VS Catch Can Kit for Toyota Supra (B58)
As power levels increase, the factory crankcase ventilation system on the B58 begins to reach its limits. Higher boost and increased cylinder pressure generate more blow-by gases, carrying oil vapor back into the intake tract. Left unchecked, this oil vapor coats your intercooler, charge pipes, intake manifold, and intake valves, while also contaminating the air entering the combustion chamber.
One of the most overlooked effects of oil vapor is its impact on fuel quality. Oil has a much lower effective octane rating than premium gasoline. When oil vapor mixes with your air/fuel charge, it reduces the mixture’s resistance to knock, effectively lowering the octane available to your engine. On high-horsepower and built B58 engines running aggressive boost and ignition timing, this can increase knock activity, cause the ECU to pull timing, and reduce overall performance.
The VS Catch Can Kit is designed to separate oil from crankcase vapors before they re-enter the intake system. By removing oil from the airflow, it helps preserve fuel quality, maintain octane performance, and keep harmful oil contamination out of your engine.
Why It’s Essential for Built B58 Engines
Built B58 engines naturally generate more blow-by due to increased cylinder pressure, larger turbochargers, higher boost levels, and tighter ring sealing. While blow-by is a normal byproduct of making big power, excessive crankcase pressure and oil contamination can quickly become reliability concerns.
A properly designed catch can system helps:
- Prevent oil vapor from entering the intake tract
- Help preserve the effective octane of your air/fuel mixture
- Reduce knock potential under high boost
- Help the ECU maintain optimal ignition timing
- Keep intercooler piping, charge pipes, and the intake manifold cleaner
- Reduce carbon buildup on intake valves
- Maintain proper crankcase ventilation under demanding conditions
- Reduce the likelihood of oil leaks caused by excessive crankcase pressure

Built for Performance
Whether your Supra is a daily driver, weekend street car, or a 1,000+ horsepower race build, proper crankcase ventilation is one of the most important reliability upgrades you can make. The VS Catch Can Kit helps keep oil where it belongs—not in your intake system—so your engine can make the most of the fuel you’re putting into it. Cleaner intake air, preserved octane, reduced knock potential, and improved long-term reliability all add up to a smarter solution for any performance-focused B58 build.
Protect your investment. Preserve your octane. Keep your B58 performing at its best.
