afcchartsWhy use K&N air filters?

  • Save Fuel by Gaining Power
    • An engines power output is decided by how much air it can draw into the combustion process. More Air means More Power and Greater Fuel Efficiency.
  • Save Money
    • Being washable the air filter is a one-off purchase, consider how many air filters would you have to buy in 1,000,000 miles.
  • Save the Environment
    • For each K&N filter bought there are far fewer air filters at the tip.

Why are we selling K&N filters?

Our customers tell us of their experiences of using the K&N filters in Australian conditions. After talking performance and fuel economy day in/day out with people all over Australia, you get to hear what is a great product.

Jeep Cherokee 2004: Needless to say I won't be asking for a refund as the combination of the Hiclone and K&N air filter gave me a power gain of 19kw on the Dyno and much better fuel economy. Many thanks. David C.

How does a K&N filter work?

K&N Filters use a pleated, oiled cotton fabric element. Paper elements depend upon microscopic holes to filter, as these become clogged the filter efficiency drops. Dirt particles collected on the surface of a K&N filter element have very little effect on air flow because there are no small holes to clog. Particles are stopped by crisscrossed oiled cotton fibers and held in suspension by the oil. This results in a 30% or more better air flow rate than paper filters whilst maintaining filtration efficiency, also being pleated, it has a bigger surface area than that of a flat foam filter.

Hiclone and K&N filters?


Whilst a Hiclone creates a vortex to present an ordered, denser airflow, one of the limiting factors is air filter restriction. Basically, you can't get more air into the engine if the air filter is holding you back. These two fuel saving products complement each other. The K&N filter allows more air, the Hiclone provides the means to move it.

How do I wash the filter?

  1. Pre-clean by brushing and tapping the loose dirt off
  2. Soak for 10 minutes in the K&N cleaning solution
  3. Rinse under tap and dry completely
  4. Re-oil with K&N air filter oil

How often should I clean the filter?

As with any air filter this depends on the conditions you are driving in. As a rule of thumb, quadruple the kilometers in which you would replace a standard paper filter and clean at this interval. e.g. if you normally replace every 10,000km then you should clean at 40,000km. On a street driven vehicle a K&N air filter can last up to 80,000km before a service is required.
