• Directional Tyre

  A directional tyre is designed to better channel water and snow away from under the tyre. They are generally used in high-performance applications. Because of their arrow-like tread design they only work in one direction, and can only be rotated front to back.

• Intake Manifold

  The intake manifold is a series of tubes that distribute air and fuel to the cylinder head from the carburettor or fuel injector. If you have a leak in your intake manifold, the air/fuel mix can become lopsided and the internal combustion operates less efficiently. A poor idle or sluggish acceleration is an indicator of a leaky intake manifold.

• Lock Cylinders

  Lock cylinders are part of the locking system of your car. The lock cylinder is where the key fits. You will have to replace the lock if the lock cylinder is damaged.
