All BMC filters are sold with assembly instructions and all accessories needed to make assembly easy and fast.
The OTA lets the propulsor breathe thick, fresh air, rich in comburant oxygen, unlike a traditional air filter.

By mounting an air intake on a specifically favourable point of the car bonnet you can increase the speed of the air crossing the airbox considerably, with an advantage in the increase of fresh air capacity towards the engine.

ATTENTION: to be fitted only by professional technician.
