The Kooks Cometic MLS (Multi-Layer Stainless Steel) header gaskets deliver leak-free sealing for all Chrysler, Dodge, and Jeep 6.1L SRT8 and 6.4L 392/Apache HEMI engines (2005–2023 300C, Charger, Challenger, Magnum, Grand Cherokee SRT8, Durango SRT, etc.), featuring a 3-layer stainless steel construction with embossed sealing beads that withstand over 1,800°F and repeated heat cycles without blowing out or crushing.
