Airflow Snorkel Kits

 

 

Airflow SnorkelA brief history of Snorkels

Snorkels have been in use for a long time on vehicles and craft. Before World War 1, they were used on tanks and later on submarines. After WW1 and the mechanization of agriculture, they were fitted on tractors and transport vehicles with the unique purpose to supply the engine with air free of water and contaminants. In more recent times, with the advent of leisure 4WD vehicles, snorkels are now mostly fitted to allow the crossing of rivers without causing damage to the engine. However, more benefits can be obtained from a well designed Snorkel. This is where the Airflow Cold Air Induction System (ACAIS) comes to the rescue.

ACAIS is much more than a fancy acronym! The ACAIS is designed to improve the fuel efficiency and power of your vehicle. These two goals may appear contradictory, but we have succeeded in combining them. In the process, we did not forget style; fitting like a glove, the Snorkel complements your vehicle. Once installed, your 4WD will be ready for new adventures and maybe some river crossings! Not all snorkel body designs in the big wide world produce a cold air induction effect. This effect improves fuel efficiency while improving also engine power. Airflow has been conducting airflow studies, friction loss assessments and performance testing in its laboratories for many years to achieve this effect.

A combustion engine needs air and fuel to operate. The more air and oxygen flow into the intake manifold, the more efficient is the combustion. The ACAIS harvests fresh air at roof level where it is the least disturbed. This air contains less contaminant and is cooler than air absorbed from the engine bay. When the air is cooler, it contains more oxygen. Modern vehicles are fitted with engine management systems; these are computers which measure accurately in real-time all inputs available to the engine to improve its efficiency. Consequently, the availability of cooler air inflow results in more power and torque. Three main parts constitute an ACAIS: a 'hat' we call the 'Air Ram', a Snorkel tube we call the 'Body' and a performance air filter (not included). Contact us for more information about high performance filter options for your vehcle. The three parts are designed to complement each other in their efficiency.

 

Airflow Snorkel kits for 4x4 and 4WD vehicles...

The Air Ram
Air entering the Air Ram swirls violently, creating a cyclonic effect. The heaviest particles are ejected by the centrifugal force to the periphery of the swirl. There, they hit the vertical ribs where air pressure takes over to eject them out of the four slots at the base of the Air Ram. At this point, the air pressure pushes them out. The finer particles that are not ejected are removed by the vehicle air filter.

The Body
Now that the air is free of large particles, it starts travelling down the snorkel body in a straight line. The body may be of two types, induction or non-induction. In the induction case, the air slows down because it enters in a larger volume, the plenum chamber. The swirling created by the Air Ram diminishes, thus reducing friction losses. There, the air is buffered, immediately available for the air box at positive pressure. The engine management system can use it readily.

The Performance Filter
This is a replacement for the air filter which is not included in the Airflow snorkel kit. Contact Rocky Road for options regarding performance filter systems.

 

Airflow Snorkel kits can be seen below. Click on the price bar to view the excellent low Airflow prices. All kits are for Left Hand or Right Hand drive unless otherwise specified.

If you see your vehicle listed with a different engine type (but same vehicle), please email us for details as often these snorkels can be adapted to work with any size engine as long as the vehicle is the same. We do not have pictures of all vehicles and kits at this time, but you can scroll down the webpage to view some installed applications for those vehicles we do have pictures files of...

 

We also carry the Safari Snorkel line. If you don't see an Airflow Snorkel for your vehicle, check our Safari product line for additional snorkel kits
