aFe Intake Tube - E36 M3 (for upgraded 3.5 inch HFM) (Retains ASC)

Our new intake boot for E36 M3 with S52 engine and 3.5" Euro HFM retains the stock ASC option while providing a full diameter tube to connect the HFM to the throttle body. Often the 3.5" HFM is used with the a reducer to fit onto the stock intake boot. This upgraded intake boot does not use the reducer which results in greater air flow to the throttle body.

This upgrade kit retains the ASC throttle body when upgrading to a 3.5" EURO MAF sensor. This coupling upgrade was designed to work with aFe�s P/N: 51-12392 / 54-12392, but it can also be used with other competitors intakes. The coupling is constructed of polyurethane for strength and durability. This engineered coupling upgrade increases air flow and velocity by controlling the air intake dynamics. This is a very simple bolt-on product and requires no cutting or drilling.

This item fits the following BMWs:
1996-1999 E36 BMW M3, M3 convertible
