# Audi S4: PPF, Ceramic Coating & Sport Sedan Accessories
**Paint Protection Film (PPF):** Protect your S4's subtle yet potent design with high-grade self-healing PPF. The S4's front bumper, full hood, fenders, and headlights are the most vulnerable areas, and specialists recommend wrapping edges to avoid visible seams. For daily-driven S4s, a **Full-Front package** (bumper, hood, fenders, mirrors, headlights) is the standard choice, while track enthusiasts often opt for **Full-Body PPF**. Pre-cut DIY kits are available specifically for the S4 (2019-2026), including front bumper, headlights, fenders, hood, mirrors, and rear bumper options. Choose TPU-based film with self-healing properties and 99.9% UV blocking. Self-healing nano-technology erases swirl marks with heat, resisting bug splatter, tar, and bird dropping etching while preserving resale value.
**Sun Film & Window Tinting:** Nano-ceramic tint is the preferred choice for the S4's cabin, blocking over 99% of UV rays and approximately 60% of heat without interfering with electronics. Vehicle-specific precut tint kits are available for the S4 sedan (2009-2016) and Avant (2015-2024), covering all side and rear windows. **India Compliance:** The Supreme Court's ban on aftermarket sun films remains strictly enforced. Adhere to **70% VLT front/rear and 50% sides**, or use magnetic sunshades for parking. Verify current regulations with your local RTO.
**Ceramic & Graphene Coating:** Applied **over PPF** for maximum protection, ceramic coating enhances gloss, makes washing easier, and protects against insects, bird droppings, and dirt. Professional-grade products like Cquartz require baking to fully bond to the paint. Annual maintenance of both PPF and ceramic coating is recommended—inspection of film edges and application of a hydrophobic booster restores surface performance and keeps maintenance simple. The combination of **PPF + Ceramic Coating** is the gold standard for S4 protection.
**Genuine Audi Accessories** include illuminated S door sills with aluminum inserts, Sport S seats with diamond stitching, and a multifunction leather Sport steering wheel with S badge and contrast stitching. The S4 Avant offers up to **1, 435 litres** of cargo space with rear seats folded.
