BMW Z4 E85 E86 3.0i N52 Cold Air Intake aFe Magnum FORCE Stage 2 Pro 5R 54-11942

For E85 and E86 Z4s with the N52 engine (2006-2008), this aFe Magnum FORCE Stage 2 intake isn’t a ‘daily driver plus’ compromise - it’s a fast road or track day air system that actually moves more air, without triggering CELs or demanding a remap.

• Stage 2 spec: Pro 5R cotton gauze filter, one-piece heat shield, smooth-moulded intake tube and 3-angle adaptor - built for flow, not just looks
• Fits N52 only: Not for N54/N55 Z4s, not for 2.5i, not for post-2008 models - no ambiguity on E85/E86 3.0i compatibility
• Decat-adjacent gains: +18 bhp and +15 lb-ft torque on dyno - real numbers, measured at the wheels, no ‘up to’ padding
• Washable, reusable filter: No disposable paper filters here - clean and re-oil the Pro 5R as part of your regular service routine
