## Description

The microGreen oil filter is the most advanced technological leap in engine filtration in 30 years.

By continuously filtering a small portion of the engine oil through the patented microfilter system, the microGreen filtration system allows your vehicle to operate up to 30,000 miles without changing the engine oil.

Review: Almost as good as a bypass system for the same price as a K&N - I can’t believe these are the first filters of their type. There simply amazing. You can deffinetly feel that they use heavier gauge steel on the casing of these filters than an average filter. And the filtering job they do is unbelievable. I put one on at 4K miles, drive for 20 miles and my oil was two shades lighter when I got home. Crazy. I’ll continue to buy these. Their filtering is far superior to anything I’ve seen.
Review: I wanted to say that I was happy at first with the filter - I wanted to say that I was happy at first with the filter,however ever since I have installed it I have had a oil leak coming from the gasket area. I have had to even use a filter wrench to tighten it in a attempt to stop the leaking. When I installed the filter there was no remaining gasket from the old filter and I had cleaned the surface area as well. New oil was used to lube the filter gasket prior to the install as well. Thank-you
