Frequently Asked Questions (FAQs)
1. How do I know which engine air filter I need?
To determine the correct engine air filter size, you can open the air filter housing, remove the filter, and take it to an auto parts counter for reference. Alternatively, you can check your owner's manual for the part number or search online.
2. Do engine air filters make a difference?
Yes, regularly changing your car's air filter has several benefits. It extends the engine's lifespan, reduces emissions, improves fuel economy, and can even enhance performance depending on the type of filter used.
3. How often should engine air filter be changed?
It is recommended to change the engine air filter at least once a year or every 12,000-15,000 miles, depending on which comes first. If you frequently drive in dusty or dirty conditions, you may need to replace the filter more often. Some filters have a service life indicator that changes color when replacement is needed.
4. What are the three types of air filters for small engines?
Briggs & Stratton engines utilize three types of air filters: paper, foam, and dual element. These filters, along with a filter cartridge and pre-cleaner, ensure smooth operation of small engines.
5. How can I tell what size air filter I need?
If your HVAC system has an air filter, you can find its size by checking the existing filter. Most filters have the dimensions (length, width, and depth) listed on the side in inches, typically in that order.
6. Does engine air filter increase horsepower?
Yes, a high flow air filter can increase horsepower by approximately 3 to 5 HP, as well as improve torque, by allowing more air to reach the engine.
7. Do better air filters restrict airflow?
While high-efficiency air filters may have higher MERV ratings, they can sometimes impede airflow, resulting in reduced HVAC system efficiency, higher energy bills, and potential furnace damage from overheating.
8. What are the symptoms of a dirty engine air filter?
Some symptoms of a dirty engine air filter include a dirty filter, unusual noises, check engine light, black smoke or unburned fuel smell from the exhaust, lower fuel economy, and hesitation or stumbling during acceleration.
9. What are the symptoms of a bad air filter?
Signs of a bad air filter include strange engine noises, decreased performance, reduced fuel economy, black smoke or flames in the exhaust, smell of petrol in the exhaust, a visibly dirty filter, and the check engine light coming on.
10. Does air filter shape matter?
Yes, the shape of the air filter can impact the amount of air intake and, consequently, performance. The two most common shapes are panel and cone.
