In modern automobiles, the air must be filtered before it enters the engine cylinders to prevent abrasive particles from causing mechanical damage. The engine air filter takes care of this task. Without air filters, engines will be strained and damaged by foreign particles.
But air filters, just like everything else, can't withstand harsh environmental conditions. Eventually, they need to be replaced to keep your car in peak condition. Poor gas mileage and ineffective emissions control system are some of the symptoms of worn air filters. If you want to buy a new filter, there are some things to remember so that you will not regret your purchase.
Which type of air filter is best for my car?
There are different types of air filters to help improve your car's performance. Listed below are the different types that you can choose from if you're looking for a new air filter.
- Paper: Because they are cost-efficient and effective, paper filters are commonly used in factory automobile assemblies. They are made from industrial-grade paper and folded like an accordion to trap dust and debris. Though paper filters are cheap, they need to be replaced often to avoid engine problems.
- Foam: Made from polyurethane foam soaked in oil, foam filters are frequently used by off-road drivers because of their excellent filtering capacity. Although foam filters are thick and reusable, they disintegrate over time and clog engines.
- Cotton: Oil-wetted cotton gauze is used in high-performance filters for race cars because it increases an engine's air intake. But because cotton filters are considered high-performance upgrades, they are expensive.
Which brand of air filter should I buy?
Because air filters are important engine components, many car parts manufacturers produce filters. In fact, because there are too many brands, air filters can range from $20 to $399. But, price is proportional to quality, so choose a brand known for its high quality and affordability.
Which is better: OEM or aftermarket air filter?
If you want to buy a new air filter, you can choose between original equipment manufacturer (OEM) or aftermarket air filters. OEM filters are usually more expensive, while aftermarket ones come with a number of brands and options. But just because OEM filters are expensive doesn't mean they are better than aftermarket filters. If you want factory-like performance, choose OEM filters. But if you want customizable performance, choose aftermarket ones.
