MotorSavers are USA made and patent. Alot of hitech research was done on
the unique mesh screen housing and the foam filter. They will allow your engine to breath better with out clogging due to the screen mesh housing and larger foam suface area. Stock air filters are usually made in China. Racers and people at the track are always amazed when I pit at 10
minutes-plus. They will increase your engine performace and
mileage. I bring atleast two to the track; one for practice and qualifying and one for the mains.
