Within a car engine there are many parts that need to be connected with hoses and pipes for the transfer of liquids and gases. In most standard engines, these are made of rubber. This does a job but does have a few drawbacks in terms of appearance and lifespan.
In most cases, replacing your rubber hoses with silicone increases lifespan and makes them easier to clean. It also has some benefits in terms of appearance. With a variety of colours and brands such as SFS available at LK Performance, you can create a consistent design and colour theme for your Ford Focus Mk2 . You might even want to use different colour piping for different purposes: red for coolant and blue for air, for example. It also pays to use the correct fittings when attaching pipes and hoses. Some cheap clip-ons will not last and are prone to leaks.
