Professional-Grade Head Studs for Mazda Miata

The Mazda Miata is a legendary platform for both track enthusiasts and turbo tuners. However, the factory head bolts can struggle to keep the cylinder head sealed when you increase power or track the car hard. The ARP Head Stud Kit (218-4701) is the ultimate upgrade for your 1990-2005 Mazda Miata engine.

Engineered for Performance and Reliability

• Fits all B6 and BP engine variants from 1990 to 2005.
• Made from high-strength 8740 chromoly steel for superior durability.
• Provides significantly more clamping force than standard OEM bolts.
• Prevents head gasket failure under boost or high-compression loads.
• Includes hardened parallel washers and nuts for even load distribution.

Whether you are building a naturally aspirated track car or a high-boost Mazdaspeed turbo setup, these studs ensure the cylinder head remains perfectly seated. The increased clamping force helps prevent the head from lifting, which is a common cause of head gasket failure in modified engines. This kit is a direct replacement for your factory bolts and is a must-have for any serious engine rebuild. With ARP's reputation for quality, you can be sure your engine is protected against the stresses of high-performance driving. Upgrade your Miata today with the best hardware available at GGCRACING.
