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, Scion XD vehicle manufacturers equip cars with intakes that bring air inside to the Scion XD engine directly. Scion XD Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Scion XD 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 Scion XD 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. Scion XD Cold air has more oxygen, for instance, so Scion XD cold air intakes have become popular Scion XD intake upgrades. Other upgrade types focus more on greater Scion XD air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Scion XD air intake system in your car.

This straight pipe is very nice. I bought 1 myself for me 85 Corolla and it sounds really nice also. I don't use the silencer as much but besides that everythings nice. I'm 15 right now and I'm trying to get somewhere with my 85 Corolla that me dad loaned to me. They straight pipe I bought just killed it. Its really awesome!
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
