THE DEFINITION OF THE SPORTS CLEANER
Generally, three qualities in particular are sought in air filters; air intake quantity, filtration efficiency, and durability. As each of these requirements are in conflict with each other, extensive experience and certain technological adeptness are necessary to bring these into a higher balance. For example, while a material for use in the cleaner may have equal filtration efficiency as another, considerable air intake may be possible − in that case high efficiency is retained, but, depending on the suitability of the material, long-term durability cannot necessarily be obtained.
Using the American company SuperFlow's air flow bench, tests were carried out rating and comparing the internal airflow dynamics of the K&N High-Flow filter and the many other air filters currently available. Tests to compare (material size, filter assembly) filter shape, design, and air intake were conducted on the Sports Cleaner.
| Test filter | Air Intake Volume (cubic feet/minute) |
Ratio |
| Sample A (dry-type non-woven fabric) | 438cfm | 48％ |
| Sample B (dry-type sponge) | 623cfm | 69％ |
| Sample C (wet-type sponge) | 517cfm | 57％ |
| K&N PC-0965 (wet-type cotton) | 910cfm | 100％ |
It was K&N's air filter with this unmatched level of performance, a product of joint research and development between GruppeM and K&N Engineering. One case in point which has long been understood well, is that the ideal form for the inlet duct is considered to be a bell-mouthed funnel shape. By having an equalised uniform curve, in the case of nothing being stuck to the surface causing turbulence, great airflow performance is demonstrated. However, should even a little unevenness be on the surface, it would create resistance and cease acting as a funnel, because of the resulting turbulence. The configuration of the K & N High-Flow filter is cone shaped, having uniform tapered proportions. In this way, a funnel-shaped vortex is formed, with natural air being drawn and channelled in toward the airflow of the intake air. When air is sucked with a fixed angle of descent, air from all around the cone is also sucked in simultaneously, a funnel shape of the natural air is formed, and more air is inhaled. This design which at first glance seemingly disregards theory, through the stacking up of results of test upon test considering only of the achieving of high performance, has been brought to fruition – introducing the K&N Power Cleaner Air Filter.
A unique filter design concept based on a uniform tapered angle, and optimisation of the deeply pleated accordion form, devised so to have over 5 times the circumference surface area. Outstanding performance in continuous filtration has been achieved by improving filter capacity, reducing excessive stress caused by suction, as well as safeguarding against distortion caused by extreme heat.
The kit is completely purpose-designed and can be mounted securely, bolted on using the fitting adapter to fit beautifully as an original part would. If the fitting is not correct, there is a likelihood of vibration, and the intended effectiveness would not be obtained. The GruppeM Power Cleaner kit has all the fittings needed so that anyone can carry out installation reliably and effectively.
The K&N High-Flow Filter is reusable with cleaning, so an astoundingly long life can be assured. The filter can be cleaned safely by washing to breakdown any accumulated dirt without damage to the cotton. By washing, drying and applying the oil, the filter can be restored to deliver the equivalent level of performance as the new item. The K&N air filter, not emitting undesired waste, nor exhaust fumes on installation, clears test studies regarding regulations in every country in the world, so that it can be used with peace of mind by even the most environmentally consciousness owner.

FILTER MASK
M's Filter Mask is a specially designed foam filter wrap made to extend the service interval of your K&N air filter when used in very dusty conditions to protect against mud, pebbles, etc., and is effective against cold, having been treated with antifreeze. They are made from large, open cell foam. The Filter Mask will stop 90% of the dirt, yet only add a 2% restriction to the airflow of the filter and can also be cleaned with soap & water.

POWER CLEANER FILTER COVERS (Wrap type : Dry Cover)
K&N Dry Covers are manufactured from a durable polyester material and pre-treated with a proprietary hydrophobic process designed to prevent splashes of water or mud from saturating your K&N air filter. The Dry Cover will also stop small dirt particles ; yet add little restriction to the airflow of filter. Please be aware the Dry Cover is water repellent, not waterproof. Depending on conditions and usage, the water repellent treatment is good for 1 to 2 years.
