A gasket may represent a small part of your engine investment, but its job is critical. Building a high performance engine takes more than a combination of premium parts; as boost levels, temperatures, and cylinder pressures increase, the demands on your gaskets increase with them. SpeedFactory Racing’s copper gasket lineup addresses two critical sealing points: the cylinder head and the exhaust manifold. Properly sealing combustion pressure and exhaust energy are essential to maximizing your combination’s performance and reliability.
Uncompromised Exhaust Manifold Sealing
Our Precision Fit Copper Exhaust Manifold Gaskets use solid copper construction with embossed sealing beads around each exhaust port. These raised areas concentrate clamping pressure where it matters, while copper’s conformability helps accommodate minor surface irregularities.
Available for Honda/Acura B, K, and D-series engines, these gaskets provide a durable, reusable sealing option for demanding street and racing applications. Proper installation, flat mating surfaces, and retorquing after the initial heat cycle are essential to getting the best results.
Cylinder Sealing for Maximum-Effort Builds
For high-output B and K-series VTEC engines, our Fire Ring / Copper Head Gasket Kits combine a copper gasket with individual beryllium-copper fire rings to contain extreme combustion pressure. Wet-deck and dry-deck options let you select the configuration that matches your engine’s cooling system. This is a purpose-built ultimate combustion sealing system where each component plays a vital role in maintaining the best seal possible under the most demanding conditions.
