• CNC-machined for a precise, leak-free fit

Opening Up Real BOV Options

The factory turbo setup on this platform isn't designed to directly accept a TiAL-style blow off valve, which is one of the more popular and well-regarded aftermarket BOV options among Subaru owners. Torque Solution's adapter bridges that gap, letting you bolt a TiAL BOV directly onto the factory location without cutting, welding, or fabricating a custom solution. That's a meaningful convenience for anyone who's chosen a TiAL valve specifically for its reputation and wants a clean, factory-location install. That's exactly the kind of thoughtful design worth paying for.

CNC Precision for a Leak-Free Seal

CNC-machined rather than cast, this adapter is built to seat precisely against both the factory turbo inlet and the TiAL valve, minimizing the leak risk that a poorly fitted adapter can introduce under boost. A boost leak at this connection point can genuinely hurt performance and throw off tuning, so getting this fitment right matters more than it might seem. It's a small part that makes a real difference in how cleanly the whole intake system comes together. For a component this critical, that level of engineering is worth having.
