Radium Engineering Catch Can Kits | 2007-2021 Toyota Tundra 5.7L (20-0240-FL / 20-0238-FL / 20-0239-FL)

The 3UR-FE breathes its crankcase straight back into the intake, and 200,000 miles of that leaves a coating you can scrape off.

Radium Engineering Fluid Lock catch can kits for the 2007-2021 Toyota Tundra pull oil and water condensation out of the crankcase gases before they reach the intake manifold, keeping the intake, throttle body, and manifold clean. Cleaner inlet air effectively raises octane, protects performance, and lowers hydrocarbon emissions. The closed system keeps oil vapour out of the cabin. Purpose-built for the 5.7L 3UR-FE with no drilling or permanent modification, and SEMA certified 49-state legal.

Choose Your Kit

• PCV Catch Can Kit (20-0238-FL): single can inline with the PCV valve, catching what gets drawn into the manifold at idle, cruise, and decel
• CCV Catch Can Kit (20-0239-FL): single can inline with the 1/2in valve cover breather port, catching what gets pulled into the intake pipe at wide open throttle
• Dual Catch Can Kit (20-0240-FL): both cans together, Radium's recommendation for complete protection

What You'll Feel

• An intake tract that stays clean instead of glazing with oil film
• On a supercharged truck, an intercooler that keeps its thermal efficiency instead of collecting oil
• Fluid Lock protection: the can cannot overfill and dump contaminants back into the intake
• A bolt-in install with no drilling and no permanent modification
• A closed system that passes tech and does not smell inside the cab

Features

• Patented Fluid Lock system preventing reservoir overfill
• 7 fluid ounce capacity with O-ring sealed dipstick
• Large 10AN ORB inlet and outlet ports, 4AN ORB drain port
• 2-step oil separation baffling with integrated condenser
• Tundra-specific laser cut anodized aluminum mounting brackets
• Anodized aluminum hose ends and adapter fittings with PCV rubber hose
• SEMA certified 49-state legal

The Details

The two circuits catch different things at different times, which is why the dual kit exists. The PCV hose sees metered vacuum at idle, low load cruise, and deceleration, drawing crankcase vapour, unspent fuel, and oil sludge into the manifold right after a hard run. The CCV vent sits at atmospheric pressure at low load but pulls vacuum at wide open throttle, sending the same contaminants into the air filter intake pipe. If the truck is supercharged and you are finding oil in the intercooler, the CCV can is the one that addresses it, since oil coating the core measurably lowers heat exchange efficiency.

The CCV kit ships with two mounting brackets and one goes unused depending on whether the PCV kit is also fitted, so do not assume a missing part. No fixed emptying interval applies: check the dipstick at three to four weeks and set your own schedule, noting that PCV cans usually collect more than CCV cans. Excessive collection points at the engine rather than the can, whether blowby from wear, an over-full oil level causing windage, or a PCV valve not closing under load.

Kit Includes

• Radium Fluid Lock catch can, or two cans on the dual kit
• Tundra-specific laser cut anodized mounting bracket(s)
• Anodized aluminum hose ends and adapter fittings
• PCV rubber hose
• Stainless steel mounting hardware

Applications

• 2007-2021 Toyota Tundra with the 5.7L 3UR-FE engine

Important Notes

• If running a TRD or other aftermarket supercharger, check that intercooler plumbing does not occupy the catch can mounting location before ordering
