Has anyone heard of cutting the front under arch cover to allow more air to pass over the inter coolers and disc brakes? It would appear to force the air straight through the coolers and then onto the brakes disc and pads, instead of exiting out of the side vents or through the small slits in the original cover. It has also been noticed that the oil temp. does not go above 95, even when pushed very hard. Is this normal, as my old S4 used to get up to 120 when given a good tonking?
