Please note : this product does not fit the E series of BMW N55.
For this application we have opted for large cross sectional turbo inlet tube with integrated MAF and a smooth non concentric expanding inlet tube which with silicone couplers. The expanding large volume inlet tube acts like a large velocity stack which accelerates the airflow and is much larger than the small and short velocity stack fitted to the internals of the oem intake. The result of the smoother airflow from our inlet tube is a far smoother lower rpm torque availability from the engine vastly improving drivability. Throttle response is immediately felt to be smoother and more eager. The inlet tube is attached via a stainless steel v band clamp to the air filter housing which attaches directly to the oem front air feed and has a frontal opening facing towards the headlight.
The factory intake system of the BMW M2 N55 system is not a sealed design. The front opening attaches directly the front inlet which is in turn attached to the front air ducts located behind the grills and there is a second opening which opens into the engine bay towards the headlight. This clearly suggests that one opening is not enough and the engineers had to create a separate opening to meet the high airflow demands of the engine which is understandable since the front intake has barely the same cross sectional area as the MAF. The design is still however efficient as far as keeping the intake air temperatures low. As far as being an ultimate performance intake, it is most certainly not with it’s angular design, small volume and having an airflow with a directional path which is not direct.
