Скачать или смотреть N54: Stock Airbox VS BMS DCI underhood camera

In this video, I've got a GoPro Session mounted in the engine compartment with an LED light source. You can hear the different sounds of the stock airbox, airbox with diverter valves vented, and with the Burger Motorsports Dual Cone Intake. The air filter with the airbox is the AFE drop in panel filter.

The test car is a 2007 BMW 335i coupe. The current mods are Cobb Tune S2+ aggressive, Mishimoto Intercooler, VRSF Downpipes, stock exhaust after the downpipes, NGK spark plugs (ILZKBR7B8DG) gapped to 0.032". Full tank of 92 octane with 16 oz Torco Accelerator.

It makes slightly louder spooling sound from inside the car. Look at how the stock charge pipe swells under boost!

Thanks for watching!
