Advertising sells a lot of stuff that most people don't really need. There are a lot of young guys out there that don't have a lot of extra money to spend. I hate seeing them getting sucked in to spending a lot of money that really needs to be spent elsewhere on their cars. Unless yu have some radical engine setup, factory stuff will do the job. It has always worked for me.
