A: Yes. The EC781 billet cap fits both 6.0L (2003-2007) and 6.4L (2008-2010) Powerstroke engines. Same oil filter housing across both generations. Q: How is this better than OEM plastic? A: The OEM plastic cap cracks, swells from heat, and strips at the hex. The billet aluminum cap eliminates these issues permanently with metal that doesn't degrade. Q: Do I need a special socket? A: No. Standard 36mm socket. The OEM plastic cap also uses 36mm but often strips because the plastic rounds off. Q: Can I reuse this cap? A: Yes! The billet cap is a permanent replacement. Simply unscrew, swap the filter element, lubricate the O-ring, and reinstall. Torque to 18-22 ft-lbs. Order your iFJF replacement part today and experience the quality difference.
