BMW M140i / M240i F2x and 340i / 440i F3x B58 Alpha Competition Intake Kit

Featuring with a large volume black multi-layer silicone intake hose, an aluminum MAF housing and a high-performance air filter, this Alpha Competition air intake system fits without any modifications on the B58 engines of the BMW M140i / M240i F2x and 340i / 440i F3x. Retaining the lower part of the OEM airbox (particularly efficient) and replacing the upper part (less efficient), this intake will offer an aggressive tone under load and a gain of over 11hp on a stock engine (22hp on stage 2 tuned engine).
