What You Need to Know Before Buying a Replacement Air Filter

Your Isuzu D-Max’s air filter isn’t the most attractive part of your vehicle, but it plays a crucial role in how your vehicle performs. Its purpose is to ensure your engine gets enough clean air to burn fuel with, so it’s definitely not something you should overlook when performing vehicle maintenance. The air filter protects your engine from getting filled up with dirt, dust, debris, and even glass shards, flying insects and other small particles that can get kicked up from the road and into your Isuzu’s air intakes.

Although they are extremely simple devices, there are many different DMax air filter models to choose from. They vary in the materials they’re made from, and in terms of model design. That being said, you’ll have to pick a filter that fits your engine’s filter. As a result, you’ll be quite limited in your options for a replacement Isuzu DMax air filter. So some of the things to consider when buying a brand new air filter are the following.

First and foremost, you need to ensure a proper fit. This means shopping for a filter that’s made for your specific model, year and make of Isuzu. Check the filter you have already, and buy an identical replacement. Alternatively, you may want to upgrade to a high-flow and washable air filter, but you’ll still have an idea of the shape and size to look for. Of course, you’ll also have to consider the price. Most basic air filters cost 20-30 bucks, and most washable, high-flow filters cost 50-100 bucks.

Personally, I prefer washable air filters, simply because they last longer as long as you take proper care of them, which is not too much of a hassle. You’ll have to wash it once or twice a year, which you can do when performing regular maintenance for your Isuzu.

Then, you’ll have to consider the filter’s surface area. Engine filters have folds or pleats of material that act as a gateway. The reason they’re usually pleated is that the more surface is the air filter can provide – the better, simply because there’s more material to act as a barrier between the internal atmosphere of the engine and the dirty air trying to get into it.

And lastly, some filters boast higher temperature resistance properties than others, so if you’re living in a place where the mercury of your thermometer is constantly going upwards, it might be a good idea to look for a filter that features high-temperature resistance properties.
