airbox with a freer-flowing setup, helping your engine breathe more efficiently – which in turn can improve throttle response and overall performance.
The kit centres around Ramair’s pleated cotton performance filter. Unlike a standard paper filter, a pleated cotton filter allows more air to pass through whilst still filtering effectively. More air reaching the engine means the turbocharger (the device that forces air into the engine to produce more power) can work more efficiently, and you may also notice a more pronounced induction sound when accelerating.
What’s Included
- Ramair pleated cotton performance air filter
- Black powder-coated CNC-cut heat shield – helps keep hot engine bay air away from the intake
- Roto-moulded intake pipe for smooth, unrestricted airflow
- Full fitting hardware and step-by-step instructions
What to Expect
The improvements from an intake kit are real, but it’s worth setting honest expectations. You’ll likely notice a sharper, more responsive feel when you put your foot down, along with a deeper, more audible induction note from the turbo under load. Outright power gains from an intake alone are modest – the biggest benefits come when paired with other supporting modifications such as an ECU remap (a software adjustment to the engine’s management system).
The heat shield is an important part of this kit. It helps isolate the filter from warm air radiating off the engine, encouraging cooler, denser air into the intake – cooler air carries more oxygen, which is better for combustion and performance.
Installation is designed to be straightforward and is achievable at home with basic tools, thanks to the included step-by-step instructions. No specialist equipment is required.
Fitment note: This kit is designed for BMW F-Series models fitted with the N57 3.0 litre diesel engine (Euro 5 emissions standard). Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific model and year before purchasing.
