AIR FILTERS

Bronze Medal

As you would expect, the paper element finished third It captured around 120 grams of dirt over an 11 minute run before the filter became clogged and registered the pressure differential drop on a manometer of 6 inches of water. The starting reading was 17.84 inches of water, and the ending differential was 23.84 inches of water.

Silver Medal

The RamAir (similar to Pipercross) multi-stage foam filter finished first in dirt holding holding capacity. It captured a massive 199.81 grams of dirt but with a larger starting and ending pressure differential. This means the foam filter works well out the box but less well with a layer of dirt.

Gold Medal

The cotton gauze filter (BMC air filters K&N and Green all use cotton gauze) finished second in terms of filter effciency with it capturing 140.08 grams of dirt over a 22.8 minute run before the filter clogged up and registered the pressure differential change of 6 inches of water. HOWEVER the start pressure drop was just 16.8 inches of water making this the best all round filter material. The starting differential pressure was 16.80 inches of water and the ending pressure differential was 22.80 inches of water.

Balance Motorsport can offer the superb range of BMC Filters including the Carbon Dynamic Airbox. This device ensures a supply of cold air to the filter and using a venturi effect and front air intake actually increases the velocity and volume of air being drawn into the engine. If the airbox is not listed for your vehicle we can either custom design and install a setup for you or if you are too far away you can order a range of pipes and clamps that should enable you to install a CDA on any vehicle. We still offer cone filters from BMC but remember with these to focus on getting a good cold air feed. In addition have a look at our Heat Management products. If you can reduce underbonnet temperatures then you can probably increase power.
