OVERVIEW
Designed for the B48-powered G01 X3 and G02 X4 30i, this BMS billet intake trades the factory MAF housing and airbox top for a black anodized billet aluminum housing carrying a large inverted cone filter. The stock cold air duct, insulated base and heat shield all remain, so intake temperatures stay in check.
The higher-flowing setup improves throttle response, helps the turbo spool and adds a sportier sound under acceleration. Choose blue or red oiled filters or a dry filter; the kit is plug-and-play and can be returned to stock whenever needed.
