Do I need to clean the mounting surface before installing this gasket?

Yes. Remove all old gasket material and carbon buildup from both the manifold and cylinder head surfaces with a gasket scraper or wire brush. A clean, flat surface ensures a proper seal.

Will this gasket fit my specific Nissan model?

This gasket is designed for multi-model Nissan fitment across the 04-15 generation. Verify your exact year and engine variant against the vehicle compatibility list before ordering to confirm fitment.

What torque spec should I use when bolting the header back down?

Refer to your vehicle's factory service manual for the correct fastener torque sequence and specification. Over-tightening can warp the gasket or manifold; under-tightening will cause leaks.
