EDDYSTAR Carbon Fiber Intake Kit for BMW X1 F49 sDrive18Li 20Li B38 B48 1.5T 2.0T 2016-2019 Air Intake System
Product Details
Carbon Fiber Intake Kit BMW X1
,B38 B48 Air Intake System
,2016-2019 BMW X1 1.5T 2.0T Intake
The EDDYSTAR Carbon Fiber Airbox Intake System is engineered specifically for the BMW X1 F49 (2016–2019) sDrive18Li and sDrive20Li, covering both the B38 1.5T and B48 2.0T turbocharged engines. It replaces the factory airbox with a sealed prepreg carbon fiber enclosure and smooth-bore intake tube, targeting the heat-soak issue that reduces intake air density on turbocharged engines during sustained driving.
| Feature | Detail |
|---|---|
| Carbon Fiber Airbox (CF-R) | Sealed prepreg carbon fiber enclosure; thermal conductivity approximately 1/40th that of aluminum, blocking heat transfer into the intake charge. |
| High-Flow Mushroom Filter | Washable and reusable; maintains filtration while increasing airflow. |
| Third-Generation Vortex Design | Scientific smooth-bore pipe reduces resistance and increases flow. |
| Lossless / In-Situ Installation | Direct bolt-on to factory mounting points; no modification required. |
| Good Heat Resistance | Integrated thermal barrier inside the carbon airbox. |
- Power gain: Up to +10 HP with a 20–30% increase in airflow, per EDDYSTAR's own product specification for the X1 EY-CFR-BM06.
- Throttle response: Improved low-to-mid range response due to reduced intake restriction.
- Sound: Enhanced induction note without highway drone.
- Acceleration reference: EDDYSTAR's intake testing on a Mazda 3 1.6 AT (catalogue page 23) showed a 1.53-second reduction in 0–100 km/h time (16.30s → 14.77s), demonstrating the acceleration benefit of the sealed carbon airbox design.
| Chassis | Model | Engine | Year |
|---|---|---|---|
| F49 | X1 sDrive18Li | B38 1.5T | 2016–2019 |
| F49 | X1 sDrive20Li | B48 2.0T | 2016–2019 |
Also compatible with F48 X1 sDrive18i / sDrive20i (2016–2022) and F39 X2 sDrive18i / sDrive20i (2018–2022) where the same B38/B48 intake layout applies.

- Installation Guide
No ECU tuning required — compatible with factory DME programming.
OE reference for filter replacement: 1371 8513 944 (current) / 1371 7619 267 (old). Cross-reference: MANN C22018, MAHLE LX4060, PURFLUX A1719, BOSCH F026400461.
Fitment confirmation: This intake is designed for B38 1.5T and B48 2.0T only. It is not compatible with B48A20T1 (X1 M35i / X2 M35i) or B47 diesel variants. Please provide your VIN if unsure about your engine variant.
Will this carbon fiber intake fit my 2010–2012 VW Golf 6 1.6L?
Yes. It is designed specifically for the VW Golf VI (5K1) with the 1.6L EA111 engine (2010–2012). It fits the 1.6L petrol and BiFuel (LPG) variants. Direct bolt-on fit with factory mounting points.
Does it require ECU tuning?
No. It works with the factory ECU. No remapping of ECU or DME is required. A custom tune can maximize gains but is not necessary.
What performance gains can I expect?
EDDYSTAR CF-R series carbon fiber intake systems have been independently tested to deliver up to 12% horsepower gain over the stock airbox, with improved air density and fuel efficiency. On a 1.6L naturally aspirated engine, this translates to a noticeable improvement in throttle response and top-end pull. Gains vary by fuel quality, altitude, and supporting mods.
Will it fit other VW/Audi 1.6L models?
Yes. It also fits VW Golf 6 Variant (AJ5) 1.6L, VW Jetta 1.6L, and other PQ35 platform models with the EA111 1.6L engine. Some models may require minor modification.
Will it trigger a check engine light?
No, if installed correctly. The MAF sensor housing is designed to factory specifications. Always reconnect the sensor properly.
How do I clean the filter?
Use a cold air intake cleaning kit. The filter is a washable, reusable high-flow design. DNA Filters' equivalent for this platform offers 98–99% filtration efficiency. Clean every 30,000–50,000 km depending on driving conditions.
Is installation difficult?
It is a direct bolt-on job using factory mounting locations. Basic hand tools are enough. Installation takes about 60–90 minutes. Professional installation is recommended.
Does it increase intake sound?
Yes. The carbon fiber intake system delivers a more pronounced induction note, especially at higher RPM. The sealed airbox design keeps the sound refined and reduces unwanted intake drone at highway speeds. The carbon fiber construction also acts as a thermal barrier, keeping intake air cooler and denser.
What is the factory OE part number?
The main air filter OE number is 1K0 129 620 D (or 1K0129620D). Also compatible with 1K0 129 620 E, 1K0 129 620 L, 1K0 129 620 ZC, 1K0 129 620 C, and 5C0 129 620. This helps confirm fitment.
What warranty do you offer?
Limited 2-year warranty against manufacturing defects. Does not cover improper installation or racing use.
