Audi R8 4S (Type 4S) 5.2L V10 Restyling & Engine Tuning (CSPA)
The Audi R8 4S (second generation, 2015–2023) with its legendary 5.2L V10 naturally aspirated engine is a prime candidate for restyling and performance upgrades. While “CSPA” isn’t a recognized Audi engine code or tuning package (it may refer to a specific custom project or local tuner), here’s a comprehensive guide to restyling and enhancing the R8 4S’s engine and aesthetics:
Engine Tuning & Performance Upgrades
The 5.2L V10 FSI (FSI engine code: CZPB/CZVA) is already a masterpiece, but enthusiasts often push it further:
- ECU/TCU Remapping:
- Stage 1: Bump power from 602–620 hp (stock) to 630–650 hp with optimized throttle response.
- Stage 2: Combine with exhaust/intake mods for 660–680 hp (e.g., MTM, ABT, or APR tunes).
- Stage 3: Forced induction (rare for NA V10) or hybrid turbo kits (custom builds only).
- Exhaust System Upgrades:
- Valvetronic Cat-Back Systems: Brands like Akrapovič, Capristo, or IPE offer lightweight titanium systems with adjustable sound profiles.
- High-Flow Catalysts/Headers: Unlock ~15–20 hp gains and sharper throttle response.
- Intake & Throttle Body:
- Cold Air Intake (CAI): K&N or Eventuri carbon-fiber intakes improve airflow.
- Larger Throttle Bodies: Custom upgrades for marginal gains (limited by NA design).
- Weight Reduction:
- Replace OEM seats with carbon-fiber buckets (save ~44 lbs/20 kg).
- Lightweight wheels (e.g., HRE, BBS FI-R) and lithium-ion batteries.
- Suspension & Brakes:
- Coilovers: KW Clubsport or Öhlins TTX for track-focused handling.
- Carbon-Ceramic Brakes: Upgrade to Audi’s OEM carbon ceramics or aftermarket kits from Brembo.
