The Evo II upgrade adds more capacity and volume to reduce heat soak for the F22 228i/M235i, F30 320i/328i/335i, F32 428i/435i, and F87 M2.
The Wagner Competition intercooler is very similar to their Performance line of heat exchangers for the F22 228i/M235i, F30 320i/328i/335i, and F32 428i/435i 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 - 19lbs vs 25.3lbs. 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 N20 and N55? Not without a bigger intercooler! The stock BMW intercooler on the F22 228i/M235i, F30 320i/328i/335i, F32 428i/435i, and F87 M2 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 N20 and N55 turbo upgrades are not living up to expectations it could be the rest of your system letting your down.
The Wagner Intercooler for the F22 228i/M235i, F30 320i/328i/335i, F32 428i/435i, and F87 M2 is larger to take advantage of the surface area on the front of the F22, F30, F32, and F87. It uses a stepped design to maximize surface area. With more surface area comes more cooling capability and the Wagner has 64% 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 F22, F30, F32, and F87 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.
