WRX performance parts are a great way to bring your Subaru alive. From the factory the stock Subaru  air filter leaves somthing to be desired, but if you don't have the extra cash to purchase an performacne air filter, please make sure your stock filter is clean. The more air that gets to the engine, the more power you have.

Use premium gas. With gas prices being what they are at present, I know that this is a hard-to-swallow tip at this time. Gas is not cheap, and premium gas can never be purchased at a price that makes it a deal, but you are driving a Subaru WRX, afterall. So, spring for the good stuff! Your Subaru  deserves nothing less than the best.

The next few wrx performance parts are a little more involved however, we are dealing with the Subaru WRX. Extra time and effort results in improved driving performance so it is well worth it.

  The Subaru intake system offers room for improvement. Luckily, there are several possible upgrades that can be done on your own with little mechanical ability, and a few that may require a quick trip to your local speed shop. I have found that these upgrades are an awesome way to increase the performanceof your WRX and ultimately increase power.

Firstly, I should mention that the more involved you become with modifications on any vehicle, the likelier the need may be to upgrade the ECU or brain of the engine. anothor wrx peroformance tip is a few minor bolt-ons such as a cold air ram intake system or a cat back exhaust upgrade may not produce the exact results some are seeking, such as a noticeable increase in power to warrant a ECU check-up, but when you begin experimenting with new turbos, intercoolers, boost controllers and such, you may find an ECU upgrade is in order. That being said, let the intake upgrades begin!

Installing a new after-market air filter is one of the most basic intake upgrades that can be made on the Subaru WRX. peformance parts allow the most air possible to flow through the stock intake system.  

  For the serious enthusiast, some good perofrmance tips are increasing horsepower significantly will require more than just making a simple air filter upgrade. It will be necessary to install a cold air intake system. Installing a cold air intake system on your Subaru allows more air to be taken in by the engine. The benefit here is that the air that is flowing into the engine is cooler and more dense than the air that is being produced by the stock intake system. Additionally, there is some more room for fuel and air in the cylinder when you increase the density of the intake air. This can result in a more powerful engine stroke. Consequently, this modification will cause your Subaru WRX to experience an increase in power.
