FD Racing stocks aftermarket parts for the Audi A4 across its five generations, from the original B5 through to the current B9. The turbocharged TFSI and TDI engines respond well to induction and exhaust upgrades, and S4 and RS4 owners will find uprated parts to match their higher power output.

For engine performance, browse induction kits, intercoolers, blow-off valves and exhaust systems. Handling upgrades cover anti-roll bars, coilovers and strut braces built for the A4's front and quattro all-wheel drive platforms, with brake kits for fast road and track use.

Fitment tags on each product let you filter to your exact generation and engine before buying. All parts are priced in GBP including VAT. Free UK delivery on orders over £200.
