Even if they come already gapped I would take the time to check them.

Click to expand...

A feeler gauge or a little tool made specifically for plug gapping. They are cheap. $5 tops.

Do a search on spark plugs and you should come up with some detailed instructions.

Go to any Auto Zone or Napa and get these parts and tools (if you don't already have).

1. Spark Plug gap tool
2. Spark Plug wrench (if not that, then a swivel for your socket and a long and short extension)
3. Anti-seize for the spark plug boots
4. Spark plug grease

There are a couple of plugs that are a PITA to get to, so just be patient and take your time. My suggestion is to start with the driver's side plugs as they are the most accessible so you can get used to the process and how hard to pull on the boots. Oh yeah, you'll also need a screw driver to remove the boots. Do not overtighten the plugs. Once they feel tight, give them about 1/8 of a revolution with your wrench. No more or else you could strip them. Finally, always check the gaps to make sure they are up to the manufacturers recommendations. The only exception to this is if you get a set of Denso Iridium plugs as they come pre-gapped and are very easily broken with their tiny tips.

Hope this helps.
