Airtec Motorsport Cosworth Group A Oil Separator & Catch Tank
A Group A-spec oil separator and catch tank for the Cosworth YB, helping modified engines breathe better and giving up an easy source of extra power once the engine is properly set up — replacing the original breather system, which was only ever designed around a standard 215bhp car.
Unlike the fast road separator, which vents from a breather outlet on its underside, the Group A version routes that breather to the catch tank instead — essential on big-power Cosworths, since it catches any oil the separator can't cope with under high boost, rather than letting it spray around the engine bay. The catch tank is styled as a mirror image of the water header tank and sits around the left-hand suspension turret.
