PHILTOP CA12933+CF12935 Engine & Cabin Air Filter Set

PHILTOP CA12933+CF12935 is a matched engine and cabin air filter kit engineered to replace the factory filters in Jeep Grand Cherokee L (2021–2025) and Jeep Grand Cherokee (2022–2025) for improved engine protection and cleaner cabin air.

This two-piece kit bundles the PHILTOP engine air filter (CA12933) and cabin air filter (CF12935) so you can replace both at the recommended interval without hunting for separate parts. Each filter is manufactured to fit the specified Grand Cherokee model years and is intended to restore airflow, trap contaminants, and keep the engine and interior ventilation operating as designed. The set is designed for direct OE-style fitment and simple DIY installation for drivers who want a convenient, cost-effective maintenance solution.

How do these filters protect my engine and performance?

The engine air filter (CA12933) captures dust, road debris, and particulates before they reach the intake system, helping maintain combustion efficiency and protecting internal components. Replacing the engine filter on schedule preserves airflow and can prevent premature wear on sensors and moving parts.

• High-efficiency media traps common road dust and larger particles.
• OE-form dimensions for correct sealing and airflow paths.
• Reduces engine contamination that can affect performance and longevity.

What does the cabin filter do for in-car air quality?

The PHILTOP cabin air filter (CF12935) filters pollen, dust, and airborne particles from the incoming ventilation air, improving comfort for occupants and reducing particles that circulate through the HVAC system. It also helps limit odors and visible dust on interior surfaces when replaced regularly.

• Designed to capture fine dust, pollen, and common allergens.
• Fits behind the glovebox for quick, tool-free replacement in most cases.
• Maintains HVAC efficiency and fresher-smelling cabin air.

How easy is it to install these PHILTOP filters myself?

Both filters are engineered for a direct OE-style fit, so installation is straightforward for most owners. The cabin filter typically swaps out from behind the glovebox with minimal effort; the engine air filter is accessible under the hood and changes in a few basic steps. PHILTOP includes clear instructions to guide a smooth DIY replacement.

• Direct-fit parts that match OEM shape and mounting points.
• Cabin filter usually removed without tools; engine filter accessible by standard clips or housing screws.
• Step-by-step guidance reduces installation time and guesswork.

When should I replace both filters and why replace them together?

PHILTOP recommends replacing both the cabin and engine air filters together every 12 months or 12,000 miles as a simple, synchronized maintenance interval. Doing both at the same time streamlines service, ensures balanced protection for the engine and occupants, and prevents one dirty filter from undermining the benefits of the other.

• Recommended interval: 12 months or 12,000 miles.
• Simultaneous replacement saves time and avoids staggered maintenance tasks.
• Balanced filtration supports both engine performance and cabin comfort.
