NOTE: Synthamax Air Filters do not require oil. Service air filter as needed by cleaning with common non-petroleum allpurpose household cleaner and water. Simple Green®, Formula 409® or equivalent works great. Apply cleaner to outside of air filter and allow to soak. Then flush filter clean from the inside out with a garden hose and repeat steps if necessary. Do not apply high pressure water or air to clean filter. Allow filter to air dry and reinstall.

Resonator Delete Option: The resonator can be safely deleted if so desired by capping off the Intake Tube with the supplied Cap and Speed clamp. After removing the resonator assembly from the firewall, insert the included Firewall plug to prevent debris from entering the cabin.
