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

good coilover kit for my IS, significantly improved the handling on cornering and not too stiff for daily use. highly recommended.

Pretty good quality finish, great fit, weave is okay, and it's the only option out there that I know of which explains the high price (-1 star).
