Audi B9 S4/RS4 S5/RS5 Carbon Fiber ECU Cover ECS Tuning Catalyst as the original intake hoseProduct Details The B9 range of the S4 S5 and RS4 RS5 are packed full of styling details and are often fitted with aftermarket carbon fibre induction kits and engine covers, but on every car we saw one thing stood out, the factory ECU spoiling the look under the bonnet so here at ECS we decided something needed doing about this!
