BMC air filters are produced using a "Full Moulding" system that enables the characteristic red filter to be realized from a single mould with no welded joints thus avoiding easy breakage. The rubber used in BMC air filtering systems has a long life, is very durable and has optimum adhesion characteristics to all shapes of airboxes. BMC filters are made of a multi-layered cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity. All BMC air filters are pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kit. 1 Series (F20/F21) 114 d (HP: 95 | Year: 12 >) 1 Series (F20/F21) 114 i (HP: 102 | Year: 12 >) 1 Series (F20/F21) 116 d (HP: 116 | Year: 11 >) 1 Series (F20/F21) 116 i (HP: 136 | Year: 11 >) 1 Series (F20/F21) 118 d (HP: 143 | Year: 11 >) 1 Series (F20/F21) 118 i (HP: 170 | Year: 11 >) 1 Series (F20/F21) 120 d (HP: 163 | Year: 11 >) 1 Series (F20/F21) 120 d (HP: 184 | Year: 11 >) 1 Series (F20/F21) 125 d (HP: 211 | Year: 11 >) 1 Series (F20/F21) 125 d (HP: 218 | Year: 11 >) 1 Series (F20/F21) 125 i (HP: 218 | Year: 12 >) 2 Series (F22) 220 d (HP: 184 | Year: 14 >) 2 Series (F22) 220 i (HP: 184 | Year: 14 >) 2 Series (F22) 225 d (HP: 218 | Year: 14 >) 3 Series (F30/F31/F80) 320 d, Dx (HP: 184 | Year: 11 > ) 3 Series (F30/F31/F80) 320 i (HP: 184 | Year: 12 > ) 3 Series (F30/F31/F80) 320 i ED (HP: 170 | Year: 12 >) 3 Series (F30/F31/F80) 320 iX (HP: 184 | Year: 12 >) 3 Series (F30/F31/F80) 328 i (HP: 245 | Year: 11 > ) 3 Series (F30/F31/F80) 328 iX (HP: 245 | Year: 11 >) 3 Series GT (F34) 318 d Gran Tourismo (HP: 143 | Year: 13 >) 3 Series GT (F34) 320 i Gran Tourismo (HP: 184 | Year: 13 >) 3 Series GT (F34) 328 i Gran Tourismo (HP: 245 | Year: 13 >) 4 Series (F32/F33/F36/F82) 428 i (HP: 245 | Year: 13 >)
