14x4 Air Filter Element

The MOROSO 14x4 Air Filter Element (Part Number 97081) is a universal round paper air filter designed to deliver reliable engine breathing across a wide range of automotive and equipment applications. With a 14-inch diameter and 4-inch height, this filter element provides a proven design for intake systems requiring high flow capacity with effective contaminant removal. The white paper construction is engineered for standard filtration duties in vehicles, generators, compressors, and stationary power equipment.

The 14x4 configuration balances substantial filter surface area against compact packaging, allowing adequate airflow for engines that demand efficient volumetric breathing without excessive restriction. Paper media in this size range typically handles moderate to heavy dust loads in non-extreme environments, making it suitable for typical shop, field, and residential duty. The universal fitment means compatibility across multiple engine and intake manifold designs, provided your system uses a round canister-style filter housing. Proper element replacement intervals—typically when visible dust accumulation occurs or per manufacturer guidelines—maintain optimal air-to-fuel ratios and engine performance.

Users maintaining shop compressors, portable generators, stationary engines, and older or custom-built automotive systems rely on universal filter elements when OEM-specific replacements are unavailable or cost-prohibitive. The MOROSO brand positioning in the performance and industrial segment underscores durability and fit reliability. This element is a straightforward consumable replacement—stock it as a backup for critical equipment to avoid downtime during maintenance cycles.

When sourcing replacement air filters, verify your housing bore diameter and element height against this product's 14-inch round footprint and 4-inch depth to ensure proper seal and fit. Quality paper media resists moisture absorption and maintains integrity across seasonal temperature swings typical of shop and outdoor equipment service.
