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

I am riding this spring with my stock shocks and it feels just right. The spring is not stiff like my previous spring set. Thanks Ilovebodykits
