Best Evo X Catch Can Kits

There’s a lot of debate on whether or not you should install a catch can on your Evo X. While there’s an argument for and against, the real answer comes down to how you drive and the kind of mods you’re currently running.

If you have a high boost Evo X and want to push it to its limits, fitting an oil catch can is an important safety upgrades for your engine.

In this guide, you’ll find everything you need to know, along with the best Evo X catch can kits to control excess oil and protect your engine from damage.

Do I Need a Catch Can for My Evo?

During combustion, pressure from the piston pushes combustion gas as well as small amounts of oil and fuel past the piston rings and into the crankcase. This is commonly referred to as “blow-by.”

To keep the crankcase from excess pressure and robbing the engine of power, blow-by is pulled from the crankcase via positive crankcase ventilation, or a “PCV” system and sent back into the intake.

Of course, oil and fuel are not what you want in your air intake.

While the factory crankcase ventilation/PCV system works fine on a stock or moderately modified Evo X, it does have its limits. Excess power or simply an aged PCV system can mean more and more oil and fuel vapors reach your intake.

The OEM PCV valve is the first part that’s prone to leaking, which inevitably leads to increased pressure in the crankcase and also makes it harder for oil to return back to the pan.

A quality catch can helps reduce crankcase vapors along with the amount of accumulated oil in the intercooler and intake piping, and turbocharger of your Evo X.
