Hiclone is a simple non-moving and maintenance-free device made of stainless steel, which fits inside the air filter housing of a carburetor or in the air induction hose on EFI, turbo, LPG or diesel engines. This creates a swirling cyclone or tornado like effect to the airflow into the intake manifold and combustion chamber of any engine.

Hiclone has No moving parts and will therefore out last the life expectancy of any engine.

They do, and have done so for years.

The new (2004) Mercedes V6 fitted with Hiclone style swirl technology has 18% more power than the previous engine. The economy has also improved from 12L/100km to under 10L/100km, a 2L/100km or 17% fuel saving (figures from Govt. tests printed in “Car” and “Wheels” magazines).

Before this Subaru got 10% more economy and more power from their new (2000) WRX by fitting valves in their inlet runners to create a greater swirling of the intake charge in the combustion chamber (“Wheels” magazine).

Why does the same part work on one car and not work on another same model car? The reason is normally related to Air/Fuel ratio or engine tune. Hiclone increase's airflow at all times by up to 21%. The only time Hiclone can’t work is when there is a mechanical, electrical or fuel system problem. This means the engine is un-able to match the air/fuel ratio to the increase in airflow generated by the Hiclone product. If you add a lot of products to a car to increase airflow through the inlet or exhaust, at some point you will need to add more fuel to match (eg: in the UK if you fit a sports air filter to SU carbs you need to use richer needles). But this can be fixed. This is also why the first Hiclone usually saves more fuel than the second; it has access to the most un-burnt fuel. It is also why we offer the 30-day money back guarantee, so you have the choice to either have the problem fixed and save more money, or get your money back.

The rule is that any engine is only as efficient as the amount of fuel it can completely burn per combustion stroke and convert into power (torque), the more air per combustion stroke, with the correct air/fuel ratio, the bigger the bang and the right foot spends less time on the pedal.

These engines generally have the highest fuel wastage, due to the distance the fuel has to travel prior to combustion. The Hiclone carries the fuel in the centre of the airflow, away from the sides of the manifold, to the combustion chamber.

We claim 15-20% fuel savings, but some old cars have achieved figures higher than 35% fuel savings.

By increasing the swirl in the combustion chamber, to over three times the swirl the engine can ever naturally generate, Hiclone reduces the smoke from incomplete combustion by 50%.

Fuel savings on a new engine will be 5-10%, and on an older engine 10-20%. It is also common for customers to install extra Hiclones to non-turbo vehicles as well. On our "Economy” page there is the “4X4 Australia” magazine test on a 4.2L Toyota diesel. They achieved 17% with one and 23.5% fuel savings with two Hiclones fitted.

By using sensors like Air Flow Meters on the inlet and O2 sensor on the exhaust, the engine's ECU will match the air/fuel ratio and create a new fuel map. The ECU will need time to re-learn (about a week) this is why dyno shops who test products by doing one run without, and one run with any product don't know how to use a dyno on an EFI car (as proven in the “Street Commodore” magazine test on our “Power” page). You will use less fuel to achieve and maintaine the same speed. A second Hiclone will give a further increase in airflow.

Turbo Engines

For Turbo vehicles we suggest installing Hiclones in two locations.

The first Hiclone is installed near the intake manifold; after the Turbo or intercooler; to improve combustion and economy.

The second part is installed near the air filter, before the Turbo. This part helps the Turbo Impellor to spin, reducing Turbo lag, bringing the boost in around 400-500rpm earlier.

It is also possible to install extra Hiclones in power or economy positions to further improve the vehicle. We have a lot of customers with up to 6 Hiclones installed on one vehicle.

Hiclone is the most effective gas mixer available and large gains have been achieved with Hiclone on these engines. Some people argue that gas and air mix naturally because they are both gases, but this is the same as saying that oil and water mix well because they are both liquids. We claim fuel savings of 5-10% for vehicles optimised for gas only. And up to 20% fuel savings for vehicles converted to gas (Dual Fuel). Gas mixture must always be checked after installation.
