I've just fitted my new R8 Oil and Coolant caps and was aware that they say the coolant one touches the sound deadening material but... my bonnet doesn't have any! I'm sure all my previous motors had some. Does everyone on here? Does this mean mine was ripped out at some point? I'm guessing that material also has pretty good heat insulation properties and with the heat from the turbo is the plain metal bonnet OK with that constant engine heat without it? If it is then I'm not bothered. Just interested to know if mine is missing or if it's a "some models have, some models haven't type of thing"?
