The only two I'm aware of is the factory and HK Fevers and neither are painted. You may be able to get HK Fever to paint them for you. I'd worry that it wouldn't match. I know a few owners here have had it panted themselves.
Do you have the ability to paint the scoops if you have the color code?The OEM side scoops are very heavy & thick ( almost 5-7mm ) fiber glass junks, you need to sand them, prime them then paint them.
By the way, OEM was 190.00 GBP a pair a year ago.
