Stop the Leak. Secure the Boost.

If you’re running a late-model EJ25 with the factory plastic-tank intercooler, you know the struggle. The "Diamond" shaped 2-bolt flange is notorious for being a weak point. The factory bypass valves are prone to leaking under increased boost, and finding a high-quality, direct-fit solution for the legendary HKS SSQV has always been a "custom" nightmare.

At Roo Racing, we’ve engineered the definitive fix. Our Billet Alloy SSQV Adapter allows you to bolt the world’s most iconic blow-off valve directly to your factory intercooler flange with zero cutting, zero welding, and zero "she’ll be right" fabrication.

The Roo Racing Difference:

  • Precision Billet Construction: Machined from high-grade alloy to ensure a perfectly flat mating surface against the plastic intercooler tank.

  • The "Diamond" Standard: Specifically engineered for the 2-bolt diamond-shaped flange found on the SH Forester and GR/GV WRX platforms.

  • Boost Integrity: Designed to handle the increased pressures of a tuned setup without the "bleed" common in aging factory valves.

  • "Set and Forget" Reliability: No moving parts to fail—just a solid, specialist-verified link between your intercooler and your HKS hardware.


Confirmed Fitment:

This adapter is a precision fit for turbocharged Subarus featuring the plastic-tank intercooler and "Diamond" flange:

  • Subaru WRX: GE / GH / GR / GV (2008–2014)

  • Subaru Forester XT: SH (2008–2012)

  • Subaru Liberty / Outback: BL / BP (Post-Facelift Turbo Models)


Technical Specifications:

  • Material: CNC Machined Billet Aluminum.

  • Compatibility: Designed for HKS Super Sequential (SSQV) 1, 2, 3, and 4.

  • Hardware: Direct 2-bolt "Diamond" flange mount.

Good Value Replacement Kit for Eufy C20
This accessories kit for the Eufy C20 Omni Robot vacuum includes everything listed in the description. The 8 mop pads are consistent in size and shape. They aren’t quite as thick as the original pads that came with the unit, but they fit well and give me a good supply of clean replacements. With dogs in the house, my Eufy is running almost daily, so that’s a big plus. I haven’t used the other components yet since I had just replaced the bag and cleaned the filters before ordering. I’ll update my review if anything doesn’t fit as expected. For now, I’m comfortable giving this 4 stars — and if 4.5 were an option, that’s what I’d choose. This seems like a solid budget-friendly alternative to the OEM Eufy replacement parts.
