If Your Engine Fails, You're Going Nowhere!

Posted by David on

Your engine deserves a great deal of respect and care. Quite simply, if your engine fails, you're going...well, nowhere. You could suffer financially due to the fact that engine repairs are often complex and time consuming, resulting in huge labor costs.

There are two very unassuming, yet relatively inexpensive auto parts that work to protect your engine. These parts, however, accumulate dirt and debris as part of their normal operation and thus require occasional replacement.

We're talking about the modest defenders of your engine’s internal workings - air filters and oil filters. But how exactly do air and oil filters fit in to the operation of your car's engine?

As part of the combustion process, your engine requires air, and takes in a large quantity of it while in operation. On average, your vehicle ingests 10,000 gallons of air for every gallon of fuel it consumes. With that figure in mind, it can be deduced that the volume of air that enters your engine is 10,000 times the volume of gasoline. And as far as this air intake is concerned, your engine does not discriminate, and anything else that may be suspended in the air – bugs, sap, leaves, grime and other debris are fair game. If you live in a particulary dusty environment, the chances of decreased efficiency and performance due to airborne contaminants rises sharply. Under normal operating conditions, it is critical to change the engine’s air filter at least as often as the manufacturer recommends. However, If you do drive in particularly dusty or off-road conditions, it’s a good idea to change the air filter more frequently. This debris will attempt to make its way into the engine bay as part of the normal air flow. Water can get in there, too. If the debris makes it past the air intake and into the engine itself, it can cause abrasion or corrosion - two things you definitely don't want.


An air filter acts as a gatekeeper between the outside air and the combustion chamber. The filter’s job is to act as a catch all, and stop the foreign matter, long before it can get to the engine. What happens when the air filter gets dirty? If you let it go too long, airflow to the engine will be restricted, and starve the engine of air. Why does that matter? Well, as earlier mentioned, air is a chief component in the combustion process – Intake (air and fuel), compression, ignition (power) and exhaust. Without the proper ratio of air:fuel, the combustion process will be inefficient and/or incomplete.

Theoretically, an air filter could get so dirty that the engine wouldn't run. But what's more likely is that a dirty air filter will deprive the engine of just enough air to severely hamper performance. It goes without saying that both scenarios are undesirable.

The typical oil filter, performs a crucially important job – a critical function for a part that is usually the size of a coffee mug. The filter is housed by a metal enclosure with a sealing gasket that allows it to be tightly held against the engine’s mating surface. The base plate of the filter holds the gasket and is perforated with holes around the area just inside the gasket. A central hole is threaded to mate with the oil filter assembly on the engine block. Inside the housing is packed with filter media, most frequently, a synthetic fiber. The engine’s oil pump pushes the oil directly to the filter, where it enters from the holes in the perimeter of the base plate. The dirty oil is pushed under pressure through the filter media and back through the central hole, where it re-enters the engine.


Just as your kidneys clean your blood, an oil filter scrubs engine oil of impurities. Specks of dirt and metal shavings become miniature sandblasters that attack your engine as they float, suspended in engine oil. Their abrasive properties wear down engine bearings, leading to low oil pressure, which in turn, could lead to big-time engine damage. Over time, an oil filter can get so clogged with impurities, that it no longer effectively cleans the oil. In fact, if the oil can no longer flow through the filter media, a bypass valve will open, essentially allowing dirty oil to recirculate, bypassing the filter media, and all protective properties diminish.

There are certain items on your car that you can procrastinate on replacing – your worn out floor mats or that pine treet air freshener, but because of how important air and oil filters are to your engine's health and well-being, these are two replaceable parts you'll definitely want to service on schedule.

Consider it very inexpensive preventive care for your car. As a bonus, your ride will also run better, and best of all, we have everything you need to take care of this today!

We Suggest:

Simota Premium Air Filters

Upgrade your air filter with a high quality rechargeable Simota filter for improved air flow and performance.

Simota was established in 1991 as a manufacturer, specializing in the production of air filters. Over the years, the company invested heavily in research and development to strengthen the quality and advantages of their products. By maintaining strict quality control, Simota earned certification and was issued an ISO9001 certificate by TUV in 2005.

Simota puts their products through rigorous testing, utilizing MAHA LPS3000 dynamometer standards to guarantee that all of their products have been tested to provide the best performance possible. Simota filters are washable and reusable. The non-woven element material allows the filters to be used both dry and wet, which helps facilitate the cleaning process, makes the filter reusable, saving you both time, and money.

Performance improvements vary based on vehicle, but averages at least 5% in MAHA LPS3000 dynamometer testing. Each Simota filter features a light weight design, EPDM frame, stainless steel mesh, deep air inducting corrugation with 200x200 mesh structure, one piece extrusion formed construction and excellent heat durability.

BMW Original Equipment Oil Filter

Keep your high performance engine running cleaner and longer, by changing your oil between regular service intervals. This Genuine BMW - MINI OEM Oil Filter lets you get the job done right.

BMW's recommended Oil Change intervals are between 12,000 to 15,000 miles (20,000 - 25,000 KMs). Even with the high quality synthetic oil that BMW uses, this is a long time to go without fresh oil. You may have the same opinion that many BMW motorists share - that extra oil changes between service intervals is just good practice. Why not save some cash and make it a DIY project using genuine OEM parts.

As an incentive, if you purchase 3 or more filters, we'll throw in a FREE magnetic oil plug to sweeten the deal.

Motive Topside Oil Changer

If you are the do-it-yourself type, make oil changes easier with the Motive Topside Oil Changer. Motive Products introduces a new, innovative topside oil changer called the Power Extractor. The Power Extractor can be used to evacuate engine oil, transmission fluid, brake fluid and other vehicle fluids and features:

An ergonomic locking pump handle with hose holder

A super strong plastic canister

Pressure gauge

Capacity gauge

Lifting handle

2 piece, hose with pinch clip

Lightweight assembly

Mechunik Magnetic Oil Plug

Protect your engine from harmful metal contaminants by installing this magnetic oil plug at your next oil change.

Our special drain plug is equipped with a powerful magnet at the tip that attracts and collects metal particles that may be suspended in your oil. What's more, you can get this Magnetic Oil Plug FREE with the purchase of three BMW OEM oil filters. As a new engine works itself in, it produces metal particles that get collected in your oil pan. These particles can be as small as a grain of sand, or as large as a splinter. As your oil pump pulls oil from the pan, it reintroduces these particles into the car's engine components, seals and filters.

With the Mechunik Magnetic Oil Drain Plug you can gather most of these harmful particles and easily remove them from your engine by simply pulling out the plug and cleaning off the magnet holding the particles. Do this with every oil change for the best results.
