When to Replace Your Engine Air Filter
Knowing when to change your engine air filter helps your car keep its power and efficiency. Using the Spearhead air filter taught me the best time to make the change.
Signs You Need a New Air Filter
If your engine feels sluggish or gas mileage drops, the filter may be clogged. My car hesitated during acceleration after several months.
A dirty air filter can also make the engine sound louder or rougher. When I checked mine, the paper element was covered with dust and particles.
This meant it was time for a replacement.
Recommended Replacement Schedule
Most experts suggest changing the air filter every 12,000 to 15,000 miles. This matched my experience with the Spearhead filter—it kept performance steady in this range.
If you drive in dusty areas or heavy traffic, change the filter sooner. Your car will run smoother and keep good fuel efficiency.
| Condition | When to Replace |
|---|---|
| Normal driving conditions | Every 12,000 – 15,000 miles |
| Dusty or harsh environments | Every 6,000 – 10,000 miles |
| Noticeable engine performance drop | Immediately |
Replacing the air filter on time keeps your car running well. The Spearhead filter fit nicely and made replacement quick.
