Motor Saver Traxxas 2.5 Air Filter

Introduction

The stock T-Maxx air filter is a dramatic improvement over previous versions. However, as always in the Maxx world, there's an upgrade for it. One of the most highly regarded aftermarket filters available is the Motor Saver. The Motor Saver filters share some characteristics with the stock air filter, however in some design areas you can see some dramatic differences.

The basic Motor Saver kit provides you the parts shown to the right. You'll get the filter assembly itself,with a pre-oiled filter, and two wire ties. Before I go any further, let me stress the importance of the ties. To provide a proper seal, and to prevent any filter from slipping off the carburetor, you should use wire ties. Otherwise there's not really a purpose to running a filter at all, because dirt could enter the engine and destroy it.

One of the nicer things about the Motor Saver filter is the ease at which the filter element can be changed. You simply push the front of the assembly in slightly, and then twist it. It then it pulls right out allowing you to swap the dirty filter element for a new one. If you elect to swap elements in the field, I would recommend lightly spraying some compressed air on the exposed filter screen before removing the old element. This will help ensure dirt and debris doesn't find it's way into your motor when reinserting a clean filter element.

If you are running under heavy dust conditions, you might want to also consider using the Motor Saver filter along with their black outer off-road filter. This filter slides over the Motor Saver Assembly and helps filter the air before it even reached the inner filter. This helps to provide ultimate protection in extremely dusty environments. It also helps keep the mesh filter housing cleaner, so that you shouldn't encounter any dirt when swapping elements in the field.

The kit containing the outer element also comes with a spare inner foam. Both are shown in the picture to the right.

Looking at the air filter, one can easily see that it greatly increases the surface area over the stock filter. In extremely dusty conditions the stock filter can easily become clogged. This leads many people to replace the stock filter with more inadequate means of filtration, so that they avoid the filter clogging up. In time, a filter such as that, can cause premature engine wear. However, with the increased surface area of the Motor Saver filter, you have a much larger area for the air to enter the filter and you still retain the foam filtration method which is preferred for a nitro's ring-less piston.
