Do I need hardware or adhesive to install this wrap?

Installation hardware is not specified with this product. Test-fit the wrap first to determine if you'll use tie-downs, clamps, or adhesive based on your specific wire routing and engine bay layout.

Can I wrap multiple spark plug wires with one blanket?

This is a single 6" wrap. Multiple wires or longer runs will require multiple blankets. Measure your wire bundle length before ordering to confirm coverage.

Will this wrap melt or degrade under extreme engine heat?

The titanium and silicone construction is rated for high-temperature environments. However, direct contact with manifold surfaces exceeding extreme temperatures may affect longevity—position the wrap at a safe distance from direct heat sources where possible.
