The Crankcase Vent (CCV) Catch Can Kits (11-14 = 20-0279, 15-17 = 20-0287) mount on the front left engine bank of the Mustang GT, as shown below. This catch can runs inline with the crankcase breather port. At low loads it experiences atmospheric pressure, but when the engine is at high load (WOT), this hose will experience high flow out of the crankcase. This would normally lead to oil and sludge accumulation in the air filter intake pipe. If the engine is turbocharged or supercharged oil accumulation can occur in the intercooler which can lower the thermal efficiency properties of the heat exchanger and lead to decreased performance.
Sound tube has been removed in above picture for clarity.
NOTE: There are 2 different kits (20-0279 and 20-0287) simply because of the variation in the vehicle's OEM intake design.
Each kit includes the following:
-Anodized oil catch can with integrated condenser and dipstick
-Anodized laser cut Mustang GT specific mounting bracket
-Anodized aluminum -8AN adapter fittings and hose ends
-Enough 1/2" PCV hose for custom applications
-Stainless steel mounting hardware
