Ramair PRORAM Intake Kit with Carbon Lid BMW 1/2/3/4 Series B58

Ramair PRORAM Performance Intake Kit with Carbon Fibre Lid – BMW 1, 2, 3 & 4 Series B58 (PRK-249-BK)

This intake kit from Ramair is designed as a direct replacement for the restrictive factory air intake on BMW models fitted with the B58 3.0-litre turbocharged petrol engine. By improving airflow into the engine, it helps unlock performance that the standard setup often holds back – delivering sharper throttle response, a more engaging induction note, and improved breathing for the turbocharger.

The PRORAM pleated filter sits at the heart of the kit. Pleated filters use a folded filter media to increase the total surface area available for air to pass through, meaning more air flows more freely compared to a standard paper filter. Combined with the 90mm intake pipe and heat shield enclosure, the engine receives a stronger, cleaner charge of air – exactly what a turbocharged engine benefits from.

What’s Included

• PRORAM pleated performance air filter
• Carbon fibre lid
• Black powder-coated heat shield
• Black powder-coated hard pipe
• Black silicone reducer
• Black silicone coupler
• Full fitting hardware and step-by-step instructions

Key Features

The 90mm intake diameter is matched precisely to OEM MAF sensor dimensions – the MAF (Mass Air Flow) sensor measures how much air enters the engine, and maintaining the correct sizing here ensures the engine management system reads accurately and runs correctly with no need for remapping in standard form.

The carbon fibre lid adds a clean, purposeful look under the bonnet while keeping the intake enclosure lightweight. Combined with the powder-coated heat shield, the filter is kept isolated from hot engine bay air as much as possible, helping maintain a cooler, denser air charge.

Installation is straightforward and uses the full hardware kit provided. Most home mechanics with basic tools should be able to fit this without specialist equipment, though if you are unsure it is always worth having a professional carry out the work.

Important: This kit is designed specifically for BMW B58 3.0-litre turbocharged petrol engines. Fitting to incorrect engine variants may result in poor fitment or sensor incompatibility. Always confirm your exact model and engine code before purchasing.

This kit is suitable for the BMW 1 Series (F20/F21), 2 Series (F22/F23), 3 Series (F30/F31), and 4 Series (F32/F33/F36) fitted with the B58 engine, covering models including the 140i, 240i, 340i, and 440i from 2016 onwards.
