BMW M5 F90 | Behind-Grille Carbon Fiber Cold Air Intake System

BMW M5 F90 Behind-Grille Carbon Fiber Cold Air Intake System

Engineered for BMW M5 F90 owners seeking to unlock the full breathing capacity of the S63B44T4 4.4L twin-turbo V8, this Behind-Grille Carbon Fiber Cold Air Intake System draws ambient air from behind the OEM kidney grille instead of the hot engine bay, delivering denser, cooler intake charge to the turbochargers. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this BMW M5 F90 carbon intake kit bolts to OEM mounting points with no cutting or permanent modification required.

If you're building a serious BMW M5 F90 tuning project, the behind-grille inlet position significantly reduces intake air temperatures and increases charge density. Paired with appropriate ECU software (tune), it contributes to additional power on the S63B44T4 600-635 hp V8. The carbon fiber heat shield blocks radiant engine bay heat, maintaining a consistently cool intake temperature.

Key Features

• Behind-Grille Inlet Position: Air enters from behind the OEM kidney grille, pulling cool ambient air instead of hot engine bay air.
• Contributes to Power Gains: Adds to output on the tuned S63 V8. Reduced turbo response lag.
• Carbon Fiber Heat Shield: 2x2 twill prepreg carbon construction reflects V8 engine bay radiant heat for stable intake temperatures.
• High-Flow Cone Filter: Washable, reusable performance filter with significantly higher airflow than OEM paper filter.
• OEM Mounting Points: Direct fit to factory airbox bolt locations and hose connections, no cutting, drilling, or bonding.
• V8 Induction Roar: Pronounced V8 intake sound under full throttle. Adds motorsport character.
• UV and Heat Resistance: Clear coat resists fading and cracking at high engine bay temperatures.

Stock Air Filter vs. Performance Air Intake

The OEM stock airbox and paper filter prioritize silence and filtration at factory settings, but restrict airflow at high RPM and allow intake temperatures to rise with engine bay heat. A performance cold air intake:

• Behind-grille inlet → noticeably cooler intake air
• Washable cone filter → significantly higher flow capacity
• Carbon heat shield → prevents engine bay heat from entering intake tube
• With Stage 1 tune: contributes to additional power
• Reduced turbo lag and significantly improved throttle response

Installation Notes

Installing the BMW M5 F90 carbon intake kit is a direct replacement of the OEM airbox assembly. Professional installation is recommended:

1. Open the hood and disconnect the negative battery terminal.
2. Remove the OEM airbox lid and connecting hoses.
3. Align the behind-grille inlet duct to the OEM kidney grille rear.
4. Secure the carbon heat shield to OEM bolt points.
5. Clamp the cone filter to the turbo intake tube.
6. Verify all hose clamps are tight; start the engine and check for leaks.

For best results, a Stage 1 ECU tune is recommended after installation.

Care & Maintenance

The cone performance filter should be cleaned every 15,000-20,000 km using a dedicated filter cleaning kit and re-oiled with filter oil. Wash the carbon heat shield with pH-neutral car shampoo.

FAQ

Will it gain power without a tune?
Yes, turbo response and intake sound improve noticeably even without a tune. The full power contribution is realized with a Stage 1 ECU tune.

Compatible with both standard M5 and M5 Competition?
Yes. This intake fits both 2018-2020 standard M5 F90 (600 hp) and 2019-2020 M5 Competition F90 (617 hp): pre-LCI F90 engine bay geometry is identical across trims.

Is this the same as the BMW M5 F10?
No. M5 F10 (2011-2017) uses a different engine (S63B44T0) and engine bay layout. A separate intake kit for the F10 is available.

Does it fit BMW M3 F80 / M4 F82?
No. M3/M4 F-series uses the S55 engine with a different bay layout. Separate intake kits are available for the M3/M4.

Is the filter washable?
Yes. The cone performance filter is washable and reusable for the lifetime of the kit.

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.
