Universal Interface Motorcycle Air and Oil Filters, 12mm Car Cold Air Intake Filter, Turbo Crankcase Breather Vent (Black)

Specification:
Applicable Models: Universal models; these specifications can be installed and used.
Performance air filters are designed for use in modified engine systems to increase airflow, thereby improving performance.
The breather is typically equipped with baffles and filters to prevent oil mist and vapor from clogging the air filter. Vacuum from the intake manifold is applied to the crankcase via the PCV valve, drawing fresh air into the crankcase through the breather.
The sole purpose of a breather filter is to allow clean air to be drawn through the engine block. Without adjusting the velocity density (read: aftermarket ECU), you MUST allow the crankshaft to draw in air after the MAF or AFM, otherwise you'll leave unmeasured air in your engine, making it run lean.
