This K&N 57-2542 FIPK is supplying hot air to the engine, which is less-efficient than the factory filter box & tubes. A K&N filter also requires occasional service with special soap & oil. The hood cowl seal is degraded and not fully attached. The cheap AGM battery is OK, but does not hold a full charge (~695 of a specified 750CCA). The terminals are clean & tight, and the positive cable has been replaced recently. The jack handle is missing. The brake fluid is black, indicating that it has not been changed on-schedule. The SCDS recall has not been performed. The aftermarket plugs, wires, cap, & rotor appear to be recent, but the cap & rotor do not have the recommended dielectric grease and the wires are too long to be routed properly. The overflow/windshield tank's left mounting tab is broken, but a hook has been added to support it. The whole engine bay & undercarriage should be washed.
