Heat riser insulation kit

The pre heat tubes of the intake manifolds near the engine plating guide is sealed by means of 2 plates, foreseen of insulation to prevent that the heat of the engine underneath the vehicle can run through the engine compartment.  After many years of service this insulation material has become fragile and does no longer seal properly.  From now on BBT can deliver from stock the insulation material in a set suitable for all engine based on Type 1 from 08/60 except for AR 1300CC engines.
