its mugen... its like why do people pay $100 on some nikes. Your paying for the name. and look how much money i spent on this valve cover. not worth it to me... id rather keep the stock valve cover and throw that $800 to something that will improve the performance of the engine
it's all about being real...why get the fake stuff....i'm sure if you preferr doing engine preformance, i don't think you would wanna buy some cheap knock off parts...eventho they might preform the same..
