Loren’s Auto Repair: Why Replace Your Engine Air Filter?

Just as our bodies need clean air to function properly, your Subaru engine needs clean air to operate efficiently. Let’s go egghead for a minute. For every gallon of gas we burn driving on MT interstates, twenty pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce twenty pounds of carbon dioxide?

The answer is that the carbon comes from the gasoline, but the oxygen comes from the air. You see, it takes about twelve thousand gallons of air to burn a gallon of gas in your engine. Clearly, your Subaru needs a lot of air to keep going in Whitefish. A lot of clean air is best.

Loren's Auto Repair: Why Replace Your Engine Air Filter?You’ve seen the pictures of people in Japan wearing face masks. They want some kind of filter to keep unwanted pollution and germs out of their lungs. Well, your Subaru also works better when its internals are clean. When your Subaru air filter’s dirty, it simply can’t trap any more dirt, so the pollutants just pass through into your air intake system. From there it can clog your fuel injectors and even get into the motor itself. Not surprisingly, burning dust and pollen in your Subaru engine does you no good.

So, we’re talking potential damage for Kalispell drivers. But another big thing is wasted fuel. Your Subaru engine management computer tries to mix the correct amount of air in with the fuel. If the filter’s clogged, there isn’t enough air for the optimal fuel to air mix and that really messes with gas mileage.

In fact, replacing a dirty air filter at Loren’s Auto Repair in Kalispell can improve your fuel economy by up to ten percent. At today’s Whitefish fuel prices, you should be able to pay for a new air filter before your next oil change.

The verdict: When your Subaru engine air filter needs to be replaced; it needs to be replaced. How often depends entirely on the level of air pollution where you drive in MT. A simple visual inspection at Loren’s Auto Repair will tell you when you need a new engine air filter.

When you look at the air filter on your furnace at home and see it’s all clogged up with dust and dirt, you don’t hesitate to replace it. When your Loren’s Auto Repair service advisor shows you your nasty engine air filter, you now know why you should go ahead and replace it.

Excellent service!! We are from Wisconsin and found Loren's on the web. They were able to fly in a new front axle and get us on the road in just 3 days at a very reasonable price. A quick follow up visit for adjustments allowed us to continue our vacation as planned. Absolutely recommend them. Mark was personable and knowledgeable, they offered a shuttle service and John was a great technician for our Xterra!!

This was the best car repair shop I have ever done business with. For being a young woman, who honestly doesn’t know a ton about cars, they were very thorough in explaining things and I trusted that they weren’t trying to rip me off based off my lack of knowledge or me being a young girl. Too many times have mechanics/car maintenance men try and rip me off. Once someone tried to charge me $180 for an oil change! Ridiculous. But not with these guys. They were awesome. My car broke down at a horrible time when I was busy with work and about to go on vacation. I had my car towed there and didn’t have time to stop by. They inspected it very soon after that, and got ahold of me. Then I was out of town for a couple weeks and they let me keep my car there. Even when I got back they had put it in the shop the night before so all the snow would melt. They were very friendly and even have a complimentary shuttle service when needed. I wish I could give the names of all the people who helped! Chad was awesome and answered all my questions and my dads when he called from a state away haha! The young girl who picked me up from the shuttle was super nice and has good people skills. If I ever have car problems again they will definitely be who I go to. Thanks guys!

Lorens never disappoints! They continually meet above my expectations. They met competitive rates, they have been upfront with charges and even gave me a loaner vehicle while doing their repairs. I will only ever use this shop. Mark at service desk is amazing and very knowledgeable!

I'm out here in West Glacier on vacation. During the trip, we hit a pothole and the exhaust started making a loud noise. We figured a hole had rusted open or something similar. We called Loren's Auto Repair to get it checked out, and they were awesome with recommendations. They let us explain the issue and then confirmed what we thought it was. They weren't able to get us in before we left, but they were kind enough to suggest a mechanic in town that possibly could squeeze us in. This conversation was a sign of trust and good business. The prices they quoted were fair and had excellent customer service. Thanks!
