AVO Turboworld Dual Breather Tank Kit
2013–2016 Scion FR-S, 2017–2018 Toyota 86, 2013–2018 Subaru BRZ
S6Z12G0QBRACT
Overview:
The AVO Turboworld Dual Breather Tank Kit is a precision-engineered solution designed to protect and enhance the performance of your Scion FR-S, Toyota 86, or Subaru BRZ’s engine breathing system. Specifically developed for these popular sports cars, this kit effectively manages crankcase gases by separating oil mist from the blow-by gases before they re-enter the engine’s air intake. This prevents oil contamination in the combustion chamber, reducing the risk of detonation and maintaining optimal engine health under high boost and high RPM conditions.
Ideal for enthusiasts who push their vehicles on the track or run higher boost levels, the AVO Dual Breather Tank Kit addresses the limitations of the stock PCV system, ensuring reliable operation during demanding driving scenarios. By improving crankcase ventilation, it helps maintain engine efficiency and longevity, especially in forced induction applications.
Key Features:
This comprehensive breather tank kit offers a range of features designed to optimize crankcase ventilation and protect your engine:
- Oil/vapor separator tank that removes oil mist from crankcase gases before routing them back to the intake system
- Turbo-specific high-pressure PCV valve replacement to prevent boost leaks and avoid crankcase pressurization under boost
- Secondary breather tank vented to atmosphere to handle heavy venting demands typical of circuit racing
- Oil filler cap replacement that allows direct routing of excess oil from the turbocharger oil reservoir back into the engine
- Complete kit with all necessary fittings and accessories for a seamless installation
- Designed to alleviate oil overflow issues during extended high RPM use on the track
- Protects against detonation caused by oil entering the combustion chamber
- Essential upgrade for higher boost builds and forced induction setups
Construction & Design:
The AVO Turboworld Dual Breather Tank Kit is crafted with durability and performance in mind. The oil separator tank is engineered to withstand the rigors of high-pressure crankcase gases and elevated temperatures common in turbocharged engines. The included PCV valve is specifically designed to handle boost pressures without leaking, ensuring the crankcase remains properly ventilated without pressurization. The oil filler cap replacement is precision-machined to facilitate efficient oil return, preventing overflow and maintaining clean engine operation during aggressive driving.
Every component is manufactured to meet strict quality standards, ensuring long-lasting reliability and compatibility with the factory engine bay layout of the Scion FR-S, Toyota 86, and Subaru BRZ.
