BMW E46 owners, would you ever do a BMW performance upgrade?

I have a nice 04 325i with most packages except the sports package.



Is it worth getting the BMW performance air intake and suspension upgrades?



They are pricey but can you really feel a difference?BMW E46 owners, would you ever do a BMW performance upgrade?You won't see much performance improvements from air intake mods. 10hp max... hardly noticeable.



But if you like to take corners at high speeds, suspension mods will make the car turn tighter. But you will sacrifice ride quality for that.BMW E46 owners, would you ever do a BMW performance upgrade?I have an E36 with a lot of mods and yes they were worth it. I would spend my money first on suspension and brakes. Just adding a set of springs will make your car much more enjoyable to drive without sacrificing ride quality (they are pretty cheap also). Check out bimmerforums.com and see some of the stuff people have done to their cars, just beware you might become addicted to modifying cars (as I am) and it won't stop. Another good cheap way to get horsepower is with a new chip/ reflash. They are called shark injectors at some places, others reflash the computer. This will be your best hp/$ increase without forced induction.
