Honda Civic IACV (Idle Air Control) Relocate

Works with all D and B series engines, and may fit some H and F series as well.
Used for turbo applications and aftermarket intake manifolds that require alternative IACV placement or a check valve to prevent boost surge during throttle cut. Can also just be used for aesthetics (tucked engines)
If you are 3D printing and not machining, the manifold side should still be backed with a hardened plate to prevent blowout if this is a boosted engine.
