Fel-Pro Kia Optima ES 72211 Engine Cylinder Head Bolt Set

If you're rebuilding the top end of your 1999-2005 Hyundai Sonata, replacing the cylinder head bolts is a critical step. These Fel-Pro ES72211 head bolts are designed specifically for this job, ensuring you don't run into the same issues that can come with reusing old, stretched bolts. Many modern engines use Torque-To-Yield (TTY) head bolts, which are designed to stretch a specific amount during installation. Once stretched, they can't be reliably reused, and doing so can lead to leaks or even engine damage.

Fel-Pro understands the challenges of real-world repairs. That's why these bolts are application-specific, meaning they are made to fit your Sonata perfectly, meeting or exceeding original equipment specs. This ensures a proper seal when you torque down your cylinder head, giving you peace of mind that your engine will run smoothly. You can trust Fel-Pro for well-built parts that are validated for fit, form, and function in the repair environment.
