Product Details

This air filter housing is used to enclose the engine air filter and help maintain the intake path between the air inlet and the engine. For 2005-2007 Ford Focus models, including applications listed without PZEV evaporative emissions, the SKP SK258519 provides a fitment-specific replacement option. It is a practical choice when the original housing is cracked, warped, or no longer seals properly.

The SK258519 is also referenced by interchange numbers 4S4Z9600BA, 735-7810, 258519, and FO3990100, which can help confirm application matching during parts lookup.

Common Reasons for Replacement

• Broken or cracked air filter housing
• Improper sealing at the air intake assembly
• Contamination entering the filter area
• Damaged housing from prior service or impact

Installation Notes

Verify the vehicle’s emissions configuration before ordering, since this part does not apply to PZEV evaporative emissions models. Confirm the housing shape, mounting points, and intake connections against the original unit before installation.

Quality Assurance

SKP replacement parts are cataloged for application-specific fitment, and the SK258519 is identified by OE-style cross-reference data for the listed Ford Focus coverage.
