One of the most common maintenance upgrades for the Subaru boxer engine is the addition of a proper air/oil separator. The primary problem is that harmful oil and vapors will make it through the factory's PCV system and into the intake manifold. This can coat the intake valves and the tops of the pistons with carbon. This will also lower your fuel's octane rating which will lead to detonation issues that will cause misfires, and premature engine wear. We carry a great selection of air/oil separator kits only brought to you by the best brands in the industry to prevent oil and vapors from entering your intake system to prolong the life and performance of the EJ in your Subaru WRX or STI.
