Hey, my 02 xterra needs plugs, how difficult to replace and best brand for preformance.
5speed with 120 on the od,timing and waterpump replaced at 110

ngk spark plugs... not to bad to replace, EXCEPT cylinder #6, this down under the fire wall, there is a posting on here somewhere on how to change it...

Platnm 1 NGK's are what you want.
