Honda K Series Exhaust Manifold Gasket 18115-PNB-003

Genuine Honda K Series Exhaust Manifold Gasket 18115-PNB-003

Stop exhaust leaks before they steal power. Swap in this genuine Honda K Series exhaust manifold gasket 18115-PNB-003 and give your K-powered Acura or Honda the airtight seal it was born with. Honda’s multi-layer stainless-steel construction shrugs off extreme cylinder-head temperatures, turbo heat, and countless heat cycles without crushing or flaking like cheap paper composites. The precision-stamped fire rings match the factory port shape perfectly, so whether you’re bolting stock headers back on after a clutch job or installing aftermarket headers that retain the OEM flange pattern, you’ll torque down once and drive worry-free.
