Frequently Asked Questions
Do I need new hardware to install this gasket?
The gasket bolts to factory manifold studs — use your existing hardware if it's in good condition. If studs are damaged or corroded, you'll need replacements; refer to your service manual for stud specifications.
Should I clean the mounting surfaces before installation?
Yes. Remove old gasket material and carbon buildup from both the cylinder head and manifold surfaces with a gasket scraper. A clean, flat surface ensures a proper seal.
What's the return process if this doesn't seal properly?
Test-fit and hand-tighten before final torque. If the gasket leaks after proper installation, contact ModSupply for return options — we stand behind our parts.
