Air Filter Swap

While the stock filter provides plenty of airflow to the motor, the front face can get clogged with dust quickly when running offroad. So many people prefer to use a filter such as the Motor Saver with the Traxxas 2.5. For the T-Maxx this setup works well. However the Motor Saver filter neck for the Revo leaves a little to be desired, as the filter ends up being right against the transmission and not in the factory location on the servo box. I didn't care for this setup after using it a while, and from what I've seen neither do many people. I'm really not sure where this modification started, as I've seen it in many places. However, with a few minutes of time, you can have the best of both worlds in regards to the Revo's air filter.

First of all, you need a Motor Saver filter and a stock traxxas filter neck. I should point out that you can use the modification with many other filters as well. However the Motor Saver filter is usually the standard replacement, so it's what I'll be using for this walkthrough.

Next you'll want make a hole in the end of the motor saver filter. The hole should be 22mm (7/8 inch) in diameter. Drilling this hole may not be practical for some due to the shape of the filter. I suggest marking the area to be cut and use a Dremel if you think you may have problems. Use patience, and only remove a small amount of material at a time.

Once the hole is made, simply insert the stock filter neck into the Motor Saver filter housing. If you took your time and sized the hole correctly, the neck should fit into the Motor Saver housing snugly. For added security, or in the event you cut a little too much material, you can use some Shoe-Goo to help seal the two parts together.

Once the filter parts have been modified and fitted together, you can install them back onto your Revo. You'll now find that the filter once again resides in it's stock location.

There is another take on this air filter setup that some people have chosen as they may not care for the Motor Saver filter. I’m not about to enter that war, other than to say I never had any issues with the Motor Saver filter. However, I now use this other approach with my Revo air filters. The reason is that it uses an 1/8 scale filter element and allows me to have a common filter that I can use with any of my vehicles.

All you need to do is to use some Shoe-Goo to adhere the 1/8 scale filter housing to the Revo’s filter neck. Once it’s dry, you’re ready to rock!
