The apr k04 turbocharger system is a drop in turbo upgrade that dramatically increases power. Everything depends on the exact construction. Even a well-made 4-cylinder motor can rival v8s by combining them with a turbocharger, improved exhaust system, and using advanced fuel injection strategies.The K04 turbocharger is a great turbocharger for the Gen 2 TSI engine. It delivers 330-350 horsepower which is a good, reliable amount on the stock engine.We have provided the K04-023 turbocharger with a upgrade, so you can drive with our turbocharger up to 330 HP. So that this also holds at higher loads, the turbo is equipped with a reinforced support. Original 023 turbochargers can be loaded up to a maximum of 260 HP, after that the wear is increased significantly.The turbocharger is what makes an I4 engine truly stand out. It works by forcing exhaust back into the cylinders, which creates bigger explosions as the pistons pump air into the cylinders. The result is more power and higher horsepower in larger engines that can outrun comparable V6 engines.
