⚠️ Crucial Model Application, Accessory & Hot Box Fitment Notes:
1. Delco Air Conditioner Clearance: If your vehicle is equipped with a factory-optioned large-body Delco Air Conditioning Compressor unit, this part (A213) will conflict structurally with the mounting bracket lines. You must use Part No. A85B instead to ensure safety clearances under the engine bay layout paths.
2. No Hot Box Variant Requirements: This base product comes with standard Hot Box provisions for factory intake manifold preheating. If you are running aftermarket multi-carburettors (e.g., Triple Webers or twin side-draught systems) or specialized manifolds that do not utilize a pre-heat intake loop, please order Part No. A213NHB (No Hot Box variant) for a clean look.

Please Note: Professional installation by an exhaust specialist or qualified classic vehicle mechanic is highly recommended to guarantee proper system mapping and a perfect gas-tight seal.
