Replace your Gen 1 Coyote header bolts with the correct thread
The Kooks BK112 is the coarse-thread replacement kit for the listed Gen 1 Coyote 5.0 header application. It supplies sixteen stainless bolts with M10 x 1.50 threads and 25 mm length, making the thread specification clear before you order the fitting hardware.
SKU: BK112
Choose by thread, not engine name alone
The M10 x 1.50 pitch differs from the M10 x 1.25 fine-thread kit. Match the actual cylinder-head threads to the kit, particularly where an engine or head has been changed.
For service or replacement fitting
Use the kit when matched header hardware is missing or damaged. New Kooks header packages generally already include their bolts. Follow the application fitting instructions and heat-cycle checks.
