The universal application of this oil catch can means that it can fit into a variety of car models, making it a versatile option for many users.

One of the standout features of the EVIL ENERGY Oil Catch Can is its generous 300ml capacity. This allows for ample collection of oil, preventing it from re-entering the intake system and causing potential damage. The design includes a 31.5-inch hose with a diameter of 3/8″ for the inner dimension and 2/3″ for the outer dimension, providing flexibility in installation while ensuring a secure fit.

This is a small but significant maintenance tip that ensures the oil catch can operates effectively and extends its lifespan.

In my experience, investing in an oil catch can like the EVIL ENERGY model can yield substantial long-term benefits.
