Filters

While a high-quality air filter, like an oiled performance filter, can improve airflow compared to a very dirty standard filter, it won’t drastically increase horsepower on its own. It mainly helps the engine breathe more to slightly improve performance. Unfortunately, expecting a huge horsepower jump from just a filter change is unrealistic.

“Lifetime” or reusable filters, like those made from oiled cotton gauze, can be a good investment if you plan to keep your car for a long time. They reduce waste and can save money in the long run. However, they need to be regularly cleaned and re-oiled. If you neglect their maintenance, they can perform worse than a standard disposable filter. So, they are only worth it if the owner is willing to do the maintenance.

While a magnetic oil drain plug can capture some larger metallic particles, it does not replace your oil filter’s function. The oil filter removes very fine particles and contaminants that a magnetic plug won’t catch. Additionally, the filter removes other contaminants like dirt, soot, and sludge, which the plug does not. The magnetic plug is a supplemental measure to help reduce wear, but your oil filter remains the primary defense against engine damage from contaminated oil.
