Speaker Insulation Rings, 4.2 E-Type Console. Sold Per Pair. E-Type speaker grilles are very shallow, meaning most speaker cones will actually hit the grille unless the proper spacers are used. We've reproduced a slightly thicker version of the factory part that provides the proper clearance. Most originals are missing or one step away from dust. These do not fit 3.8 E-Types as they have smaller-diameter speakers. Manufactured by XKs Unlimited.
