I am approx 7 degrees above ambient when driving at 50mph recently. Yesterday I saw 62 degrees sat in traffic. Tempted to line the air bucket in gold tape now tooMine stays 2c above ambient temp and that's in the current weather with a gigantic intercooler sat next to it ! Actually works a charm.
I was half tempted to wrap the sides in gold heat tape to try and force the temps down that smidge more. Because we all know, FI needs that cool dense air.
If i was rebuying mine i'd probably go red on both sides with the LED's lol! Alas i've just got drivers side in black
