Just wanted to know when I should change my spark plugs?

I am at 76,000 KM...

 

Dealership told me the replacement interval is 105,000 miles.......I guess that is about 169,000 kilometers.

 

I'm in Iraq right now so I don't have my manual, but it should state it in there. I was thinking along the lines of 60K. I may be wrong though.

 

I never go longer than 50-60k on a set of plugs like these.

 

I know what the manual says, our spark plugs are supposed to last 100K
miles. On my last Nissan ('92 300ZXTT) I changed the plugs 4 times in the
125K miles I owned the car. Changed the timing belt every 60K miles and
changed oil every 2500 miles with Mobil 1 synthetic. It's really all about
how you want your car to run. I take care of my cars and they take care
of me....

I bought mine used but I am planning on doing kind of what you suggest. Dealership told me to replace at 105K but I'm doing the plugs and belts now at 69K. I had the coolant, rear diff, and tranny serviced at 64K. Obviously I can't account for what the previous owner did or didn't do, but I will do what I can to keep it running well.

 

time to get some NKG's!

 

Most plugs on todays cars will go 100K+, but like anything else, it's all about the comfort zone for the owner. It will never hurt to do it earlier.

 

I replaced them on the 05 sedan I traded for the coupe at 55K miles.
They looked very good!!! I think I wasted my money......

However, if you are going to check your valve covers to see if they are leaking oil into the spark plug chamber, I would go ahead and change the plugs since you will have done most of the work at that point.....

Check for oil leaks before your warranty is up!!!

 

i just replaced mine this past friday with about 62k miles.... spark plug for cylinder 2 and one other one was pretty charred and had oil on the threads... all others had normal spark plug ignition oxidation....

 

How many miles on your G when you changed them?
