MCD Racing RR5 engine heat sink

MCD from Turkey have introduced a new engine heat sink for the RR5 buggy and comparable vehicles. Machined from a single block of 7075 aluminium, the specially shaped heatsink will reduce the temperature at the spark plug by about 10°C, even when run in high ambient temperatures of over 35°C, which results in improved engine performance. The updated heatsink was developed exclusively for the use with NGK CRE8 and CR8EIX spark plugs. In order to protect the cooling head MCD have introduced a composite protector that works with long and short plugs as well as the Barracuda pipe air flow.
