Dinan Cold Air Intake - BMW M340i/M440i (G20/G22/G23/G26), M240i (G42)

Dinan's intake for the G-chassis B58 cars replaces the factory airbox with a bigger, semi-open setup. Dinan says it is at least 58% less restrictive than stock and rates it at up to 9 wheel horsepower and 8 lb-ft on an otherwise stock car. The secondary inlet also lets more turbo spool and blow-off sound into the cabin.

What you get

• Airbox about 60% larger than the factory one.
• More filter area, up from 82 to 115 square inches.
• Semi-open design with a secondary inlet, which makes the intake more audible.
• Dinan warranty for the rest of the car's factory limited warranty (up to 4 years or 50,000 miles) or 2 years with unlimited miles, whichever is longer.
