Air filter replacement is essential to help protect your car's engine. Engines that work by internal combustion need lots of clean air so that the fuel can burn and provide the force which powers the engine.

Engines must have very clean air for this task because if dirt, dust or particles get inside the engine it will cause damage. That's why a clean air filter is important. It filters the air before it goes into the combustion chambers and protects parts like the pistons and cylinders from wear and damage. Over time the filter can become clogged and this reduces the amount of air being supplied to the engine.

Save money on petrol:
It's imperative that your engine has a very precise mix of fuel and air, so if your air filter is clogged and the engine gets starved of air then your vehicle will ‘run rich' which puts strain on your engine, and can increase your fuel consumption by up to 10%and no-one wants to use more petrol than they have to!

Protect your engine:
Old air filters get clogged and weak and become more likely to get damaged, allowing all kinds of particles into your system - these particles can cause very expensive damage to your vehicle.

So while changing your air filter might seem like something you can put off to save money - the benefits a clean air filter gives you in petrol savings, improved performance and engine protection will leave far more money in your pocket in the long run.
