its just fake HKS oil cap. it should just work fine. i don't think its "crappy" in terms of what its suppose to do. im pretty sure there won't be a problem with the way it works. now if your talking about "crappy" in terms of quality and brand name. yes its a crappy generic oil cap that someone put a fake hks sticker on.
Oh I'm not really trying to spend much for an oil cap. I came across this one and figured hey, maybe its a good cheap cap that will make the engine bay look 1% better, but I guess you really do get what you pay for..especially for supras.
