The ALTA Performance dual stage foam drop in panel filter provides maximum power gains while still removing harmful particles from your intake air charge.
Paper and gauze filters only trap dirt on the surface of the filter. As the filter gets dirty the surface will begin to restrict the air flow to your motor. The ALTA Performance foam filter will trap dirt in the air charge on many different levels of the 3 dimensional foam matrix. As the filter gets dirty it will not restrict air flow.
The ALTA MINI Performance panel filter has a large surface area and is produced in a vivid blue to visibly show the user when the filter needs to be cleaned. Easy to clean and re-oil for years of use.

n.b. These do not fit cars manufactured from July 04 onwards, a new style for these will be available shortly.
