Pair (2 pieces) of 10mm Cloth woven genuine bakelite spacers to suit 48 DCOE & 48 DCO/SP Weber carburettors. This material is the best to use in Automotive applications and will significantly decrease heat transfer from manifold to carburettor. A gasket is required either side of the spacer. Multiple spacers can also be joined together to increase height further. CNC Machined finish. Sides of spacers can be easily painted to suit any application. Bakelite is very absorbant to paint and will hold permanently.
