The three layers of foam selected for ITG filter combined with the dust retaining oil, provide an extremely high level of filtration to protect the engine from all the damaging particles in the ambient air stream.

ITG filter performance is unaffected by very large quantities of dirt arrested in the filter. Long after other makes have blocked up and reduced the engine power, ITG filters will still flow air with exceptionally low pressure loss.

ITG is the choice of Audi Sport North America for use in their Speed TV GT Series S4.

ITG air filters are reusable and need periodic cleaning. Please see this document on proper cleaning instructions. Air filter spray oil is available above.
