aFe Momentum GT Pro 5R Induction Upgrade for B58-powered F-Series BMWs – PN 54-76309

Transform the way your B58 straight-six breathes with this premium sealed induction system from aFe. The Momentum GT Pro 5R delivers a colder, denser charge to your turbocharged 3.0 engine for real-world gains you can feel on the road and see on the dyno. Expect sharper pedal response, stronger mid-range pull and a deeper, more purposeful intake note under load, all while retaining a clean OEM-style appearance under the bonnet.

We run this exact kit on our own shop cars at MJ Modifications and have installed it for many customers. Feedback is consistently positive: better drivability, quicker spool, a satisfying whoosh under acceleration and tidy fit-and-finish that looks factory. It is one of the most effective plug-in breathing upgrades for stock and tuned B58 applications.
