VRSF Front Mount Intercooler FMIC Upgrade for BMW Z4 E89 sDrive35i/35is (2009-2016) N54 Twin Turbo - Performance Charge Air/Charge Cooler, 5in Stepped, 7.5in Competition Stepped & Race, Direct Fit Bolt-On

Give your E89 roadster the cool, dense charge it deserves. This front mounted charge air cooler is a serious cooling upgrade for the twin turbo N54, delivering repeatable power on the road and track, sharper throttle response and safer ignition timing under sustained boost. Expect stronger pulls, reduced heat fade and rock solid reliability from stock turbos through to big-power builds.

Why enthusiasts choose this FMIC

• Massive reduction in intake air temperature for consistent performance during back to back acceleration
• Prevents heat fade that the small factory unit struggles with once boost and airflow are increased
• Designed for direct fitment on the E89 chassis with all hardware included
• Proven on customer cars and record-breaking builds

Performance options to suit your build

5 inch Stepped HD - perfect for OEM turbochargers and fast road use. In our experience this unit typically shows around a 4 degree rise during a single third-gear acceleration where the stock cooler can climb by roughly 30 plus degrees. Ideal for remapped and full bolt-on setups needing a dependable, budget friendly solution.

7.5 inch Competition Stepped HD - for tuned and hybrid turbo applications. Proven to support up to around 850 whp with only about a 2 degree increase in charge temps during a third-gear sweep. Thanks to a denser fin pack and larger frontal area it can even finish multi-gear pulls colder than it started. If your budget stretches, this is the one we recommend for future headroom.

7.5 inch Race core - the choice for builds targeting power figures beyond 850 whp.

Engineering that keeps power in the car

• High density bar and plate matrix tuned for excellent cooling with minimal pressure drop
• 3D CAD designed cast aluminium end tanks for smooth airflow and superior durability versus multi piece or sheet end tanks
• Bright silver corrosion resistant finish to handle UK weather and road debris
• More robust than the OEM tube and fin unit so it can take the punishment of daily use

Fitment and installation

• Direct fitment for 2009 to 2016 BMW Z4 E89 sDrive35i and sDrive35is with the N54 twin turbo engine
• Retains the factory fan shroud tabs and includes model specific moulded silicone couplers plus stainless T bolt clamps
• Typical install time around 2.5 hours
• 5 inch stepped unit - usually no cutting of the black plastic ducting, some cars may need light trimming
• 7.5 inch stepped units - trimming of the black plastic shroud behind the bumper is required, no bumper cutting
• Suitable for both right hand drive and left hand drive vehicles

Every unit is hand finished and pressure tested for a leak free result. Backed by the manufacturer’s lifetime warranty for peace of mind.
