BMW M3 G80 / M4 G82 Titanium Behind-Grille Cold Air Intake System

Engineered for BMW M3 G80 and M4 G82 owners, this Titanium + Carbon Fiber Behind-Grille Cold Air Intake System draws clean, cool, high-pressure air from behind the front grille directly to the S58 turbo inlet. Manufactured in Europe and quality-controlled by BYC Performance, the system uses titanium for the intake tube and Prepreg carbon for the filter housing.

If you're building a serious BMW M3 G80 tuning or M4 G82 modification project and want a top-tier titanium-aesthetic intake with a power gain on S58, this combo CAI is built for you. It lowers IAT 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

• Titanium + Carbon Combination: Titanium intake tube (low thermal transfer) + Prepreg carbon filter housing (light).
• Power Gain (S58): Significant high-rpm torque and power gains over the stock airbox.
• Behind-Grille Routing: Pulls from the clean, cool, high-pressure region behind the front grille.
• Lower IAT: Noticeably cooler intake temperature than stock.
• 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.
• Titanium Aesthetics: Anodized titanium tube adds top-tier race-look to the engine bay.

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 more volumetric flow, especially above 4,500 rpm.
• Temperature: Behind-grille routing + titanium tube low thermal transfer = lower IAT.
• S58 Power: Noticeable power gain.
• Torque: Mid-range torque improvement.
• Filtration: Performance cotton-gauze filter with a fine filtration barrier.
• 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.

Technical Specifications

• Material: Titanium + Carbon Fiber (titanium tube, prepreg carbon housing)

• Origin: Europe

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 titanium tube + carbon 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 titanium surfaces with pH-neutral car shampoo; never use hydrofluoric-acid cleaners. Clean carbon surface with pH-neutral car shampoo.

FAQ

Compatible with M3 G80, M4 G82 and M2 G87?
Yes. All three share the same S58 turbo inlet and behind-grille volume.

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.

What's the advantage of titanium over a carbon tube?
Titanium has lower thermal conductivity — better insulation against engine bay heat — plus a top-tier visual presence.

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.
