Cusco 1H1 009 A Street Oil Catch Tank Kit for 2023+ Toyota GR Corolla

The Cusco 1H1 009 A Street Oil Catch Tank Kit is engineered specifically for the 2023+ Toyota GR Corolla (GZEA14H) with the G16E-GTS 1.6L turbocharged engine. This performance-enhancing component intercepts harmful blow-by gases before they can reenter the combustion chamber, protecting your engine from oil and carbon buildup that robs horsepower and degrades performance over time.

How It Works:

During normal engine operation, blow-by gases containing oil mist, fuel vapors, and moisture escape past the piston rings and exit through the valve cover via the PCV (Positive Crankcase Ventilation) system. Instead of allowing these contaminants to recirculate back into the intake manifold where they can coat intake valves, damage sensors, and reduce combustion efficiency, the Cusco catch tank traps and separates them. This results in cleaner, more efficient combustion and extends engine life—especially critical for direct injection engines like the GR Corolla's turbo powerplant.

Key Features:

• 0.6-liter (600ml) oil capacity tank with polished aluminum construction
• 15mm inner diameter clear hose allows visual monitoring of oil accumulation
• Vehicle-specific bolt-on installation designed for the GR Corolla engine bay
• Includes all mounting brackets, hoses, and installation hardware
• Mirror-polished finish with signature Cusco blue anodized fittings
• Easy-access drain system for convenient maintenance

Benefits:

• Prevents oil and carbon deposits on intake valves and in intake manifold
• Protects MAF sensors and turbocharger components from contamination
• Maintains optimal air-fuel ratios for consistent power delivery
• Reduces detonation risk and improves throttle response
• Essential upgrade for modified or high-boost applications

This catch tank kit is particularly recommended for enthusiasts planning engine tuning, increased boost pressure, or frequent spirited driving. The generous 0.6L capacity means less frequent draining compared to smaller universal units, while the vehicle-specific design ensures proper fitment and optimal PCV system integration without the guesswork of universal kits.

Note: Designed for competition and off-road use.
