Audi S4 Radiator

The Audi S4 Radiator is the frontline defense of the car against heat and it is fast to draw energy out of the turbocharged engine, keeping the horsepower unchanged and the parts intact. The cores are made of lightweight aluminum bonded to tough plastic tanks, which is a formula developed over the years of Audi performance sedans to provide the Radiator with remarkable resistance to corrosion and keep the nose weight low enough to provide a sharper steering response. The same compact heat exchanger can fit with ease whether it is installed in the original B5 S4, the well-known B8, or the new B9 because the mounting positions and hose position are the same and therefore it is easy and fast to upgrade or replace. The coolant can be found rushing in dense fins within its system of slim tubes, and incoming air through the grille or the electric fan removes the heat before the liquid recirculates, and the V6 can remain in the sweet spot during rush hour idling or during spirited climbs of the canyons. The Radiator also increases the efficiency and safety of every Audi driver as steady temperature implies the presence of denser intake air and consistent oil pressure, which, in turn, promotes more powerful acceleration and steady braking electronics. Valved pressure seals prevent leakage at crimp seams and internal baffles evenly redistribute flow, minor features that make this component unique in a market full of competitors. Despite the fact that the needles on the gauge are stuck halfway after numerous laps at the track, owners report that the Radiator continues to perform its duties without drama. Combine the unit with new G13 coolant and an opaque front grille and the high-revving Audi will remain cooler under pressure, which translates into more turbo life and fewer unwanted sudden stops. It is especially the S4 cooling package, based on this highly responsive part, that drivers have complimented as being overbuilt for daily commuting but prepared in case of weekend autocross, a credit to the larger Audi philosophy of integrating luxury and durability.
