I have heard some dodgy stories that a few people who have fitted a bigger intercooler had to modify the bonnet catch, and the bonnet has flipped open when giving it stick on the motorway
Yep it does happen..... I think when I go down the large intercooler road I will get rear bonnet raisers to help let the heat out more and install bonnet pins for good measure. As much as I don't want to cut my bonnet about I wouldn't risk it any other way
