Oil
Catch Can.

The RacingLine Oil Catch Can System for the B9 Audi V6T S5/S4/SQ5 EA839 engine uses a series of internal baffles in both the breather plate and the catch tank itself to keep your inlet tracts clear of oil residue.

Brace
yourself.

In all of our B9-platform R&D work, it has become very clear that whilst the laser-welded body is very stiff and well reinforced, handling will always benefit from a sharper, stiffer bodyshell.

So, our beautiful B9 Billet Body Brace for all A5, S5, RS5 tightens up the weakest point on the car between the top suspension mounts, replacing the flimsy factory version.

 

All with no drilling or cutting.
