“Automotive air filters are overrated.” That makes as much sense as the airplane mechanic who says, “Wings are overrated.” Without those wings, that plane isn’t going to get off the ground. Unfortunately, you can drive without an air filter on your car, or with a very dirty air filter on your car. Either situation is not preferable.
The air filter filters the air that mixes with gasoline as it enters the engine cylinders. Adding particles of dust or debris reduce the efficiency of the air-fuel mixture when it burns. In that way, a dirty mix of air and fuel is inefficient and reduces the performance of the engine.
Additionally, when the fuel burns dirty, as is the case with a dirty mix of air and fuel, it leaves additional residue in the cylinder and the exhaust system, from the exhaust valves on out. That residue can add wear to the cylinder walls and clog the catalytic converter quicker. A catalytic converter is not an inexpensive piece of equipment. Extending its life is one way to reduce the maintenance costs of your vehicle.
Another problem, when the air filter is full of dirt is that it restricts the flow of air, too. This affects the proportions of the air-fuel mix going into the engine. Your car is designed to operate with an optimal mix of air and fuel. When it runs rich, as is the case when there is a higher proportion of fuel to air, it burns dirtier. Once again, this is bad for the cylinders and the exhaust system. It will also foul the spark plugs sooner.
The air filter is a relatively inexpensive part. But, as we have seen, it plays an important role in the operation of your car’s engine. How often should you replace your air filter? Your car’s owner’s manual will give you a rough idea. However, it also depends on where you drive.
If you go through construction zones often, some of the dust kicked up by the road work will find its way into your air filter. In the process, the air filter will clog faster.
The other way to tell if you need a new air filter is to do a visual inspection. You hold the filter up to the light and, depending on how much light gets through, you can determine if it’s time to replace the filter. Here, experience is helpful. A qualified auto repair technician will generally inspect your car’s air filter at no cost. Assuming you can trust them not to try selling you an air filter you don’t need, they’ll let you know how your air filter is doing.
At Performance Unlimited, they pride themselves on only installing parts that are needed. And, right now, they’re offering a Winter Special on air filters (through April 30). If you have an air filter installed, along with an oil change, you’ll receive $10 off for a ProSelect NAPA filter and $20 off for a NAPA Gold Air Filter.

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...
