aFe POWER Momentum GT Pro 5R Cold Air Intake for Select 2016-2026 BMW 540i/740i/840i (L6-3.0L) 50-70073R

Fits select 2016-2026 BMW 540i, 740i, 840i, X3 M40i, and X4 M40i (L6-3.0L) models. This system replaces the restrictive factory air box with a high-flow, heat-resistant setup designed for street and track performance.

The Momentum GT system features a smooth, one-piece sealed housing made from cross-linked polyethylene (XLPE) to resist heat soak. At its core is a 6-inch tall, 360-degree radial flow air filter using Pro 5R media—five layers of progressively finer oiled cotton gauze. This design is measured at 255 CFM @ 7" H2O, outflowing the factory intake by 24%. A large, clear sight window allows for quick filter inspections without disassembly, while the computer-designed intake tube ensures maximum power gains and a precise fit.
