VekAuto PCV Valve Hose Connector for Subaru OE 11821AA660 — Aluminum, OEM-fit for Forester Impreza Legacy WRX BRZ Crosstrek Outbac

VekAuto No.11821AA660 is an aluminum PCV valve hose connector engineered to replace the factory fitting on many Subaru engines, restoring proper crankcase ventilation and preventing leaks.

This precision-machined connector replaces worn or damaged PCV hose fittings on a wide range of Subaru vehicles, including Forester, Impreza, Legacy, WRX, BRZ, Crosstrek, Outback and XV models listed under OE 11821AA660. Built from corrosion-resistant aluminum and manufactured to exact dimensions, the part is intended to match OEM fit and restore reliable routing of crankcase gases back into the intake for combustion. The description below explains compatibility, materials, installation considerations and the performance benefits you can expect when replacing a degraded connector.

Which Subaru models and years will this connector fit?

This VekAuto connector is designed around OE number 11821AA660 and fits a selection of Subaru models across multiple years. Confirm compatibility by comparing your vehicle’s part number and the connector’s shape to the pictures before purchasing.

• Fits Subaru BRZ (2013–2024) and Crosstrek/XV Crosstrek (2013–2024 ranges noted).
• Compatible with Forester (2011–2015), Impreza (2012–2024), Legacy and Outback (2013–2019).
• Also fits WRX and WRX STI from 2015–2016 where the OE number matches.

How does this connector affect engine ventilation and performance?

The connector keeps the PCV routing sealed and directs blow-by gases toward the intake so they can be burned in the combustion cycle rather than vented to atmosphere. That controlled routing helps maintain steady crankcase pressure and supports consistent combustion behavior.

• Restores sealed path for crankcase gases to the intake manifold.
• Helps reduce unmetered air and potential rough idling from leaks.
• Aids in maintaining emission-control behavior tied to PCV routing.

What materials and features make this connector durable?

Manufactured from robust aluminum, the connector resists corrosion and wear typical in under-hood environments. Precision dimensions and a strong finish help prevent loosening, leaks and premature failure under engine vibration and elevated temperatures.

• Aluminum construction for corrosion resistance and long life.
• Precision machining for tight, reliable sealing with hoses and fittings.
• Designed to withstand engine heat, vibration and repeated service cycles.

What should I know about installation and what’s included?

The package contains one VekAuto PCV valve hose connector; installation generally requires hose removal and inspection of clamps or seals. If you’re unsure about the procedure, consult professional tutorial videos or a mechanic to avoid incorrect installation that could cause leaks or poor performance.

• Package includes one PCV valve hose connector (no additional hardware).
• Compare photos and OE number 11821AA660 to confirm fit before ordering.
• Replacement may require basic hand tools and careful hose clamp handling.

Who this part is for: drivers, DIY enthusiasts and professional technicians working on compatible Subaru models who need a direct-fit, corrosion-resistant replacement for a failing PCV hose connector. Choose this connector if you see symptoms of cracked fittings, vacuum leaks or want to restore original ventilation routing using a durable aluminum replacement matched to OE 11821AA660. If you have any doubt about fitment or the replacement process, check your vehicle’s parts diagram or seek a professional installer to ensure a correct and safe repair.
