3FLANGE 5 OD 6-1/2LONG

The 3FLANGE 5 OD 6-1/2LONG air filter element from K and N Engineering is a precision-engineered intake component designed for automotive enthusiasts and mechanics who prioritize superior engine performance and protection. This three-flange universal air filter adapter serves as a vital connection between your intake system and filtration unit, allowing for customization across various engine configurations.

Manufactured to K and N's high standards, the 3FLANGE 5 OD 6-1/2LONG features a robust 5-inch outer diameter and a length of 6.5 inches, making it compatible with most standard air filter housings and custom intake designs. The three-flange mounting design enhances structural rigidity and provides multiple sealing surfaces, which minimizes vibration transfer and ensures consistent filter retention under varying engine loads.

This adapter is particularly beneficial for fabricators, engine builders, and performance shops working on custom intake manifolds or upgrading OEM filter housings. Its lightweight design of 1.25 pounds contributes to optimizing intake dynamics and reducing parasitic drag, making it suitable for both naturally aspirated and forced-induction systems.
