New 1/8 scale 3 stage filter for stock and high horsepower engines.  Fits securely under body and absorbs high impacts.

This filter runs longer between cleaning and has higher airflow than any filter we have tested.
 
Motor Saver gave out filters to racers all over the world for six months of testing before putting this filter on the market.
 
We received a call about this new 1/8 scale off-road filter from Otto Alison, owner of Alison Offroad RC Raceway in Littlerock, Arkansas.   " We found the filter worked better than we thought it would.  We got a full minute more of run time.  We also noticed that we needed to richen up the carb.  We got better overall performance with this filter.  The filter did not have any dirt in the inside foam after running all day.  We have a groomed track which we keep wetted down."
 
This new three stage 1/8 scale filter was designed to run in fine powdery dirt conditions.  NOTE:  First check inside foam every two tanks of gas.  When inside foam shows dirt ring more than one eigth of an inch it is time to clean.

Filter now comes without oil on the outer black foam element and pre-oiled white inner element.

Conditions for oiling outer black foam:  Track or field that has fine silt or clouds of fine powdery type dirt you need to oil the outer black element.

Check the inside foam element every two tanks of gas.  If, the inside foam at the bottom end where the hole is has a dirt penetration of more than 1/8 inch, it is time to clean.  If, you get the 1/8 inch dirt penetration after just a few tanks of gas, you need to oil the outer black foam element and clean the inner foam element.

Light powdery dirt or hard packed clay conditions:  We still check every two tanks of gas until we see how fast the inside dirt ring is forming.  Note:  Motor Saver runs two 1/8 buggies with lots of horsepower.  We can go all weekend of racing in light dust conditions without cleaning the inside foam element or oiling the outside black element.
 
Filter rubber base with tie-strap must fit properly to the truck/buggy carburetor.  You should be able to hold onto the rubber base and lift the truck or buggy all the way off the ground without the filter base coming off.

If, base comes off you need to check inner groove in rubber base and carburetor groove.  When base goes over the top of carb it should have a snap type fit.  The rubber base groove should fit inside the groove of the carb.  If, the rubber groove is too high, and when tie-strap is tightened down, the base will not have a mechanical fit.

We make a rubber base kit for 15mm and 16mm carbs.  There are three different inside grooves.  If, this still does not pass the lift test please give us a call.  We are working on more rubber bases to fit different carbs.
