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.

Product Development:

Our E70 35d Intake was designed, engineered, tested, and quality-inspected by our Research and Development team at our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modelling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

In BMWs with the N55, the intake system is partially limited. The bottom portion is lightweight and great for feeding cold air to the intake, but the top portion is excessively restrictive. Working with some of the original equipment, this intake continues to utilize the bottom portion of OE ducting and heat shielding, but replaces the top with new high flow ducting and a performance filter. Extensive testing showed up to a 10+ HP gain to the wheels and allows for quicker turbo spool speed. Plus, this design gives you a great sound improvement, letting you hear both the intake and turbo spooling!

Installation and removal is extremely quick and easy, taking only 5 minutes in the driveway!
