SLE Intake System – G20 M340i, G22 M440i & G42 M240i (B58)
SLE is proud to offer a complete intake solution for the BMW B58-powered G20 M340i, G22 M440i, and G42 M240i. Our full intake system is designed to deliver maximum performance, aggressive sound, and perfect fitment—all at an unbeatable value.
This isn’t just a filter and pipe—it includes a full upgraded turbo inlet, eliminating the restrictive factory piece and ensuring smooth, unrestricted airflow directly into the turbo.
At the heart of the system is a massive high-flow inverted cone filter paired with a 4″ aluminum intake pipe and silicone couplers for maximum durability and performance. The CNC-machined MAF flange ensures accurate sensor readings and factory-like drivability.
Expect a deeper intake sound, quicker spool, and gains of up to 15–20HP on tuned setups.
