BMW Performance Intake Kits for BMW X Series E70 (2007-2013)

This isn't just another generic "filter on a stick" or a brittle, 3D-printed prototype. This cold air intake was engineered from the ground up by true 35d enthusiasts who understand exactly what the BMW M57 engine needs. Designed specifically for the diesel X5, it delivers unmatched size, build quality, and real-world effectiveness.

By ditching the restrictive factory airbox, this system completely transforms your engine bay. It utilizes a massive, custom-fabricated aluminum shovel to scoop up dense, cold air and ram it directly into the largest high-flow cone filter that can physically fit under the hood. If you want to slash intake air temperatures (IATs), maximize your diesel's performance, and install the most comprehensive intake system on the market for your X5, Turner Motorsport has you covered.

Built from heavy-duty 12-gauge and 6061-T6 aluminum and wire-reinforced silicone, this durable setup is built to handle high diesel boost levels without breaking a sweat. Best of all, it backs up its rugged looks with a massive 38% increase in airflow over stock, ensuring your M57 engine gets all the air it needs to perform at its peak.
