AfterReading Bimmer Mag, I can't help buy wonder why there are so many aftermarket products, one that interest me is called the shark injector it plugs right into the computer which is simmilar to the mercedes computer in the engine compartment and claims that you get 18+ RWHp and only cost 349 USD, has any one seen simmilar products for merecedes, also are there any good mercedes mags I can get, I don't like the idea of chiping my car but this is better because it can be reversed and dosent effect the dealer dianostics plus it a good value if it works

There has to be some aforable ways to boost proformance
