- Gasket - provides exterior seal between the filter and engine at the engine mounting surface.
- Mounting Plate - prevents deflection (movement) at the gasket sealing surface. Heavy gage steel plate provides for threaded attachment to the engine
- Inner Element Support - provides inner element stabilization and a positive seal between the inner element and the mounting plate to prevent the bypass of unfiltered oil.
- Upper End Cap - retains element end sealant and filter media, provides an outlet for clean oil, and provides structural rigidity to the pleated media.
- Lower End Cap - retains element end sealant and filter media.
- Arch-pleated, Prescription-blended Filter Media - provides a more than adequate filter area. The element has a controlled porosity blended media to assure complete filtration of the oil.
- Spiral-wound Center Tube - provides internal element support. The spiral design greatly reduces initial flow restriction when compared to other designs.
- Coiled Spring - ensures a constant load on the inner element to maintain the seal between the upper element end cap, the inner element support, and the mounting plate even during pressure surge situations.
- Filter Canister - encloses the assembly with a mechanically-locked double seam. The canister provides "flutes" at the closed end for ease of removal with an oil filter wrench.
- Silicone Anti-Drainback Valve - Flexible in extreme temperatures, improves oil flow and keeps oil in filter to prevent engine destroying dry starts. Provides lasting protection meeting newer vehicle longer recommended oil change schedules.
- By-pass Valve Assembly -- Spring loaded valve assembly allows oil to by-pass the element under high-differential pressure conditions such as cold oil and/or excessively contaminated media. Allows lubrication of the engine, but without full-flow filtration
