Eventuri Carbon Fibre/Fiber Performance Intake for BMW 3 Series G20/G21 B48 2.0 Turbo - Cold Air Intake Induction Kit & Carbon Airbox Upgrade (318i 320i 330i 330e incl xDrive, V1/V2 MAF/IAT)

Transform the way your BMW 3 Series breathes with the Eventuri carbon air system for the 2.0 turbo petrol models. Designed specifically for the G20 saloon and G21 touring with the 318i, 320i, 330i and 330e powertrains including xDrive, this premium carbon assembly delivers a cooler, cleaner and less restrictive airflow path from the filter to the turbocharger. Expect sharper throttle response, quicker spool and a deeper induction tone, all while elevating your engine bay with a show-stopping pre-preg carbon finish.

At MJ Modifications we have installed and used these on customer vehicles and our own cars. Fit and finish are outstanding, the sound is addictive and drivability gains are instantly noticeable. If you are looking for a high-end intake upgrade that works on the road and stands up to heat on track, this Eventuri solution is the one we recommend.

Highlights and benefits

• Sealed carbon airbox with dual fresh-air feeds - isolates intake charge from under-bonnet heat and draws ambient flow from the factory duct plus an additional wheel arch route for consistent temperatures.
• Gold reflective barrier - targeted heat shielding on the exhaust side helps combat radiant soak for repeatable performance in traffic and on spirited drives.
• Smooth-bore carbon intake tube - large diameter, gradual taper and minimal turbulence for stable MAF readings and efficient turbo efficiency. V1 up to 111 mm ID. V2 109 mm ID at the filter end.
• High-flow dry cone filter - ISO-tested media, washable and non-oiled, with an internal flow cone to maximise filtration area and streamline airflow.
• OEM-level fitment - CNC machined sensor mountings, laser-cut brackets and quality fixings for a straightforward, plug-and-play install.
• 100 percent pre-preg carbon fibre - lightweight construction with a smooth internal surface and a premium aesthetic under the bonnet.

Why this upgrade works

• Cooler intake charge - a fully sealed housing and twin cold feeds help maintain lower intake temps compared to open cone setups.
• Lower restriction - increased airbox volume and a large-bore tube allow the turbo to draw air with less effort for crisper response.
• Cleaner airflow path - removing the convoluted factory pipe reduces turbulence, supporting smooth and repeatable flow to the compressor inlet.
• Refined sound - enjoy a subtle turbo whistle and deeper induction note without excessive cabin drone.

Version guide: V1 vs V2

BMW revised the factory inlet tube after November 2018. Please choose the correct version for your sensor type:

• V1 - for cars built before November 2018 that use a MAF sensor in the intake tube. Larger tube up to 111 mm internal diameter at the filter end.
• V2 - for cars built after November 2018 that use a temperature sensor in the intake tube. Large tube with 109 mm internal diameter at the filter end.

Quick check: if your factory inlet has a MAF sensor choose V1. If it has an air temperature sensor choose V2.
