Wagner Tuning BMW E89 Z4 EVO 2 Competition Intercooler Kit

Colder charge temps for your E89 roadster

Transform the way your Z4 pulls with this uprated front mount charge cooler. Designed for serious airflow and dependable intake temperature control, this EVO II unit delivers a genuine step up in efficiency and performance consistency for spirited road use and track days.

Why enthusiasts choose this upgrade

• Stepped high-efficiency core measures 520 x 210 x 150 mm, a substantial increase in frontal area and internal volume over the factory unit for stronger cooling headroom
• Approximately 85 percent more face area and about 90 percent more internal capacity than stock, helping reduce heat soak and stabilise intake air temperatures
• Low restriction design for excellent airflow and noticeably reduced pressure drop compared with the OE cooler
• Competition-grade lightweight core around 7.4 kg, balanced for rapid heat transfer without excess mass
• CAD-optimised cast aluminium end tanks, engineered using flow analysis to minimise bottlenecks and ensure smooth, uniform distribution
