07 RS4 interior compatibility
 

Can someone confirm 07 RS4 headliner and abc pillar covers will fit 04 A4, pretty much everything at and above shoulder level. I am wanting to black out the interior.

The Audi RS4 and Audi A4 belong to different model lines, and even though they may share some components, there could be differences in dimensions and design between the two models. This can affect the fitment of parts like the headliner and A-pillar covers. Additionally, if the RS4 and A4 you're comparing are from different generations (e.g., B7 RS4 vs. B6 A4), there may be further differences in interior dimensions and design, making parts interchangeability less likely.

Before purchasing any parts from an Audi RS4 for your A4, it's advisable to compare the specifications and dimensions of the components you're interested in or test fit the parts or consult with a knowledgeable mechanic or automotive specialist who can provide insight into compatibility and any modifications required for proper installation. Additionally, consider reaching out to Audi enthusiast forums or online communities where members may have experience with similar swaps and can offer guidance based on their firsthand knowledge.
