One of the easiest ways to gain horsepower and improve your throttle response on the BMW 40i B58, turbocharged engine, is with an air intake kit. Agency Power’s new short ram air intake kit for the M240i, 340i, and 440i is a great first modification to do. The intake kit is a complete replacement for the OEM air box. The kit includes a new aluminum intake tube with CNC machined MAP sensor mount, precision cut heat shield with mounting tabs, and a new high flow air filter. The MAP sensor mount has been CNC machined out of 6061 aluminum to retain the factory fitment for proper readings.? It is than TIG welded to the aluminum intake tube for proper placement. The main part of the intake is the high flow air filter. It features an inlet on the end cap to allow for an even larger volume of air to come through than a standard cone filter. The design improves air filtration while increasing air flow. The air filter is finished off with the Agency Power text and AP logo on the rubber end cap. The heat shield is water jetted from aluminum with rubber trim to provide a secure fit and seal when the hood closes. It is designed to prevent direct hot air from the engine being sucked into the filter. Each heat shield features the AP logo neatly cut out from the shield panel for added style. All parts are finished in a matte black powder coat for an OEM look while the cylindrical air filter features a blue element matching to the BMW Roundel logo. With the new air filter, your turbocharger can breathe better than the factory intake allows. This is noticeable as you step on the accelerator and hear the turbo work (sucking air noise). Release the throttle and the factory blow off valve noise (whoosh) is more audible and keeps you entertained through the gears!
