Review on 🚗 Enhance Performance with Moroso 85481 Air/Oil Separator Catch Can Kit for GM Trucks, Silverado/Sierra/Tahoe/Suburban, 14-18 2500 w/Gen IV Gas Engines by Choice Maynard

. Installation was easy and the suggested install location worked perfectly. I now have a little over 3,000 miles since install and get 1 ounce of used oil per 1,000 miles. At the same time as installing the Moroso I did the following: 1) new spark plugs, 2) new spark plug wires, 3) cleaned the throttle body, 4) spilled Seafoam inlet cleaner through the throttle body. The results were: 1) 2-3 mpg better gas mileage, 2) clear engine shudder issue fixed. Gas mileage was compared based on the 4-hour, 250-mile round trip I take each week to visit my 99-year-old father.
