Stainless 316 ecu speaker cone

Made of high quality stainless 316 and machined by ourselves.

These  speaker cones fit both ECU's R-Plus and super +  and  have been machined at a 0.02 mm tolerance .

The cones do fit ECU's MK1 compact bite alarms, but must then be attached with a small piece of double-sided tape or clear sealant. Also the cone protrudes compared to the R and Super plus series.
