Tracy Lewis Catch Can

Signature Crankcase Evacuation Kit

Stop chasing oil in your intake and start controlling it at the source. This is not a bolt-on catch can—it is a patented, vehicle-specific air/oil separating crankcase evacuation system engineered to help keep your engine running cleaner, longer.

Why Builders Choose the Tracy Lewis System

More Than a Catch Can

Most catch cans simply trap oil. The Tracy Lewis oil catch can kit is a complete crankcase evacuation and separation system that maintains full-time vacuum on the crankcase, addressing pressure issues that passive designs cannot.

Dirty-Side and Clean-Side Coverage

Most kits also include a Clean Side Separator, helping tackle oil-vapour ingestion upstream of the throttle body—a problem standard catch cans do not address. Between the primary separator and the clean-side unit, the system is built to manage oil vapour from both directions of the PCV circuit.

Engineered for Performance and Forced Induction

Designed for performance, modified, street-performance and forced-induction applications, the system is built to help manage valve coking, oil-associated detonation and combustion by-products that can shorten engine life when left to recirculate through the intake charge.

Billet Aluminium Check Valves

Every kit ships with billet aluminium check valves. Running more than 12 psi of boost? Upgrade to a high-performance check valve for the intake-manifold side; the opposite side remains on the standard valve.

Hose Options to Match Your Build

Standard kits use premium Gates Push-Lok hose. For added flow durability or a cleaner under-bonnet look, upgrade to Gates Barricade hose or choose premium black braided hose.

Built for Your Vehicle—Made in the USA

Every Tracy Lewis Catch Can kit is built to order for your specific vehicle, so vehicle information is required before checkout and a short lead time applies. Everything needed for installation arrives in one kit, without universal-fit compromises. Proudly made in the USA.

Know Before You Install

California and some other states restrict certain parts on vehicle emissions systems. Check local regulations before installation to confirm legality in your state.

The Bottom Line

If you are serious about protecting your engine from oil-related buildup and want a system engineered to work with your PCV circuit—not against it—the Tracy Lewis Signature Catch Can Kit is built for your specific vehicle from the ground up.
