Frequently Asked Questions
Do I need anything else to install this, like studs or fasteners?
This is the gasket only. Your header bolts and any hardware are separate — verify what's already on your header or available in your toolkit before ordering.
Can I reuse my old header bolts, or do I need new ones?
Reusing bolts is common, but inspect them for corrosion or damage first. If they're pitted or seized, fresh hardware prevents installation headaches and ensures proper clamp load.
How long does this gasket typically last before it needs replacing again?
A properly installed gasket on a stock or lightly modified engine can go 50,000+ miles. High heat, boost, or repeated disassembly cycles reduce life — plan accordingly if your RX-8 sees aggressive use.
