6-3/8x2-3/8 Paper Element

The TRANS-DAPT 6-3/8x2-3/8 Paper Element (Model 2116) is a universal replacement air filter designed for custom intake systems and engine modifications. This paper element addresses a critical need in high-performance and street-rod builds where off-the-shelf filters don't fit modified intake manifolds or carburetors. Mechanics and enthusiasts rely on this component to maintain clean air delivery in custom-tuned engines while preserving OEM filtration efficiency.

Constructed with pleated paper media, this filter element traps particulates and contaminants before they reach fuel injection or carburetor systems, directly protecting engine longevity. The 6-3/8 by 2-3/8 inch dimensions make it ideal for tight engine bays where conventional round filters create packaging conflicts. The lightweight design minimizes intake restriction, supporting responsive throttle response and consistent air-fuel mixture delivery in tuned engines.

This filter element works best in custom intake setups, stroker builds, and vintage restorations where filter sizing must match non-standard intake configurations. Installation requires a compatible filter housing (sold separately), and it suits both naturally aspirated and moderately boosted applications. Regular inspection and replacement every 15,000–20,000 miles under normal conditions keeps engine performance predictable and prevents abrasive wear on valves and piston rings.
