Product Details

Oil Separator Kit by BBK®. With the design of today’s modern fuel injected motors, crankcase oil vapor is sent back through your PCV system and intake resulting in engine sludge and reduced performance. To eliminate this problem and keep your engine performing at optimal levels, these oil separator kits offer a low cost and simple way to pull & catch this engine oil before it enters your intake. Each kit is built from aircraft quality CNC machined aluminum and is anodized to a beautiful titanium gray finish for unmatched looks and quality. Systems are designed to be a direct plug in to your Mustangs current PCV system and come complete with new line and fittings. We also offer a universal kit that will fit most any modern day PCV equipped auto & truck application.

Notes: These Oil Separators are NOT currently CARB approved.


  • Enables O2 sensors on full length, long tube headers to be connected to factory wire harness
  • Eliminates the need to fabricate a harness or splice into the factory harness
  • Includes OEM connectors and heat protective sleeves
  • Simple plug-in installation
  • Works on 3 and 4 wire applications
  • Sold in pairs
  • Limited 1-year warranty
  • Proudly made in the USA

The O2 sensor bungs on full length, long tube headers are usually in the header collectors, locating the sensors much farther rearward than the stock locations, and you'll quickly see that the factory O2 sensor wire harnesses won't reach. Before you resort to fabricating a harness or splicing into the factory harness, get this O2 Sensor Wire Harness Extension Kit.

The kit includes a pair of extensions with factory connectors that will plug right in to your sensors and the factory harness. They'll work on 3 wire and 4 wire applications, however some connectors may require the small directional location tabs to be removed on the ends of the connectors to click into place. Both extensions are also encased in heat protective sleeves to prevent damage.

The O2 Sensor Wire Harness Extension Kit is backed by a 1-year limited warranty against defects in materials or workmanship, as long as the product was installed according to BBK guidelines.
