Fel-Pro Nissan Frontier ES 72231 Engine Cylinder Head Bolt Set

If you're rebuilding the top end of your 1993-2001 Nissan Altima, Frontier, or Xterra, or your 1991-1998 240SX, you'll need a fresh set of cylinder head bolts. Fel-Pro's ES72231 engine cylinder head bolt set is made to meet or exceed original equipment specifications, ensuring a reliable seal when you reassemble your engine. These bolts are designed specifically for the repair environment, meaning they account for imperfect sealing surfaces and are manufactured with proprietary materials to handle real-world conditions.

It's important to replace head bolts when you remove the cylinder head, especially if they are torque-to-yield (T-T-Y) type, as re-using them can lead to improper clamping force and potential sealing issues. This set is validated for fit, form, and function, so you can be confident it will install correctly and perform as expected. Fel-Pro is a well-known name for providing dependable sealing solutions for your vehicle.
