K&N 57 Series FIPK
* 50-State legal
* Up to 15% more power
K&N’s Fuel Injection Performance Kits, (FIPK’s), replace your power-robbing factory air box with an open element, 360-degree conical filter. A special sheet-metal baffle (when needed) isolates hot underhood air from being sucked in by your engine. It is connected to a smooth-flowing, heat-resistant composite intake tube that rejects heat and attaches to your engine’s intake system. The result: smooth laminar airflow and a cooler, denser charge of air for maximum power and efficiency.
K&N 63 Series Intake Systems
* Street Legal in most states (not street legal in California)
* Up to 15% more power
The same advanced technology that goes into K&N’s FIPK Intakes goes into its Airchargers. In fact, many Airchargers are 57 Series FIPKs that are just awaiting CARB certification. Emissions-legal in most states, K&N’s Airchargers are an excellent way to add more performance to your Truck or SUV.
K&N 77 Series Intake Systems
* Polished aluminum intake tube
For those who want the performance of K&N’s FIPKs with a show-style polished aluminum intake tube, K&N offers its 77 Series Intake Systems. Designed to replace your restirctive factory filter and airbox, the 77 Series intake features a mandrel-bent aluminum tube for smooth, unrestricted airflow. A black powder coated steel heat shield isolates the 360-degree K&N conical filter from underhood heat. Additional K&N standard features include reinforced silicone attaching hose and stainless steel barrel clamps.
