EngineQuest has developed a new oil filter adapter with an internal hex design for the 2003-2008 Dodge 5.7 liter Hemi. The newly designed oil filter adapter allows the use of an Allen wrench, which greatly reduces the potential for damage, and the time and labor required to install or uninstall this adapter. This design innovation by EQ marks the beginning of a complete conversion of the company’s entire line of threaded adapters to the more practical hex design. The hex designed Dodge Hemi adapters (part#OFA345) are available now. EQ also offers engine builders a large selection of OE fit oil filter adapters for AMC/Jeep, Chevrolet (small block), and Ford engines, and has recently   introduced oil filter adapters for current AMC 304/360/401 liter engines (part #OFA304).
