The first time the Team saw the X-pect air filter and airbox they knew what they wanted to improve. They knew because somebody a time ago had come up with a great idea that worked. Credit for the idea goes to………

Thanks for posting it!

Filter frame after paper has been cut away with razor blade and Utility knife.

1 inch foam filter material marked by filter frame with magic marker and cut on the outside of black line made by marker with bread knife and a straight edge. Cutting on the outside edge of the black line helps so filter fits tight in the frame to prevent leaks. A sealant around the edges could also be used between the filter and the frame but it would not then be removable for cleaning and oiling.

The filter installed is 1.19 inch thick cut down from a generator filter purchased on Amazon. Uni foam filter media is also available on amazon in sheets. In the picture upper left top corner two pieces of it can be seen and combined it would equal around 1 inch and it comes in several sizes of filtration. The Team believes at minimum you need a layer size of 60-65 Pores per square inch (PPI) saturated with filter oil, OIL is a requirement. You could mix and match two sizes of filter media to increase air intake or increase filtration.

Oiled and fitted into the airbox.
