Fel-Pro 15-20 Subaru WRX/13-20 WRX STI/17-20 Toyota 86 Engine Cylinder Head Bolt Set

When you're rebuilding the top end of your engine, especially on vehicles like the Subaru WRX, WRX STI, or Toyota 86, using new cylinder head bolts is crucial. This set from Fel-Pro includes all the necessary bolts to properly secure your cylinder heads. These are designed to replace Torque-To-Yield (TTY) bolts, which should never be reused after the initial installation because they stretch to achieve clamping force. Reusing them can lead to improper torque and potential gasket failure.

Fel-Pro has a reputation for creating parts that work well in the real-world repair environment. These bolts are application-specific, meaning they are made to fit your particular vehicle's engine without modification. They meet or exceed the original equipment specifications, ensuring that you're getting a part that performs as expected. This focus on fit, form, and function helps make your engine rebuild a more straightforward process.
