The J&L JLT3084D-B Oil Separator 3.0 is designed for the driver side of select 1997-2013 Chevrolet and GM trucks and SUVs equipped with 4.8L, 5.3L, 6.0L, or 6.2L engines. During crankcase ventilation, oil vapor can travel through the intake system, where it may collect in the intake tube and manifold runners or reduce fuel octane. This issue can become more pronounced in supercharged and turbocharged applications because of increased crankcase pressure. The J&L oil separator helps reduce the amount of oil vapor routed back into the intake.
