Why High-Quality Engine Air Filters Are More Important Than Ever
When we talk about the importance of any automotive filter, it’s usually in the context of the physical protection that the filter provides, whether it be for the occupants of the vehicle or the engine. And make no mistake, the level of physical engine protection that the air filter provides is very important as the primary function of the filter, but it’s not all that matters anymore. The engine air filter of any vehicle powered by an internal combustion engine is a relatively small, seemingly insignificant part, that has a massive impact on modern engine performance. In fact, the engine air filter found in the air intake system of modern vehicles is more important than it’s ever been.
Engine Air Filter Impact on Performance
Sometime around the early to mid 1980s high-end automakers began using computers in the cars they manufactured. The so called “computers” used were really just small electronic control units designed to communicate with a variety of sensors positioned throughout the car. By 1995 almost all cars rolling off of every assembly line were equipped with some form of electronic control unit and a multitude of sensors which provided feedback for them to act on. Fast-forward a quarter century and we find that vehicle electronics and engine management have become significantly more complex. The ECUs of the mid-90s have evolved to function on levels comparable to a conventional personal computer. The names and acronyms they’re called by might vary from one automaker to the next, but they all manage the same types of distributed systems – braking control, chassis control, body control, safety, powertrain control, and engine control.
