Fram Extra Guard Engine Air Filter for Subaru CA9997 — Fits H4/H6 engines, 12,000‑mile life

FRAM CA9997 Extra Guard Engine Air Filter is a replacement air filter engineered to block road dust and debris while helping maintain engine performance for up to 12 months or 12,000 miles.

This FRAM Extra Guard CA9997 is built with advanced filter media to trap more contaminants than many standard retail filters, aiming to keep the intake air cleaner and the engine running smoothly. It is precision-shaped to fit specific Subaru engines and models, making installation straightforward and maintenance predictable. The filter's design balances airflow with particle removal so your vehicle can breathe while its internal components stay better protected from abrasive particulates.

How does the CA9997 improve everyday engine performance?

Replacing a clogged air filter with a fresh FRAM Extra Guard can restore airflow to factory-like levels, which supports consistent throttle response and steady operation under normal driving conditions. The media helps limit the amount of dirt entering the intake, which helps protect sensors and combustion quality.

• Helps maintain airflow for stable acceleration and power delivery.
• Reduces strain on intake sensors and fuel/air mixing.
• Designed for everyday driving scenarios and routine vehicle use.

Will this filter fit my Subaru model and engine?

The CA9997 is manufactured to match specific Subaru airbox dimensions and seal points for a proper fit. It lists broad compatibility across many Subaru Outback, Forester, Legacy, Impreza, WRX/WRX STI, XV Crosstrek, and Tribeca model years and engine sizes—always double-check fitment for your exact year and engine size before purchase.

• Compatible with multiple Subaru H4 2.0L, 2.5L, H6 3.0L, and H6 3.6L engines.
• Fits model ranges including Outback, Forester, Legacy, Impreza, WRX, WRX STI, Crosstrek, Tribeca.
• Verify year and engine code against the product listing or vehicle manual.

How long does the FRAM Extra Guard air filter last and when should I replace it?

FRAM recommends replacing this Extra Guard filter at intervals up to 12 months or 12,000 miles under normal driving conditions. If you frequently drive in dusty, off-road, or heavy-traffic urban environments, inspect the filter more often and replace it sooner if you notice visible contamination or reduced engine responsiveness.

• Typical recommended maximum interval: 12 months or 12,000 miles.
• Shorten replacement intervals for dusty or severe driving conditions.
• Visual inspection helps determine contamination level before scheduled service.

What are the practical benefits of choosing the Extra Guard media?

The advanced media in the CA9997 captures and retains more dirt than many basic retail filters while still allowing sufficient airflow for reliable operation. That balance helps protect engine components from abrasive particles and supports steady daily driving performance without complex installation steps.

• Captured contaminants are held within the media to reduce engine exposure.
• Precision fit reduces bypass risk and simplifies the swap-out process.
• Designed to support routine maintenance cycles with minimal fuss.

Who is this for: The FRAM CA9997 Extra Guard is designed for Subaru owners looking for a straightforward, reliable replacement filter that matches factory fitment and emphasizes contaminant control. It suits drivers who perform regular maintenance, those who seek to restore throttle response after a dirty filter, and anyone who wants a durable, OEM-compatible air filter for common Subaru models across multiple model years.

Features summary:

• Helps maintain engine airflow and consistent power delivery.
• Advanced media captures and holds dirt and airborne debris.
• Precision fit for easy installation in compatible Subaru airboxes.
• Recommended replacement up to 12 months / 12,000 miles under normal conditions.
