The Megan Racing Oil Catch can is a great way to collect the oil that is being recirculated in your intake track. This oil circulation is necessary to pass todays stringent smog laws, but it hurts performance, and if your car is equipped with an intercooler, it can puddle in the intercooler hurting performance even more. The oil catch can helps to collect as much of this oil as possible. The Megan Racing oil catch can is also is drainable, and has a side view so you can see how much oil has collected in the can, informing you of when you need to drain it. Collecting this oil can also help preserve the life of engine sensors that would otherwise get coated in oil.
