BMW M3 F80 / M4 F82 | Prepreg Dry Carbon Fiber Cold Air Intake System

BMW M3 F80 / M4 F82 Prepreg Dry Carbon Fiber Cold Air Intake System

Engineered for BMW M3 F80 and M4 F82 owners, this Prepreg (Dry) Carbon Fiber Cold Air Intake System (CAI) replaces the restrictive factory airbox with a high-flow, heat-insulated dry carbon enclosure. Autoclave-cured by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW F80 / F82 carbon cold air intake dramatically improves how the S55 engine breathes.

For drivers who want to unlock the potential of the S55B30T0 twin-turbo previous-generation M3/M4 lineup (425 hp standard, 444 hp Competition, 460 hp CS, 493 hp GTS), this dry carbon cold air intake delivers a noticeable power gain and improved throttle response. Induction sound also increases significantly. Plug & play: no ECU tune required.

Key Features

• High Flow: Wide-throat carbon airbox eliminates the restrictive OEM geometry.
• Power Gain: Noticeable power increase on the S55 engine.
• Improved Throttle Response: Faster turbo spool and a more linear power curve.
• Induction Sound: Distinct turbo intake and blow-off character.
• Heat-Shielded Carbon Enclosure: Keeps engine bay heat out of the intake; true cold-air feed.
• OEM MAF/MAP Sensor Compatibility: Existing sensors transfer; no tune required.
• Prepreg Dry Carbon Construction: Autoclave-cured, more homogeneous weave, race-grade strength.

Stock Air Filter vs. Performance Intake: Why Upgrade?

The factory S55 airbox is a sealed plastic enclosure drawing from a hot engine bay; flow is restricted and filter surface area is limited. A performance air intake system brings:

• High-flow conical filter + wide-section carbon box → a noticeable power gain on the S55
• Faster turbo spool, more linear power curve
• Distinct turbo induction noise
• Heat-insulated carbon enclosure for genuine cold-air feed
• Plug & play: no ECU tune required

Installation Notes

Installing the BMW F80 / F82 carbon air intake takes 60-90 minutes:

1. Disconnect the battery.
2. Remove the OEM airbox lid and intake tubes.
3. Transfer the OEM MAF/MAP sensors to the new carbon box.
4. Bolt the carbon airbox to the engine bay using OEM mounting points.
5. Connect the intake tube to the turbo inlet and tighten clamps (8-10 Nm).
6. Reconnect the battery, start the engine, and check for leaks.

Care & Maintenance

Clean and re-oil the conical filter every 15,000 km using filter-specific cleaner. Wash the carbon enclosure with pH-neutral shampoo. Do not aim a pressure washer directly at the box.

FAQ

Does it need an ECU tune?
No. The system is plug & play and requires no ECU changes. However, paired with a Stage 1+ tune it delivers additional gains.

Can I use the OEM air filter?
No. The carbon box is designed for a high-flow conical filter; the OEM panel filter does not fit.

Compatible with G80 / G82?
No. G80/G82 (2021+) use the S58 engine with different intake geometry.

Compatible with M2 F87?
Only the S55-engined M2 Competition F87 (2018-2021) is supported. Standard N55-engined M2 (240i) is not.

Compatible with M2 G87?
No. G87 uses the next-gen S58 with a different intake design.

Compatible with F83 Cabriolet?
Yes, BMW M4 F83 Convertible (S55) fits perfectly.

Will it affect my car's factory warranty?
OEM sensors and connections are preserved, and installation is fully reversible. Whether it affects your car's factory warranty depends on the car maker's terms. In the US, fitting an aftermarket part does not by itself void the factory warranty, but the car maker can still refuse to cover damage it shows the part caused.

Shipping & warranty?
In-stock items ship within 1-3 business days via partner couriers. Parts sourced to order are delivered within 30 days of the order date at the latest. Manufacturing defects are covered by a 24-month BYC warranty, in addition to your legal rights.
