COMPETITION INTERCOOLER KIT BMW F80-82-83 M3/M4 The 3.0 Liter S55B30 turbo engine from BMW M3/M4 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is realized by a watercooled intercooler which will be replaced by this WagnerTuning high-performance intercooler. The WAGNERTUNING high-performance intercooler has got a new competition core (Tube Fin) with the external core dimensions 287 mm x 185 mm x 115 mm / 11,3Inch x 7,3Inch x 4,5Inch. This intercooler core was directly developed for the high requirements of the BMW M3/M4 and offers 114 % more external core volume compared to the stock intercooler. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and at the same time the best possible internal air flow. The aluminum cast endtanks were designed in CAD and optimized in CFD simulations. The result is an excellent cooling property with a minimal back pressure. That`s why this kit is perfect for racing use. An optimal cooling effect of the charged air with a significant increase in performance! All WAGNERTUNING radiators are equipped with a heat-conductive anti corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well). Advantages of this product: – significantly better cooling performance – less pressure drop – more power and torque for your engine – mechanical discharge of the turbocharger – 100% pressure resistance – 100% Plug and Play – up to 4 years warranty core dimensions stock intercooler: 276 mm x 136 mm x 76 mm / 10,9Inch x 5,3Inch x 3,0Inch V = 2,85 Liter core dimensions WT intercooler: 287 mm x 185 mm x 115 mm / 11,3Inch x 7,3Inch x 4,5Inch V = 6,10 Liter
