G’day John,

Finally after getting my information correctly to you, I was able to install the second Hiclone.  It took less than 5 minutes to install and was as easy as falling off a log, even for me with bugger all mechanical experience. I am really pleased with the performance of the Hiclones and would recommend them to anyone, they are absolutely brilliant.

Subject: Fuel economy using Hiclone

Hi John

Just to let you know that the fuel consumption on my 2007 bf falcon wagon 6cyl improved from 10.2lt per 100km without Hiclone to 8.1lt per 100km with 3 Hiclones. Highway driving. Excellent

Thanks Graham W

Hi John,

This is the first testimonial I have ever given on a product, mainly because the advertised claims usually fall short of reality. However after 5 months of use in my dual fuel UZJ100R 4.7 litre Landcruiser I would have to say that the fuel saving on gas and petrol is around 15-20%. The engine at 400 000ks has never sounded sweeter.

Kind regards David M

80 Series:- Hiclone:- On my 94 model Landcruiser. I've got more range and easier cold starts. I do a lot of big bush runs and fuel economy is the main thing – my 4wd with it's snorkel had a range of 905Km on 145Lt – now that range 1,280 on a tank. 41% improvement. Now that’s where I’m impressed.

Try our fuel combustion Calculator it will tell you what your average fuel usage is, you need to this know this before you can move forward, once you have it you will then have something to aim for.

K&N air filters allow up to 50% more air flow than the standard paper filters, the better your engine can breathe the better it performs and gives you greater fuel economy, coupled with the Hiclones vortex effect that wants to and does suck more air in they work very well together and you’ll never buy another filter, as they are washable and give you a 1.000.000 Mile warranty.

Why use K&N Air Filters

K&N Air Filter

K&N replacement air filter are designed to improve vehicle performance, provide excellent engine protection and last the life of your car. K&N air filters in most cases are very easy to install.

  • Save fuel and gain power
    • An engines power output is decided by how much air it can draw into the combustion process. More air means more power means better fuel efficiency.
  • Save Money
    • Being re-washable the air filter is a one-off purchase, how many air filters would you have to buy in 1,600,000km.
  • Save the Environment
    • For each K&N filter there are fewer air filters at the tip.

      Why are we selling K&N filters:

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

      Jeep Cherokee 2004:

      Needless to say I wont be asking for a refund as the combination of Hiclone and the K & N air filter gave me a power gain 19kw on the dyno. David C.

      How does a K&N air filter work:

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

      Hiclone and K&N Filters:

      Whilst a Hiclone will create 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 devices complement each other. One provides more air the other provides the means to move it.

      How do I wash the filter

      1. Pre-clean by brushing and tapping 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 spray on Air Filter Oil

      How often should I wash 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 filter and wash at this interval. e.g. if you replace every 10,000km then you would wash at every 40,000km. On a street driven vehicle a filter can last up to 80,000km before a service is required.

      Hiclone is a very simple device that is installed into the air pipe between the air filter and the engine. The Hiclone has a series of fins, as the air is being sucked or forced through these fins it make the air spin, the device doesn't move, it makes the air move. No matter what fuel, Petrol or LPG, the fuel needs air for the fuel to ignite.


      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.

      Hiclone: In most vehicles up to 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 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.
      Placing a Hiclone into the inlet manifold or the hose just before it, will give you 5-15% increase in power & between 10-20% better fuel economy, installing a 2nd unit at the air filter end will give you 30-50% more than one unit.

      Hiclones are made from laser cut, high pressure spot welded stainless steel, they're handmade with "no moving parts" so its maintenance free, just fit and forget. The Hiclone is easy to install and can be fitted to a large range of vehicles, including; trucks, cars and 4 wheel drives and Motor bikes.

      Hiclone has a 98% success rate so we're not complaining about the 2% that return, no one cant get 100% of anything so that's why a 120 day (4 months) unconditional money back guarantee is given, all we want is for you to give it a fair go, if your not happy with the results give me a call and sent them back. You've nothing to lose and a lot to gain just by giving them a go.
