Review on 🚀 Advanced aFe Power Magnum FORCE 54-10691 BMW X5 (E53) Performance Intake System - Unleash Your Vehicle's Potential by Jason Rogness

Very good tuning. It was very easy to install, well made heat shield. Noticeable gain, but not as big as I was hoping, but letting the X5 breathe better is a good thing. It's also CARB-approved, which is important in California. *UPDATE - 11/20 After replacing some parts and resetting, the code returned. After removing the CAI and resetting the code it never came back. I've had CAI on several vehicles and this one looks very good but has minimal impact on performance. I am really very disappointed and wish it would work.
