I haven't seen anyone post about intercoolers, so I don't know if they don't do much or if I just overlooked the discussion. Just wondering how much of an improvement in egt's temps these really do. I think Banks is the only one that has one specific for the 6.7 right now, but I wonder if the 5.9L one's are any different. I already have the water/methanol injection, but anything that is maintenance free is nice. Give me your thoughts. Thanks.
