Dinan Closed Cold Air Intake - 2016-2021 BMW M240i/340i/440i
Dinan has been developing performance parts for BMW vehicles for decades, and their closed cold air intake is a direct result of that engineering experience. Built around a carbon fibre airbox, this intake is designed to deliver measurable power gains while keeping intake temperatures low — something a standard open-filter setup simply can't match.
This listing covers the Dinan closed cold air intake for the 2016–2021 BMW M240i, 340i, and 440i, spanning the F22 / F23 / F30 / F32 / F33 / F34 / F36 chassis platforms. All share the same B58 engine fitment.
Key Features
- Carbon fibre closed airbox construction — isolates intake charge from engine bay heat
- Up to 15 hp gain at 6,000 RPM
- Up to 13 lb-ft torque gain at 6,000 RPM
- Direct fit replacement for the factory airbox
- Approximately 1 hour estimated installation time
- Dimensions: 610mm L x 457mm W x 254mm H (24 x 18 x 10 in)
- Weight: 3.6 kg (8 lb)
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please ensure your vehicle's year, trim level, and configuration are confirmed before ordering.
