Fel-Pro Toyota Prius ES 72197 Engine Cylinder Head Bolt Set

If you're rebuilding the top end of your Toyota Prius, Scion xA, or Yaris, you'll need a fresh set of cylinder head bolts. This set from Fel-Pro, part number ES72197, is specifically made for these applications. It's crucial to replace head bolts when you're taking the cylinder head off, especially if they are Torque-To-Yield (TTY) bolts, as reusing them can lead to improper clamping force and potential gasket failure.

Fel-Pro designs their gaskets and related components for the real-world repair environment. This means they account for imperfect sealing surfaces and use proprietary materials to ensure a reliable seal. This bolt set is application-specific, meaning it's validated for fit, form, and function to meet or exceed original equipment specifications. You can trust that these bolts will provide the correct clamping force needed to keep your cylinder head sealed properly.
