BMW M5 F90 | Prepreg Dry Carbon Fiber Cold Air Intake System

BMW M5 F90 Prepreg Dry Carbon Fiber Cold Air Intake System

Engineered for BMW M5 F90 owners, this Prepreg (Dry) Carbon Fiber Cold Air Intake System redesigns the intake side of the S63B44T4 4.4L twin-turbo V8 for high airflow, contributing to power gains with a supporting tune. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this BMW M5 F90 carbon air intake kit mounts directly to the OEM airbox locations with no harness cutting required.

If you're building a serious BMW M5 F90 tuning project and need a part that goes beyond the stock paper-filter box, delivering lower intake temperatures and a clean torque-curve improvement, this dry carbon cold air intake system is built for you. The carbon fiber housing isolates intake air from the heat-soaked V8 engine bay; high-flow performance filters supply cool, clean air to both banks. Engineered for the 600-635 hp output of the F90 M5.

Key Features

• High-Flow Performance Filters: Twin conical washable performance filters; noticeably more airflow vs OEM paper elements.
• Prepreg (Dry) Carbon Airbox: Cured under high temperature and pressure; isolates intake from V8 bay heat.
• Power Gains: Contributes to power and torque gains with a compatible Stage 1/2 tune.
• Sound Character: S63 V8 turbo intake and waste-gate character become more audible; exhaust note unaffected.
• Direct OEM Fit: Mounts to factory F90 M5 (pre-LCI) airbox bolt points; MAF sensor connectors are preserved.
• Washable Filters: Cleanable and re-oilable elements for long-term service life.
• Carbon Weave: Exposed surfaces in 2x2 twill, high-gloss UV-protected coating.

Stock Air Filter vs. Performance Air Intake

The OEM airbox is designed for cost and noise: paper filter elements, restrictive ducting, and a plastic box increase intake temperatures and restriction. A performance air intake:

• High-flow washable cotton/gauze filter → lower restriction, more airflow
• Carbon box insulation → lower intake air temperature (IAT), higher turbo efficiency
• Power and torque gains with a Stage 1/2 tune
• More audible turbo intake and spool character
• S63 V8 bay temperatures are high, making heat shielding critical

Installation Notes

Installing the BMW M5 F90 carbon air intake system consists of removing the OEM airbox and installing the new one. Professional installation is recommended:

1. Disconnect the battery negative terminal.
2. Remove the OEM airbox cover and filter elements; disconnect MAF connectors.
3. Remove the stock airbox from the engine bay.
4. Mount the carbon airbox to the OEM points; reconnect MAF sensors.
5. Install the high-flow filters on both sides.
6. Reconnect the battery and drive 50-100 km to allow the ECU to adapt.
7. Combine with a Stage 1/2 ECU tune for maximum gains.

Care & Maintenance

Clean the carbon surface with pH-neutral shampoo. Wash and re-oil the filter elements according to the manufacturer's service interval (~20-30k km). Do not direct pressure-washer spray onto the filter during engine bay cleaning.

FAQ

Can I use it without a tune?
Yes. With the stock ECU map you'll get a more aggressive intake sound. For full potential, a Stage 1/2 tune is recommended.

How does it add power?
It contributes to power and torque gains with a compatible Stage 1/2 ECU tune.

Does this fit the F90 LCI (2021+)?
The LCI airbox is mostly shared with pre-LCI, but we recommend the LCI-labeled version in our catalog when available.

Compatible with both standard M5 and M5 Competition?
Yes. The S63B44T4 engine uses the same airbox geometry across F90 standard and Competition trims.

Does it fit the BMW M5 F10?
No. M5 F10 (2011-2017) uses a different airbox and engine harness.

Does it fit BMW M3 F80 / M4 F82?
No. M3/M4 (S55, S58) inline-6 engines have different intake geometry.

Will it affect my car's factory warranty?
A cold air intake is a hardware upgrade. 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. An ECU tune may also affect the factory warranty.

Shipping time?
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.

Warranty?
Manufacturing defects are covered by a 24-month BYC warranty, in addition to your legal rights.
