If you know Cadillac performance, you already know the LF3 and LF4 aren’t just engines, they’re legendary twin-turbo V6 platforms that respond to power like few others. But with that performance comes a problem most people overlook… oil contamination.

Direct injection doesn’t clean the intake valves. Add boost, and now you’ve got oil vapor and blow-by getting pushed right back into the intake system. Over time, that means carbon buildup, reduced efficiency, and lost performance.

That’s where this system comes in.

What This Catch Can Does

Under boost and even normal driving conditions, your PCV system is constantly cycling oil vapor back into the intake.

This catch can stops that cycle.

It separates and captures oil, fuel vapor, and contaminants before they can reach your intake valves. Clean air continues through the system, while the junk gets trapped in the can.

Simple. Effective. Necessary.

Why It Matters on LF3 & LF4 Engines

These engines make power. And when you start pushing them, whether stock or tuned, blow-by increases.

More boost = more contamination.

Without a catch can, that buildup:

  • Coats intake valves
  • Reduces airflow and efficiency
  • Lowers octane through oil contamination
  • Increases the chance of knock

This system helps prevent all of it.

Built the Right Way

This isn’t a universal kit with cheap internals.

This is purpose-built.

  • Proper baffling for real oil separation
  • High-quality lines and fittings
  • Clean, straightforward installation
  • Designed to integrate with factory systems

It works. And it keeps working.

The Bottom Line

If you’re running an LF3 or LF4, you’re sitting on one of Cadillac’s best modern performance engines.

Protect it.

A catch can isn’t just another mod, it’s a smart upgrade that keeps your engine cleaner, safer, and performing the way it should every time you hit boost.
