Hi all ive searched for this for about an hour and cant find what i need. I bought the ebay insys intake for gen1 ls. I want black couplers instead of the blue ones but am worried about the paint peeling and the exposure to engine heat. Can I paint the blue couplers black? Any recommendations on how to paint them or what kind of paint to use? Or, is there a place I can buy the couplers in black, I've checked all 3 of my local auto parts stores and had no luck finding them in black.
