afcchartsWhy we recommend & 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 better 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 air 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. Many thanks David C.

How does a K&N air filter work

K&N Filters use a pleated, oiled cotton fabric element. Paper elements depend upon microscopic holes to filter the air, 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 better 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 devices complement each other. The K&N filter provides more air, the Hiclone provides the means to move it.

How do I wash the air 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 drive 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.



Fuel Prices helped, reduce car petrol costs.

Petrol prices up, Diesel prices up, economy down. Hiclone fuel saver will improve your fuel economy and reduce your vehicle fuel costs. Your litres per 100KM can be helped. Petrol, diesel Tdi & LPG or your money back.

Hiclone: In most vehicles 1x, 2x or 3x Hiclones will work very well for you and 4x units if you have a snorkel, we  give you a 120 day (4 months) money back guarantee, we suggest you put them all in at the same time and see how they go over the next 30-50 days, then, if you want to, take the one out at the filter end and if you think you don't need it give me a call and send it back, basically 1's good 2's better 3's best and 4's is the ultimate.

Installing Hiclone near the throttle body will give you 5-15% increase in power and between 10-20% better fuel economy, a second unit at the filter end will give you 30-50% more than one Hiclone.
Diesel / Tdi:
Installing Hiclone just before the inlet manifold will give you between 5-15% increase in power & 10-20% better fuel economy, if you have 100mm or more between the inlet and inter-cooler you can place a 2nd just after the inter-cooler this will give you up to 50% more than one unit, installing one at the filter end of the induction pipe (pre-turbo), will assist the turbo and bring it on up to 600 RPM earlier, this also eases the load on the engine which helps your fuel economy.

This is how Hiclone works. By spinning the air you get an improved mixture between the air and fuel, this gives you a better combustion, hence more power and fuel economy.

You've nothing to lose and a lot to gain just by giving them a go.
