Cobra FE Expansion Header Tank

Cobra FE Expansion Header Tank

Re-engineered to visually replicate the original Ford FE brass expansion tanks fitted to Shelby Cobras in the early to mid 60's whilst using modern manufacturing methods to far exceed the quality and longevity of the original tanks.  

OE Spec+ Cobra header tanks are manufactured to suit a Cobra installation.  The tank is set 25mm lower to clear the hood whilst still leaving room for vacuum advance distributors and the radiator hose.  The inlet and outlets are correctly positioned to match an original Cobra tank.

The main tank body, inner level plate, inlet and outlet are made from 1.2mm (16 gauge) 304L stainless steel.  The inlet manifold flange is machined from 10mm (3/8") stainless steel with the larger 63mm (2.5") thermostat recess for improved flow. 

The bracket thickness has been upgraded to 2mm (12 gauge) stainless steel from the original 1.2mm mild steel, to prevent any movement leading to hairline cracks developing.

The whole assembly is then laser welded on a jig to ensure accuracy and a permanently leak free tank.  Each tank is pressure tested to 2.5 Bar (36PSI) before leaving the factory.

Tanks are finished in a satin black polyester powdercoat to match the original factory paint whilst providing much better resistance to degrading/flaking.

Optionally we can supply the tank in raw stainless for customers who wish to either polish the tank or finish to their own colour.  Raw tanks also include a 3/8" outlet spigot pipe that can be welded by the customer into their chosen location.  This was commonly fitted to original cars to help air burp into the expansion tank from the top of the radiator.

Securely packaged for shipping and supplied in an attractive presentation box with 13psi radiator cap, manifold gasket and bolts plus a branded keyring.
