PHILTOP Engine & Cabin Air Filter Kit for Ford Fiesta 2011-2019 — CA10997 & CF11670 Direct-Fit, DIY-Friendly

PHILTOP's two-piece filter kit supplies both the engine air filter and the cabin pollen filter precisely matched to Ford Fiesta models from 2011 through 2019.

When you need reliable replacement filters for a Ford Fiesta (2011–2019), this PHILTOP combo kit saves time and removes guesswork. The set includes the engine air filter (replacement for CA10997) and the cabin air filter (replacement for CF11670), packaged together so you can swap both at once and restore performance and interior air cleanliness. Each component is engineered for a direct fit that aligns with original equipment dimensions and installation points.

How does replacing both filters at once benefit my Fiesta?

Changing the engine and cabin filters simultaneously reduces downtime and ensures both systems perform as intended. A fresh engine filter helps maintain airflow and filtration for the intake system, while a new cabin filter improves the air you breathe inside the car. Replacing both on the same schedule prevents one component from limiting the other's effectiveness.

• One kit contains both engine and cabin filters matched to Ford Fiesta 2011–2019.
• Coordinated replacement reduces service frequency and labor time.
• Balanced filtration supports engine efficiency and passenger comfort.

What makes these PHILTOP filters compatible with my vehicle?

PHILTOP designs this kit to match the original part dimensions and mounting requirements for the listed Fiesta years. The cabin filter is specified as a CF11670 equivalent and the engine filter as CA10997 equivalent, ensuring the seal surfaces and filter media align with factory housings. That direct-fit approach simplifies installation and reduces the chance of leaks or poor seating.

• Direct OE-fit form factors tailored for Ford Fiesta 2011–2019.
• Replacement numbers CF11670 (cabin) and CA10997 (engine) for easy cross-reference.
• Precision-cut edges and sealing surfaces to match factory housings.

How easy is installation for a DIYer?

Both filters are intended for fast, tool-light replacement. The cabin filter typically resides behind the glovebox and can be accessed in minutes without specialized tools, while the engine air filter sits in an under-hood housing that opens quickly. Clear instructions are included so owners can complete the swap during routine maintenance.

• Cabin filter accessible behind the glovebox — usually no tools required.
• Engine filter located in a top-mounted housing under the hood for quick access.
• Simple instructions included for straightforward DIY installation.

When should I replace these filters?

PHILTOP recommends changing both the engine and cabin filters every 12 months or 12,000 miles as a practical maintenance interval. Driving conditions such as heavy dust, pollen seasons, or urban pollution can justify more frequent replacement. Sticking to a consistent schedule keeps intake performance steady and cabin air fresh.

• Suggested interval: every 12 months or 12,000 miles.
• Shorten interval when frequently driving in dusty or polluted environments.
• Regular replacement prevents strain on HVAC and engine intake systems.

Who this kit is for: Drivers and DIY owners of Ford Fiesta models from 2011 to 2019 who want a convenient, correctly matched pair of replacement filters in one purchase. It’s aimed at anyone seeking an easy, cost-effective way to maintain intake performance and cabin air quality — from routine home maintenance to quick shop service. The PHILTOP kit removes uncertainty by combining both filters sized to the factory housings, helping you complete the job fast and confidently.
