If they are over 60,000-80,000 miles maybe else no reason. They usually last 120,000 or more with a spec of 100,000. Use only OEM equivalent when you do. I didn't and replaced those in 1/4 the distance of the first set (and chased misfire codes for a while not anticipating 25,000 mile plugs to be the cause)

Answer to OE Poster's question:
Yes, replace the plugs when doing a cam/valve cover gasket seal replacement. Cheap, easy, check your coils for over heating (burn marks on the top near the epoxy edges), replace as required. Suggestions on plugs NGK Iridium Part No: BKR6EIX Gap: .032" Torque: 20-22 FTLBS Yes, add a DOT of anti-seize to the threads If your vehicle has the older style coils with replaceable coil/plug boots, replace them. Match the replacement with the coil brand that you have (Bosch or Bremi). These plugs will give you a better idle quality, cleaner tip in acceleration, and depending on your driving style, a little better fuel economy. Sorry no HP gains except new plug VS old plugs. TIP On the gasket install, add silicone sealant around the half moons on the back of the head. Clean the grooves in the cover before installing and inserting the gasket. Do not trap the vacuum hose to the EGR under the cover on install, double check for any wires being trapped as well. Tighten the cover finger tight, let the sealant set up for 20 mins, then torque the bolts in the center out to the ends. Lots of tips in the DIY articles above on this repair. See Images below for plug and coils....
