JR AirFilters were founded in 1992 and in the ten years since has grown
to be one of the largest suppliers of performance air filters in the world.
McNamaras hold an extensive selection of both panel and induction JR AirFilters
in stock. Please contact us via email or telephone with any queries you may
have.
JR Airfilters are manufactured with 4 layers of chirurgical cotton, which
are held together by 2 layers of steel wire mesh. To prevent rust, they are
galvanized and covered with plastic which gives increased corrosion
prevention. At the factory the filter is impregnated with a special oil.
This oil is an very important element of the filter.
Due to the
construction, the material and the oil, the dust which is in the air, is
retained outside of the filter and serves as a supplementary filter element.
This is the reason the service interval, before the filter needs cleaning is
about 100,000 miles (160,000 Km)! JR Filters produce a filter for (almost)
every car and also supply a large selection of induction kits
No more filter change is necessary. 40% more air is passed through a JR
filter compared to a standard filter currently in your car. A JR filter's
filtration capacity is more than 97.5%. The most stringent car manufacturers
demand only a filtration of 96%. JR Filters come with a lifetime guarantee
against parts degredation of the filters. They are washable, that means they
are always reuseable. The other benefits of fitting the filter are an
increase in performance and economy.
Tests in the UK with heavy duty trucks
proved that all trucks equipped whit those kind of filter, had between 7.5
and 8% less consumption. These filters can be used for cars, trucks, lorries,
buses, aeroplanes, vessels, motor saws, lawn mowers, industrial and farm
tractors and any other application where Clean Air is necessary. JR Direct Induction Kits 
On many cars the air filter system is often
iverly sophisticated and the air must go round corners and long pipes before
it enters the engine. This creates turbulence which disturbs the air flow
and reduces the power of the engine. To eliminate this loss of power JR
Filters created the JR DIRECT KIT’s which are available for many cars. In
most cases the existing air filter system is partly or completely removed
and replaced by a filter which has an intake area of 360°. All parts
required to fit the system come supplied in the filter kit. Some of those
Kit’s have TüV homologation. Fitting the induction kit enables the engine
to breathe better giving a corresponding power increase of between 8 to 15
Bhp depending on the size of the engine. The sound of the engine also
changes giving a more sport engine note.
