how much are for spark plugs for my car?? and what kind should i buy model # or something?? i know nothing about this... i just want to change them... also where are they located in my maxima... please help.

thanks.

 

1) Remove front bank rocker cover ornament.
2) Disconnect six ignition coil harness connectors. Three are found under
the ornament. Three more are found nestled among the plenum runners, in
plain view, closer to the windshield than the three which were hidden under
the ornament.
3) Loosen ignition coil fixing bolts and pull out six coils from the intake
manifold connectors.
4) Use a spark plug socket, a long extension, and a ratchet handle to remove
the spark plugs.
5) I recommend using a tiny dab of anti-sieze compound on the threads of the
new spark plugs. I've had good luck with Bosch platinum spark plugs.
This recommendation is controversial. Some other contributors to this
forum insist that the original equipment brand is preferable.
6) Tighten the new plugs to 14 - 22 foot-pounds.

 

What should the gap be on the plugs? I have 30,000 miles on my GLE and I would like to check there gap and adjust if necessary. I currently have NGK PFR50 I think these are origanal plugs they look nice and cocoa brown. What is the plug number of those Bosch Platinum plugs?

 

Nissan specifies 0.039 - 0.043 inches. The factory-set gap on platinum plugs seems to always be "spot on". However, when you are installing new plugs it doesn't hurt to check.

The color sounds right. Tan to brown is good. Something like coffee, extra light. If the car is running well, don't bother adjusting the gap. Modern electronic ignitions deliver such a good spark that plug gap is not important. You could run plugs with double the recommended gap and probably not notice the difference.

Don't know. When I buy plugs, I look it up on the chart. Platinums last 60K or more, so I don't buy plugs all that often.

 

i put in split fires in mine, cost about $35. Not bad plugs
