I don’t think anyone is saying it’s not safe for the engine, it’s definitely not good that the knock sensors are off the rails, but it’s more just that someone would spend money on so many upgrades but leave the intercooler alone. Especially if you live in the south lmao.Y'all haven't lived until you've seen 80-100F temp rise during a 3rd gear pull on an OG 1.8T car on factory intercooler. OE intercooling is much better now than in those days. Not saying go out and do track days...but for a true street driven car, it'll be safe
