F3X 340 High Flow Air Intake
Designed specifically for the F2x F3X chassis M240 340i 440i (B58), the F3X 340 High Flow Air Intake delivers measurable horsepower and torque gains while sharpening throttle response and producing an aggressive intake tone. Built for performance-minded drivers who demand reliable, streetable power, this intake optimizes airflow to the factory turbocharger for improved transient response and higher peak output.
Key Features
Vehicle fitment: BMW F3X 340i (B58) — engineered to integrate with factory components and OEM mounting points.
Maximum airflow: Large-diameter smooth intake tube and high-flow filter media reduce restriction for better volumetric efficiency throughout the rpm range.
Performance filter: Multi-layer, oiled or dry options available (specify preference). Reusable, serviceable element for long-term value.
Thermal management: Heatshielding and sealed airbox design minimize intake air temperatures and prevent hot-engine reversion, improving consistency under load.
Durable construction: CNC-formed aluminum tubing with wrinkle-black or powder-coat finish for corrosion resistance and factory-quality appearance.
Plug-and-play installation: Uses factory intake mounting locations and sensor ports (MAF compatible), no cutting or permanent modifications required.
Sound: Enhanced intake note—firm, sporty induction sound under throttle without excessive drone at cruising speeds.
Compatibility: Works with stock turbocharger and most common bolt-on upgrades (downpipes, intercoolers). Recommended for use alongside Bootmod3 tuning to unlock full gains.
Performance Benefits
Improved throttle response: Reduced intake restriction improves transient spool behavior from part-throttle to boost.
Peak power gains: Noticeable increases at mid-to-high rpm when combined with supporting mods and ECU calibration.
Consistent power delivery: Sealed design and heat shielding help maintain stable intake temperatures during spirited driving and track use.
What’s Included
High-flow intake tube (powder-coated)

MAF-friendly adapter and sensor fittings
Detailed installation instructions
Installation & Tuning
Estimated install time: 45–90 minutes; moderate mechanical skill recommended.
MAF sensor remains in-line; intake is compatible with stock ECU operation. To maximize gains and ensure safe operation, we recommend Bootmod3 ECU flash and map calibration tailored to your vehicle and hardware combination.
Why Choose This Intake Engineered for real-world performance, the F3X 340 High Flow Air Intake balances airflow and thermal control to deliver reliable power without compromising drivability. Pairing this intake with Bootmod3 tuning and bolt-on supporting hardware unlocks its full potential, delivering a sharper, more responsive driving experience.
Support & Warranty
If you want dyno numbers or a custom-tuned map for your specific setup (downpipes, intercooler, upgraded turbos), contact our tuning team and we’ll tailor a solution for maximum safe gains.
