The SneedSpeed Cylinder Head Stud Kit is a smart upgrade for MINI Cooper S and JCW owners who want a stronger, more reliable engine seal—especially if your car runs on boost or high RPM. Stock head bolts stretch over time, but this 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.
Key Features:
- Fits W11 1.6 L Engines (2002–2008 R52/R53): Made for Mini Cooper S and JCW models, ensuring a direct fit.
- High‑Strength Chromoly Steel Studs: Made from forged 8740 chromoly for top-level strength under pressure.
- Reusable & Race‑Tested Design: Unlike one-time-use bolts, these studs and 12‑point nuts can be reused for rebuilds or upgrades.
- Better Torque Accuracy: Improves head clamping, reduces gasket failures, and helps extend engine life.
- Complete Kit with Nuts & Washers: Comes with hardened washers and nuts to ensure even torque every time.
