some people charge more than what the part actually costs to produce. this allows them to do business and resell or sell the product and ship...etc....then again, you get what you pay for...its like 2 dollar sandles at target...or 30 dollar sandles at some other store...which one will last longer? however...the apex-i BOV's are fine...read below on some posts...BOV's are basically about sound, and thats it...(other than being able to push huge PSI numbers) ...but apex-i...should do just fine
