There's been talk around here about intake runners making a noise like that. I get it at times and I think it's fuel related. I have found a couple stations that I can buy their 87 octane and not have any problems...but others I get knocking. 91 octane is recommended for maximum performance (see owners manual). If I can't buy from the stations I know work well...I buy the 93 octane.
