I prefer Champion but will consider others. What are the best plugs for a 1998 6cyl? BEst gap?

Wires? I have used the brand Champion makes with success in the past, should those be ok?

Use NGK, factory OEM/Stock plugs (Double Platinum). That is what I replaced with. Also use the tool provided with the vehicle to replace plug #6--almost impossible without the tools. Visit Spark plug, Spark plug wire, spark plug gap, spark plug cross reference and ignition wires at Sparkplugs.com and/or Nissan4Parts.com for part numbers. I tried the Iridium on my other Nissan and they don't do that good of a job.

Thanks for the info. am not sure about a tool that came with the vehicle though. I don't recall any special tools that came with it. #6 sure looks like a pain to get to for sure.

Look under the rear seat, right near the jack you'll find the tools. They are a part of the same tools you would use to jack up the car (at least one of them). The tools should also be mentioned in the owners manual.

After you've loosened the plug, use compressed air and blow around the spark plug. Do it one at a time as the sand blows everywhere. A fresh can of compressed air will work also.

Last thing you need is sand and dust getting inside the combustion chamber.

With #6, if you don't have the OEM tool, use a long extension and universal socket joint. A shorty extension may be needed, I can't remember if I needed it or not when I did mine.

Universal socket may not be neccessary, but it's nice to have flexiblity when it's that far back.

Can someone post a pic of that special tool? I did not find it

Pathfinder tool

You'll find the tool in the owners and shop manual under the area for general maintenance, changing spark plugs. At least I can find it in mine.

Directly from the shop manual:

This tool is much better than anything you can purchase--especially since the spark plug socket won't get stuck in the engine with the spark plug!

If you do not have the tool I recommend trying to buy it from the Nissan dealer.
