K&N Drop-In Replacement Air Filter (04-08 5.4L)

More Power. Unleash the hidden power of your F150 or SuperDuty's 5.4L engine by replacing your restrictive OEM paper filter with a free-flowing K&N Drop-In Replacement Air Filter.

Protect Your Engine. K&N's legendary layered design uses oil-treated cotton gauze between two epoxy-coated aluminum wire screens. The oil creates small pores through which air flows more freely compared to OE paper filters. Unlike paper, the tackiness of the oil collects and filters out the dirt and contaminants that could otherwise harm your engine. It's the best of both worlds - high airflow and superior protection, in one affordable package.

Save Money. Unlike paper filters, which have to be replaced at regular intervals when they become clogged with dirt and contaminants, K&N's filters can be cleaned and re-charged with their filter cleaning kit. In addition to making more power, you'll even save some green.

Direct Replacement. K&N's replacement air filters install in the factory location for an easy, hassle-free installation. No cutting or trimming is required.

Application. This K&N replacement air filter fits 04-08 F150s or 05-07 F250 or F350 SuperDuty with the 5.4L engine.
