CAI Upgrade for Your Classic Pickup.
Awaken the slumbering beast in your 1997-2003 F-150’s engine with the K&N Series 77 High Flow Performance Cold Air Intake, a component that energizes the whole system easily and effectively by greatly increasing cold air inflow. Vehicle engines are, in effect, air pumps, and this CAI supplies enough cool, oxygenated air to put +9.7 horsepower and +12.44 ft-lbs of torque at your command. Even more importantly, it gets everything running more strongly and smoothly, conserving gasoline, boosting throttle response, and making better driving performance at all RPMs.
No Tune Required.
The K&N Series 77 High Flow Performance Cold Air Intake works as intended with the stock tune still in place on your F-150 engine. No aftermarket tune is required to operate this part correctly.
Excellent Reusable Oiled Filter.
The K&N Series 77 High Flow Performance Cold Air Intake has a very large filter element at 9” tall, which is made from oiled cotton gauze. Aluminum mesh is used to strengthen this fabric, and has epoxy covering it. This makes a durable long-time filter that can stand up to heavy use for years. Washable and reusable, it doesn't need its first washing until around 100K miles.
Built for the Long Haul.
The eye-catching aluminum tube of the K&N Series 77 High Flow Performance Cold Air Intake is highly polished for aesthetic reasons, but the choice of metal also makes this component rust-proof. The air box is built out of steel finished in black powder-coat. An EPDM foam “weatherstrip” style seal fits around the outside of this box to create a tighter barrier against engine heat. The component is made in the USA and includes 9 stainless steel clamps.
Fits the OE MAF.
The OEM mass airflow (MAF) moves directly over to the K&N Series 77 High Flow Performance Cold Air Intake, which features an appropriately sized MAF housing. Attachments for necessary vent hoses are also included.
