Universal Replacement Dry Air Intake Filter by Injen®. Injen/Amsoil EA Air Filter represents a major breakthrough in filtration technology. The revolutionary nanofiber technology used in Injen/Amsoil EA Filters captures more dirt and allows better air flow than conventional air filters with cotton gauze. This filter is a dry filter, it is easily cleaned with shop vac and does not require oiling after cleaning. Tuned and tested for specific application, this filter will not require replacing the factory sensor. You will get longer service intervals and more horsepower compared to custom air intakes with cotton gauze. They improve engine performance and help engines last longer. Testing shows that EA Air Filters hold 15 times more contaminants than a wet gauze type filter.

Note: This is the dry replacement alternative to the filter that came with your SP1899 intake.
