      Don't Dilute your Octane Levels. During the process of venting crankcase pressure back through your intake, large amounts of oil vapors can coat your intake tube and even dilute your gas, lowering its octane level. This happens in all engines, but even more so with forced induction systems. To combat this, JLT has developed the all new Version 3.0 Oil Separator. The V3.0 Oil Separator holds over double the old version. 3 ounces of fluid might not sound like much, but drain it every 5000-7000 miles and you won't come close to filling it. It also features a new multi stage filter designed to collect the finest of vapors.

      Lasting Quality. Milled from solid billet aluminum, the JLT has a knurled tank base for easy removal when draining the spent oil, and an O-ring seal to prevent leaks. Filtering is done by a fine mesh stainless steel screen that traps fine oil vapors. They then pass through a 1/2" thick 1/16" aluminum honeycomb filter where oil collects before dropping into the 3oz tank. JLT then completes their Catch Can in a durable black anodized finish for aggressive good looks and long lasting corrosion resistance.

      Easy Installation. JLT Performance engineered their Separator to be installed in under 30 minutes with just basic hand tools. This kit comes complete and includes two PCV lines with stock-style quick-disconnect fittings that allow for an easy plug-and-play installation. All the necessary parts are included with no cutting or extra modifications required.

      Not CARB Certified. This JLT Performance Air/Oil Separator is not CARB certified at this time; therefore, it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

      Application. This JLT Performance Version 3.0 Black Driver Side Air/Oil Separator is designed for use on 2012-2018 3.6L Jeep Wrangler JK models.

        Oil Catch can

        This oil separator has been amazing. I've noticed a huge gain in MPG which is something I did not know would happen. About a 3 MPG gain which is a lot for a wrangler. Every 3k miles I check it and its definitely doing its job. Great product. The only negative thing is its a super tight fit.

        Very nice set up

        I love it but they could make some improvements I found a 90 degree house and attached it instead of pinching the line off as it bent and if you have a 15 wrangler you have to find a long bolt to attach it mine had a pop USB pin holding on

        Great Catch Can

        Great fit and finish. Good placement as it leaves room on the driver side engine bay for a Rough Country MLC-6 switch panel (which I plan on in the future). Only complaints are that the lines are barely long enough to manhandle under the intake tube and install them. One of the lines rest on top of the alternator as well which is a concern if it gets too hot.

        Definitely works.

        This product works as described. I'm amazed at how much oil is actually collected. My motor has 15000 miles on it.

        JLT air/oil seperator

        I love the product and it performs perfectly. There is one problem, it should come with one 45° elbow for the inlet hose. Only then, will it fit perfectly.

        Great Quality

        This is well built with very light materials. Super easy install. Hard to tell minor performance changes without a dyno, but mpg seems to be up slightly.
