Why choose the ASM front splitter for the Audi A4 / S4 B9
A front splitter is the first part of the car to meet the air. The ASM carbon fibre splitter for the Audi A4 / S4 B9 lowers the visual stance of the front bumper, sharpens its leading edge and helps manage the air flowing under the nose of the car, so the front end looks more planted at speed.
It is made from real carbon fibre, not a carbon-look wrap or print, so it is light, rigid and shows a genuine woven finish. Read more in our guide to dry vs wet carbon fibre.
Fitting and care
We recommend fitting by an experienced body shop or tuning specialist. Test-fit every part before final installation, prepare mounting surfaces carefully and use the supplied or recommended fixings. Wash carbon parts like the paintwork, avoid abrasive polishes and protect the clear coat with a quality wax or sealant. Step-by-step advice: How to install a front splitter.

The questions
worth asking first
Fitment, installation, materials, lead time and support — the answers that settle the last doubts before you order. Anything not covered, the specialist line is one tap away.
Fitment is defined by the product title, the listed application scope and your platform. If you're unsure, open the WhatsApp line and a specialist will confirm the correct application before you order.
Yes — particularly for carbon aero, exhaust components and platform-specific upgrades, where alignment, finish protection and correct hardware positioning matter to the result.

It depends on whether the part is in stock or built to order. The estimated timeline on the product page is the reference to use before checkout — and the specialist line can confirm it for your exact spec.
Yes. For fitment, visual direction, material choice or build planning, use the WhatsApp block on this page and a specialist will guide you before you place the order.
