The SneedSpeed Cylinder Head Stud Kit - All our studs are 220,000 psi, centerless ground, heat treated, 8740 custom chromoly alloy to handle the toughest loads and high boost levels. For owners who want a stronger, more reliable head to engine seal—especially if your car runs on boost or high RPM. Stock head bolts stretch over time, but our stud kit provides consistent clamping force and better sealing to prevent gasket leaks. The studs are reusable, making maintenance easier and more precise.
This kit is ideal for those building performance street or track cars. It fits perfectly on 2002–2008 R52 and R53 models with the W11 1.6L engine. You’ll get everything you need for a solid, long-lasting upgrade.
