Product Description

The HKS 11999-AT001 is a purpose-built oil pan for FA20/FA24-powered Toyota 86, GR86, and Subaru BRZ platforms running an HKS GTIII-RS Bolt-On Turbo kit. It replaces the stock oil pan with a version that already has the oil return pipe fitted, removing a major step from the turbo installation process.

The return pipe connection is welded on both the inside and outside, and a reinforcing bracket is added at the joint to guard against leaks under sustained boost. A durable painted finish helps the part hold up over long-term daily or track use, making it a practical companion piece for anyone installing the matching HKS turbo kit rather than a standalone upgrade on its own.
