i got one on ebay from hyper industries, for like 80 bucks works... it justsuppose to let more fuel go to the fuel rails i think... i really dont think you need it until you get a lil bit more stuff such as headers cam or more serious engine work...its suppose to compensate by adding more fuel because the mods are sucking up more fuel...something like that... go on ebay... youll find some there i got one from an accord i think or prelude...cant remember
