Radium Engineering Catch Can Kit CCV Fluid Lock Toyota Tundra 07-21

CCV Catch Can Kit comes with 2 mounting brackets. One bracket will be disregarded depending if the PCV kit will also be used. The crankcase vent runs inline with the 1/2" valve cover breather port. At low loads it experiences atmospheric pressure, but when the engine is at high load (WOT), this hose will experience vacuum and would normally be drawing unwanted crankcase vapors, unspent fuel, and oil sludge into the air filter intake pipe. If the engine is turbocharged or supercharged and you are finding oil accumulation stuck in the intercooler, this catch can is a necessity as oil will lower the thermal efficiency properties of the heat exchange process.
For the ultimate in engine protection, Radium recommends the Tundra 20-0240 Dual Catch Can Kit (shown below) which utilizes both the "Crankcase" catch can and "PCV" catch can.
