BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber Cold Air Intake System

Engineered for BMW M3 G80 and M4 G82 owners, this Prepreg (Dry) Carbon Fiber Cold Air Intake System replaces the OEM airbox entirely with an autoclave-cured carbon fiber tube and integrated enclosed filter housing. Manufactured in Europe and quality-controlled by BYC Performance, the system feeds cool air directly to the S58 turbo inlet.

If you're building a serious BMW M3 G80 tuning or M4 G82 modification project and want an OBD-friendly airflow upgrade on S58, this Prepreg carbon CAI is the ideal choice. It reduces the high-rpm airflow restriction and improves turbo response on the new-generation S58-powered M3/M3 Touring/M4/M4 Convertible family (473 hp standard, 503 hp Competition, 543 hp CS/CSL).

Key Features

• Prepreg (Dry) Carbon Fiber: 2x2 twill carbon, autoclave-cured. Very high strength for its weight and high heat resistance.
• Power & Torque Support (S58): Smoother high-rpm air delivery versus the stock airbox.
• Integrated Enclosed Filter Housing: Isolates the filter from hot engine bay air — keeps IAT low.
• OEM Sensor Compatible: MAF and IAT sensors install in factory positions — no OBD codes.
• Washable Performance Filter: Cotton-gauze multi-layer filter, cleanable for lifetime use.
• Full OEM Connections: Bolts directly to turbo inlet and airbox mounting points — plug & play.
• Show-Quality Look: Transforms the engine bay with high-gloss carbon weave surfaces.

Stock Filter vs. Performance Intake — What's the Difference?

The OEM airbox uses a paper filter and narrow plastic channels — creating air starvation at high rpm on the S58. The performance intake:

• Airflow: Noticeably higher airflow than the stock airbox, especially at high rpm.
• Temperature: Enclosed filter housing isolates from engine bay heat.
• S58 Power: High-rpm power support from opening up the turbo inlet restriction.
• Torque: Improved mid-range torque feel.
• Filtration: Washable performance cotton-gauze filter.
• Sound: Pronounced turbo intake + dump-valve sound.

Vehicle Fitment

• BMW M3 G80 Sedan (2021, 2022, 2023, 2024, 2025, 2026) — S58 engine (473 hp)
• BMW M3 Competition G80 (2021+) — S58 (503 hp)
• BMW M3 CS G80 (2023+, limited) — S58 (543 hp)
• BMW M3 Touring G81 (2022+) — S58 (503 hp)
• BMW M4 G82 Coupé (2021+) — S58 (473/503 hp)
• BMW M4 CSL G82 (2022, limited) — S58 (543 hp)
• BMW M4 G83 Convertible (2021+) — S58
• BMW M2 G87 Coupé (2023+) — S58 (460 hp)

NOTE: The previous-generation BMW M3 F80 / M4 F82 (S55) uses a different turbo inlet and airbox layout — NOT compatible. BMW M2 F87 (S55) is also NOT compatible.

Installation Notes

1. Turn off the engine and allow it to cool.
2. Remove the OEM airbox cover and main hose.
3. Carefully label and remove the MAF and IAT sensors.
4. Install the new carbon intake tube + filter housing on OEM mounting points.
5. Attach MAF/IAT sensors to the new tube (torque: 4-6 Nm).
6. Tighten clamps (3-5 Nm) and check for air leaks.

Care & Maintenance

Wash the performance filter with cotton-gauze cleaner and re-oil every 15,000-20,000 km. Clean the carbon surface with pH-neutral car shampoo; apply carbon-safe sealant every 6 months.

FAQ

Compatible with M3 G80, M4 G82 and M2 G87?
Yes. All three share the same S58 turbo inlet and airbox layout.

Will this throw an OBD code?
No. The MAF and IAT sensors install in OEM positions.

Does it require a tune?
No, it works stand-alone. A custom tune can extend the gains further.

Compatible with previous-gen F80 / F82?
No. The S55 engine uses a different turbo inlet and airbox layout.

Can the carbon housing handle engine heat?
Yes. Autoclave prepreg carbon withstands engine bay temperatures.

Shipping time?
In-stock items ship within 1-3 business days via partner couriers.

Warranty?
BYC Performance offers a 12-month manufacturer warranty against production defects.
