hello, i drive a 330i sp(step, euro) and im planning to install an intake and an exhaust in the future. i just have a few questions in hope that someone could help out.
do i need to do anything to the computer after i install an intake and/or an exhaust? (in order for the car to adjust)

what is the best mod for the car (in terms of increasing horsepower) keeping in mind that i dont live in the us?

thanks

neither one will require you to do anything to your ecu and I think that intake probably gains more power if you get the right one.

i was thinking of the K&N intake? what do you have and what do you recommend?

I have the gruppe m which uses a k&n filter. I love the gruppe m and personally would not have gone with anything else, it is pretty pricey though...

does it increase horsepower? is it proven by any dyno?

i had actually installed an OMP filter, it gave the car a little extra sound, thats all and then the car started stalling ,so i took it off immediately and put the original back in, thats the reason for my initial question about the ecu, i had suspected that the cars ecu rejected it or something.

The Gruppe M is dyno proven at something like 6rwhp gain and 9 lft/lbs
