Subaru Impreza Engine Parts

  • Actuators


  • Dump Valves

    Dump Valves

    A Subaru Impreza dump valve will help to prevent compression surge, helping to prolong the life of your turbo. They can also give you a boost in performance by improving response. Even after you lift your foot off the accelerator, air continues to flow into the turbo from the compressor. With access to the engine now blocked, the air has nowhere to go except back through the compressor again. This causes a fluttering sound as the air is forced back over the compressor’s blades. This will not only sound unusual, but the increased air pressure can result in increased wear and tear. Installing a Subaru Impreza blow off valve will give this air an alternative escape route. This prevents a build-up of pressure in the turbo while also preventing it from being forced back through the turbo compressor. This removes that unusual sound and also helps to keep your turbo in great condition for longer.
  • Induction Kits

    Induction Kits (15)

    A Subaru Impreza induction kit is one of the first performance upgrades that many people use. The job of an air filter is to prevent particles from getting into the engine and causing damage. They also help to muffle engine sounds. The filter is usually held in an airbox, but this airbox will tend to restrict the flow of air into the engine. The airbox will also usually sit on top of the engine and this means the engine will be fed hot air. A Subaru Impreza induction kit is a type of engine filter that is usually cone-shaped and fitted to the end of a tube that feeds directly into the engine. These filters are not held in a box, meaning the air-flow is not restricted and the filters can be placed where they have access to relatively cool air. This means your engine is fed with more oxygen, giving more power, while also giving you that characteristic induction roar.
  • Intercoolers


    A Subaru Impreza intercooler can help to give your engine an impressive boost in performance. A turbocharger’s job is to force additional oxygen-rich air into the engine, thus increasing the rate of combustion. When this air is forced through the turbo, however, it becomes very hot. Air becomes less dense when it is hot, effectively meaning that less oxygen fuel is available. This causes the turbo to become less effective than it otherwise would be. A Subaru Impreza intercooler is basically a type of radiator that cools the air before it reaches the engine. This increases the density of available oxygen, providing more for your engine to work with. This will boost the rate at which your engine combusts fuel, giving it a significant boost in horsepower. In addition to more power, an intercooler will also provide added reliability as the temperature of the air reaching the engine remains more consistent.
  • Radiators


    A Subaru Impreza radiator will help to keep your engine as cool as possible, helping it to run smoothly. It is an upgrade that you should consider if you are upgrading other aspects of your engine. With so many moving parts in action, your car’s engine can get very hot. Thus, cars are fitted with a radiator to help keep the engine cool. Car engine radiators work by having a coolant running through pipes in canals in the engine. This allows heat to be transferred to the coolant, which is then carried away from the engine to the radiator at the front. Here, the coolant is cooled again before travelling back to the engine. If you are upgrading other components of your engine to produce more power, this is likely to mean an engine that produces more heat. This can mean you need an upgraded Subaru Impreza radiator to help keep the engine cool enough.
