buy a cheap shitty valve cover.. cut that one so you can tune them , then put your valve cover back on once they are tuned.. unless you want to be the guy who is like "hey look at my adjustable cam gears!!"
i had a black one, im not too sure what happened to it lol......
u should put a black one one the type r. then when people want to race you show em and be like its a b16.
i think im gonna get a black one for tuning, and maybe the winter too, when the salt kicks up it gets on top of the engine and leaves white spots, and its a pain to get off, plus I do most of my work in the winter, so im always scared to scratch it up. the tenzo r finish is pretty durable.
