JLT

The best JLT parts for a 2016-2021 Infiniti Q50 or Q60 3.0T are the two Oil Separator 3.0 units in this collection, both listed for the driver side: one in black anodized finish and one in clear anodized finish. They are the same application in two finishes, so the right choice is simply the finish that suits your engine bay.

An oil separator sits in the crankcase ventilation path and is designed to separate oil vapor from the air being drawn back toward the intake, collecting the oil in a canister instead of letting it pass through. On a turbocharged engine like the 3.0T, that makes it a popular maintenance-minded upgrade. Fitment details matter here: both units here are driver-side pieces for the 16-21 Q50 and Q60 3.0T only, so check your year and model before ordering, and browse the supporting systems in Oil System and Nissan / Infiniti.

JLT is represented here by one focused product done two ways, which makes the comparison straightforward. The Oil Separator 3.0 is named for its application and side, and the black anodized and clear anodized versions let the owner choose a discreet or a more visible finish without changing the listed fitment. This is a separator piece for a specific turbocharged platform, not a universal can, and that platform-specific listing is what to look for.

Four related brands frame the wider intake and engine-bay picture. Radium Engineering is known for precision fluid-handling components, including fuel-system and catch-can style hardware engineered around specific applications. Mishimoto built its reputation on cooling, with radiators and intercooler-related parts. K&N Engineering is best known for air filtration and intake systems. aFe Power also concentrates on intake and airflow products; compare its range in Air Induction.

What does the JLT Oil Separator 3.0 do on the Q50 or Q60?

It is designed to separate oil vapor from crankcase ventilation air on the driver side of the 16-21 Q50 and Q60 3.0T, collecting oil in the separator instead of letting it continue toward the intake. It is a maintenance-minded engine-bay part, not a power adder.

What is the difference between the black and clear anodized versions?

Based on the product titles, the application is the same: Oil Separator 3.0, driver side, for the 16-21 Infiniti Q50/Q60 3.0T. The listed difference is the finish, black anodized versus clear anodized, so choose by appearance preference.

Does an oil separator need emptying or maintenance?

A separator that collects oil has to be checked and emptied as part of regular maintenance, with the interval depending on driving conditions. Follow the product instructions for how to inspect and drain your specific unit.

Will this fit other Infiniti or Nissan models?

The listing names only the 2016-2021 Q50 and Q60 with the 3.0T engine, in driver-side form. Other models, engines, or sides are not covered by these titles, so check your year and model before ordering instead of assuming cross-fitment.
