Hi everybody, I am new to here, nice to meet you all!

My ride is a 2004 B6 A4 1.8T S-line, I am going to buy a pair of B6 S4 headlight for her, dunno whether it can be installed and function normally, afraided that there is not enough space in the engine room to install...

Does anyone have such experience (i.e. S4 headlight installed in A4) for sharing? Thank you very much!!

Why are you replacing the ones you have? Also that S-line should already have xenon HIDs..

he has an ultrasport not an s-line.... and yes they do fit and the are slightly largeron thelow beams, meaning they will put out more light and then you will also gain the bi xenon feature too.
