aFe Momentum GT Pro Dry S Intake System - 2017-21 BMW 540i G30 B58

aFe's Momentum GT replaces the factory B58 intake in the 540i with a sealed one-piece housing and a larger round filter. This version uses the oil-free Pro Dry S filter, so cleaning is a wash and dry. aFe measured 245 CFM, about 20% more than the stock intake, with dyno gains of up to 9 hp and 16 lb-ft of torque.

What you get

• Sealed one-piece housing made from heat-resistant XLPE cross-linked polyethylene.
• Clear sight window for checking the filter without disassembly.
• Pro Dry S filter, a 6 in tall, 360-degree radial element with three layers of synthetic media and no oil required.
• XLPE intake tube designed to resist heat soak.
• Factory mounting points, with aFe's filter-to-housing interface using about half the parts of a typical intake.

Good to know

• Not CARB exempt, so aFe does not sell it for California-registered vehicles.
• Designed to fit cars with the factory strut brace without modification.
