Instead of the softer stock material, iFJF uses billet aluminum plus an upgraded stainless steel drain screw, making routine service and drain operations more reliable.

It suits anyone replacing a damaged OEM cap, upgrading weak drain hardware, or seeking a long-lasting component that stands up to repeated filter changes. If you expect heavy use, harsh environments, or simply prefer stronger service parts, this cap is a practical, direct-fit option—remember to source a compatible O-ring if yours needs replacing.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this cap include the O-ring gasket?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No, the O-ring is not included.
