## Description

X002278 Donaldson Original Informer

Review: Keeping performance at its peek - In my motorhome i use a type of air filter that is of the style that when it becomes restricted its imperitve that it gets cleaned so as to reduce poor fuel milage an performance. It was very important for me to know when the filter would cross that threshold, i discovered that the original restriction gauge had long since quit since i discovered the filter being VERY dirty while performing my last service. For just a few dollors for this gauge i am confident i just save several dollors that i would have been spending on fuel an maintence.
Review: Identical to the one I replaced - Air filter monitor on my Kawasaki Mule. The other one broke. this one works fine.
