As stated in the thread I was curious if an s4 bumper would work with an a4. I'm assuming it will bolt right up but will I have to relocate my fog lights or anything else. Any help is much appreciated.

 

so if you have a B7 ya gotta be careful. An S4 bumper will work but if you don't have an S-line you'll need to get a new grill too (the S4 bumper has a wider grill). Its good to know in advance so you don't get that "we need to order a new grill"-call from your body shop. There are a ton of types and aftermarket grills that you can choose from so its good to know whats out there and do your homework in advance.
