The best J&L oil separators in this collection are the J&L Oil Separator 3.0 units for the 2022-2023 Subaru BRZ and Toyota GR86 with the 2.4L engine, in black anodized or clear anodized finish, with matching driver-side separators for the 2005-2020 Toyota 4Runner 4.0L rounding out the range. Check your year and model and the side named in the listing before ordering.
An oil separator, often grouped with catch cans, sits in the engine's crankcase ventilation path and helps collect oil vapor before it travels onward. The listings make the key buying points clear: the separator is side-specific, with passenger-side units for the BRZ and GR86 and driver-side units for the 4Runner, and capacity is part of the product name, designated 3.0. Finish is the other choice, in black anodized or clear anodized.
J&L is presented in this catalog through its Oil Separator 3.0 line, and the products show a focused, application-first approach. The BRZ and GR86 passenger-side separator in black anodized and the same unit in clear anodized differ only in finish, so the decision is visual once the application is confirmed. One 4Runner listing in this collection is titled under the JLT spelling, but it describes the same driver-side Oil Separator 3.0 application for the 2005-2020 4Runner 4.0L.
Two neighboring oil-system names are worth knowing before you buy. Radium Engineering is a broad engineering-led range in this catalog covering fuel and oil-system hardware for many performance cars, useful if you are planning more than one engine-bay upgrade. IAG Performance is the Subaru-focused specialist here, known to WRX and STI owners for engine and air-oil separation products built around Subaru applications. J&L, by contrast, is represented here by a narrow set of finished, vehicle-specific separators rather than a broad hardware catalog.
These separators belong with the rest of your oil-system maintenance, so browse the wider oil system range and keep up with oil filters at service time. The 4Runner option here is the driver-side separator in black anodized, and our guide to bolt-on mods for the Subaru BRZ gives useful context for BRZ and GR86 owners planning supporting upgrades.
Frequently Asked Questions
What does an oil separator do?
It sits in the crankcase ventilation path and helps collect oil vapor before that vapor travels further through the system. These J&L units are vehicle-specific, side-specific separators, not universal cans, so the application in the listing has to match your car.
Which side do I need for my car?
The BRZ and GR86 listings here are passenger-side units, while the 4Runner listings are driver-side units. Order the side named for your application, and check your year and model against the product title before buying.
What is the difference between the black and clear anodized versions?
Based on the listings, the application, side, and 3.0 designation are the same and only the finish differs. Choose black anodized or clear anodized based on the look you want in the engine bay.
Is an oil separator hard to install?
Vehicle-specific separators are designed around a particular engine bay, making them a manageable bolt-on with basic tools. Follow the instructions, route hoses as directed, and check for leaks after the first drives.
