Wagner Evo II Competition Front Mount Intercooler (FMIC) - Z4 35i
Greater capacity to further reduce heat soak
The Evo II upgrade adds greater capacity and volume to further reduce heat soak.
The Wagner Competition intercooler is very similar to their Performance line of heat exchangers for the E89 Z4 35i/35is but has a lighter construction for better performance on track.
The Competition intercooler is built with a tube and fin layout which trades surface area for lighter weight. Tube and fin designs have fewer channels for the air and thinner materials. This makes the entire unit lighter - 14.5lbs vs 19.8lbs. There is less heat soak capability so this is not the best intercooler for traffic jams but cools just as well when driving at speed. Where pounds count and the car is always moving - such as in a race environment - the Competition intercooler is the better option.
Ready for more boost in your N54? Not without a bigger intercooler! The stock BMW intercooler on the E89 Z4 35i/35is is decent enough for maintaining intake air temps on a stock engine (though there's still room for improvement). But adding more boost will raise intake air temps and lead to fuel and timing adjustments that could actually reduce power levels! If your N54 turbo upgrades are not living up to expectations it could be the rest of your system letting your down.
The Wagner Intercooler for the E89 Z4 35i/35is is larger to take advantage of the surface area on the front of the E89. It uses a stepped design to maximize surface area. With more surface area comes more cooling capability and the Wagner has 85% larger area for 60% more air volume compared to the stock intercooler. CAD and FEA design has optimized the air flow into and out of the heat exchanger thanks to turbulator fins, cast aluminum endtanks, and model-specific silicone hoses. There is less pressure drop than stock which means air velocity stays high.
One of the best attributes of Wagner intercoolers is their direct fit installation on the E89 models. The bumper does not have to be removed or modified and the Evo II fits with any chargepipe desgined for the stock intercooler. Wagner uses a durable anti-corrosive coating that also helps dissipate heat. Installation instructions are included.
