BMW N54 Dual Cone Intake Filters DCIMMP Dual cone intake filters. High quality cotton intake filters. Goes great with MMP silicone inlets if you dont already have DCI filters. Also the blue color looks way better under your hood than the dark red color filters. Can be washed, cleaned and re oiled for long term continued use. Why pay more for the same performance? Go with MMP DCI intakes, save money, and burn rubber! :) these work with any model series car with an N54 engine LHD or RHD
