An internal combustion engine uses oxygen just as fires require oxygen to keep aflame. There is no internal oxygen tank in a car for this purpose, as that wouldn’t be very efficient. Instead, Subaru B9 vehicle manufacturers equip cars with intakes that bring air inside to the Subaru B9 engine directly. Subaru B9 Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Subaru B9 car all the way to the engine, though stock versions aren’t always the most effective.
For that reason, many car owners turn to aftermarket Subaru B9 air intakes to increase the effectiveness and efficiency of their vehicles’ intake capacity. The greater the amount of oxygen supplied to the engine, the more power it can produce. Subaru B9 Cold air has more oxygen, for instance, so Subaru B9 cold air intakes have become popular Subaru B9 intake upgrades. Other upgrade types focus more on greater Subaru B9 air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Subaru B9 air intake system in your car.

The lowering height is perfect on my car.
I have the full H&R set up on my car and I love the quality of the parts. I have sold my Eibach springs to get the H&R coilover and I know my decision is right! Thanks Ilovebodykits
