What is the best way to clean my GM Performance Parts Dryflow air filter?
Dryflow air filters can be cleaned by removing the air filter from the vehicle and gently swishing it in a bucket filled with a diluted solution of water and mild dish soap. Measure the length of the filter element and fill the bucket with the soap and water solution to match the filter element length. For example, if the filter is 9″ long, then fill the bucket 9″ with the solution. This is important because solution with contaminant can enter the filter opening and be deposited on the inside of the filter. Rotate the filter element back and forth to agitate the dirt off the filter. The filter should then be rinsed with clean water. This process may need to be repeated two to three times. Shake the filter to remove as much water as possible. Before reinstalling the filter, make sure the element is dry or only very slightly damp. Excess water on the element may cause damage to the MAF sensor.
