If you own a 2024+ Crosstrek 2.5, then you know how important it is to keep your engine running smoothly. The Crawford Air Oil Separator Baja Edition is the perfect solution to improve engine performance while protecting your engine from harmful contaminants. So, what exactly is an air oil separator?

An air oil separator is a device that separates oil and air from the engine’s crankcase ventilation system. This system is responsible for removing harmful gases, such as blow-by, from the combustion process. However, these gases can contain oil, which eventually settles back into the engine and can cause performance issues if left unchecked. The Crawford Air Oil Separator Baja Edition separates the oil from the gases and prevents it from re-entering the engine.

By preventing oil and contaminants from re-entering the engine, the Crawford Air Oil Separator Baja Edition helps to improve engine life and performance. This is especially important for off-road enthusiasts who push their engines to the limit in demanding environments. By reducing the amount of oil in the engine, you’ll also see improved fuel economy and reduced emissions.

The Crawford Air Oil Separator Baja Edition is a high-quality and durable device that is specifically designed for the 2024+ Crosstrek 2.5. It is made from high-quality materials that can withstand the harsh environments often encountered in off-road conditions. The easy-to-install design means you can have the benefits of improved engine performance and protection in no time.
