Ive been noticing a large increase in the number of blown knock sensors and engines and head gaskets in the past month or so. Why is this? Did a lot of people turn it up a pound or are boosting hard on hot days? I suspect the summer heat may have something to do with it. Any ideas? Do people run into detonation more often this time of year than winter?
