In my years in the automotive industry, I’ve learned that Subaru owners love their cars with good reason (the Subaru commercials are not lying!). Subaru’s handle well, have powerful engines, and with a few exceptions seem to last “forever.” Most Subaru’s sold in the US for from 1996 until now have been based around the 4 cylinder, 2.5L EJ25 engine in some variation.
There are many parts of the car which can be replaced to make your car run stronger and faster. This is true no matter what the manufacturer. Simply pulling one part and dropping in another will alter the amount of power or gain which is achieved by the engine. Many people looking to enhance the performance of their vehicle will run into a wall unless they take the time to update the software which is being used by their car. This means altering the engine computer software which is being used to regulate the many different functions the vehicle performs.
As surely as our joints grow sore with age, so too, do our vehicles become more noisy as they grow older. It’s part of the automotive aging process. Unfortunately, tracking down the source of the squeaks and vibrations is often more difficult than mere part failures. If your catalytic converter or alternator fails, you’ll know within minutes. If your transmission or engine overheats, the smoke billowing from under the hood is a clear sign.
