Frequently Asked Questions
Do I need to clean the mounting surfaces before installation?
Yes. Scrape off the old gasket material and any carbon buildup from both the manifold and cylinder head surfaces. A clean, flat sealing surface is critical for the new gasket to seal properly and prevent leaks.
Will this gasket work with my current exhaust manifold?
This gasket is designed as a direct OEM replacement. If your manifold is factory or factory-equivalent, it will fit. If your manifold has been modified or is an aftermarket header, test-fit before committing to installation.
What torque specs should I use when reinstalling the manifold bolts?
Refer to your vehicle's service manual for the exact torque specification and bolt pattern. Applying correct torque ensures even clamping and prevents gasket failure.
