If you think your BMW 325i Performance lacks something, you are not alone. The performance in the BMW 325i is run by a 2.5 6 cylinder engine. Don't get me wrong it is definitely a powerful engine that performs well, but after driving it a while you may get a little bored. Don't worry you don't have to sell your 325i and get an M3 if you don't want. The 6 cylinder in the 325i still has a lot of room to have the performance increased. To start you will need to add one of the following:

  • 325i Air Intake System
  • 325i Performance Exhaust System
  • Performance Software Chip
  • 325i Performance Suspension

By adding any of these products to the 325i will either horsepower or handling, both of which you will need if you are planning on racing or just simply to improve everyday driving. The software chip will increase air and fuel within the car, which may end up giving you worse gas mileage, not to much less though however. The best way to get the most power out of the vehicle is to upgrade the air intake and the exhaust at the same time as adding the performance chip to the 325i. That way the software chip will tell the air intake system exactly how much air to pull in to mix with the fuel, meanwhile you will have a great performance exhaust system to let all this increased air flow out of the vehicle, by adding all these parts at the same time you should increase the cars total horsepower by about 35-75 horsepower which is definitely a very noticeable gain. With the increase in power you will need a performance suspension system for the 325i to keep the tires stuck to the road beneath it. After this the car will be noticeably faster, next you can modify the exterior styling of the machine.325i performance is a must.
