Intake

Ok so I have an intake question.... my friend was going to put an intake on his car, but when he went to the dealership they said not to get one because living in South Florida it is very humid and it rains a lot. With that being said he told my friend not to get the intake because the moisture will get sucked up through the intake and into your engine and cause you even more problems. I was just wondering if this was true or not and also what are some good brands of intakes to get for a Bmw?

Rims

I just put new rims on my 2003 325i. I was just wondering if by putting on rims, it will void my warranty at my dealership? Will this affect if they will do tire rotation and balance? here is a site to check out the rims (I got them in 18") http://customwheel.com/custom_wheels/images/DeltaForce_black.jpg

Door Trim

I have been having an issue with the door trim on my car. It keeps coming loose whenever I open my door, I have taken it to the shop about three times to be fixed and the shop fixes it, but it only lasts about three weeks and then it comes loose again. I'm just wondering if I need to get the whole door trim replaced rather than just the part that is loose? Also, Would not having the door trim at all cause water to leak inside the car?

Tires

I just realized the other day that the tread on my tires is really low and am probably due to get new tires soon. Does anyone know of a good brand of tire to get that are in the 600-700 dollar range? I was looking at some Bridgestones but they are pretty pricey. Also I forgot to mention my tire size is 225/40/zr18.

Sound System

Does a closed off trunk with a sound system prevent less sound from coming up to the cabin of the car as opposed to a hatchback trunk where the trunk is inside the car?

Exhaust

Ok so I have been wanting to add an exhaust onto my 2003 Bmw 325i. I have researched a little bit and stumbled across an exhaust made from Active-autowerkes. It is a company based out of Miami and they make all Bmw aftermarket parts. here is the link to the site. Check it out and tell me what you think of it or just tell me of any exhusts that you have heard that sound nice on a Bmw.http://www.activeautowerke.com/viewproduct.aspx?id=Product25 (it is the video at the bottom of the page).
