Outer Saver pre-filters have the same high quality, fine micron opening as our new line of Large 1/8 Scale Off-Road air filters.
Outer Savers maintain high airflow longer than oiled 2-stage foam air cleaners alone. Outer Saver pre-filters do not restrict airflow.
Secures tightly around existing filters helping foam and internal plastic parts to stay in place.
Designed to be blown clean with compressed air or lightly rinsed with soap and water.
