The do88 intake resonator delete replaces the two factory rubber hoses that run between the air filter box and throttle body on BMW N51, N52 and N53 inline-six engines, removing the bulky intake resonator that muffles induction sound. The two-piece silicone set is built from three to five layers with an integrated steel-wire helix, opening up airflow and intake tone while resisting the age cracking of the OE rubber hoses. It fits both single-stage and three-stage intake manifolds. This is the blue finish.
