Fitting ITG airfilter
We fit ITG airfilter to BMW E30 M3.
Our choice was ITG JC60/80. Filter BHP rating is up to 450bhp. Overall legnth is 215mm and filter diam. 180mm. This gives 5 extra bhp to BMW E30 M3. If fitting Motec, Hestec or Haltech engine management system it would give 30 bhp (Tested for exaple in Total BMW)! You can see Halteck engine management fitting to Maxtuned BMW E30 M3 and Ford Sierra Cosworth 4x4 later.
The best air filter successfully balances the following:
1. Maximum Air Flow - the filters ability to allow air to pass through without causing a large pressure-drop.
2. Cleaning Efficiency - the capacity of a filter to arrest a high proportion of the dust carried in the air, whilst feeding the engine clean air.
3. Dust Load-up Tolerance - the capability to absorb a large amount of dust, without reducing air flow capacity.
ITG Introducing
ITGs are one of the best air filters ever made. ITG's current range is the product of 13 years of constantly striving for the best designs, made from the best materials with the best manufacturing methods. The best proving ground for any performance product has always been motorsport, top teams from WRC/F2 Rally Cars to Super Touring and Formula 1, make ITG their first choice in air filtration.
The technology of 'Reticulated Polyester Foam' allows greater flexibility in design and performance than paper or other filter technologies. This gives the opportunity to make an air filter to your exact specification. ITG were perhaps the first to make a truly durable and high performance foam based production air filter. This heritage has stood in good stead throughout the competition world for nearly a generation.
By using various thicknesses of finer or coarser foams, ITG designers can vary the above factors to achieve the optimum for each application. It has been shown that small quantities of dust particles smaller than 10 microns have no significant effect on engine wear, so the materials used in our range of filters have been carefully selected to give good air flow capacity, excellent load-up tolerance, and high efficiency whilst avoiding unnecessary extraction. Where high dust flow rates are possible, we tailor the filters to arrest even the slightest dust.
In addition, ITG filter construction reduces noise significantly, when compared with competing designs. Although any competition-type filter will lead to an increase in noise over original equipment, an ITG filter will probably give more power for longer, whilst remaining quieter than other competition filter types.
ITG filter materials have benefited from new technology in the way we bond the selected layers of foam to each other. The adhesives used in filter assembly have to be resistant to water, fumes, oils and fuels (including exotic brews for racing).
