Professional engine builders cut the oil filter apart after running a newly assembled engine the first time. They do this to study the filter element for trapped material. The type and material gives them a good indication of the internal condition of the engine. As you can imagine, it's a real pain to cut apart a filter full of oil.
Engine Chek makes it easy for the home and professional mechanic alike to check for foreign material in the engine. Just remove and inspect the filter the next time you change your oil.
