1KD Coolant Block Outlet Adapter – AN Style

HPD Special Parts Adapter for Forward-Facing Intake Manifolds

If you're running a forward-facing HPD intake manifold on your 1KD, this adapter is a must. It replaces the factory coolant outlet and allows you to neatly run a 90° AN-style fitting—stopping fouling issues caused by the intake piping.

Made for custom setups and clean engine bay finishes, this adapter helps you get your coolant lines tucked and flowing exactly where they need to be.

Perfect Fit For:

• 1KD-FTV engines with HPD Lobster or Silver intake manifolds
• Custom builds requiring coolant reroute clearance
