found this apparently the itg filter reduces noise not makes it louder
which i can concur is true, certainly doesnt make it louder than the standard paper filter.
"itg were probably the first company to manufacture a truly durable, high performance foam-based production air filter.
Why foam? Because, compared to paper or other filter technologies, reticulated polyester foam achieves 'optimum performance' against three key criteria:
Maximum Air Flow - the ability to allow air to pass through without causing a large drop in pressure.
Cleaning Efficiency - the capability to arrest a high proportion of airborne dust while feeding the engine clean air.
Dust Load-up Tolerance - the capability to absorb a large amount of dust without reducing air flow capacity.
The unique Tri-Foam System, which uses various thicknesses of finer or coarser foams, these factors can be varied for different applications.
Tri-foam gives flexibility to produce air filters to exact specifications and, where high flow rates are possible, we can tailor filters to arrest even the slightest dust traces.
Compared to other designs, itg filters offer many additional advantages, including a significant reduction in noise while providing more power for longer.
What's more, because itg use the very latest adhesive technologies to bond the foam layers, itg filter assemblies are totally resistant to water, fumes, oils and fuels - including the exotic brews used in racing."
