Keep your 1979-2004 Mustang's engine running strong and efficient for years to come with a new Oil Separator Kit (555-3710) from Steeda! An oil separator kit reduces detonation, oil burning and deposits on the valves by removing oil drawn through the PCV system before it can contaminate the intake charge.

Features and Benefits:
- Made in the USA
- Removes Aerated Oil from Re-Circulated Air
- Reduces Detonation, Oil Burning and Deposits
- Plugs into PCV Hose

Kit Includes:
- Oil Separator
- Hose
- All Necessary Hardware

Excess crankcase pressure (sometimes known as "blow-by") is vented from the crankcase through the PCV system, where it is forced into the intake manifold and returned by the engine. This re-circulated air contains aerated oil from the crankcase which is burned by the engine. Nitrous equipped, high mileage and especially boosted engines are prone to excessive amounts of oil into the engine through the PCV system.

Steeda's oil separator kit is designed to plug into your Mustang's PCV hose between the PCV valve and the intake manifold, removing the aerated oil from the re-circulated air and collecting it in a tube that can be drained and recycled.

*This oil separator kit from Steeda will fit all Mustang engines from 1979 to 2004.
