I went to the edmunds maintainance schedule that someone directed me for my 03 I35. The "replacing of spark plugs" didn't come up until 105,000 miles. Is this right? Also, I didn't see a replacement period for the fuel filter. How often is that supposed to be changed?

 

Hi there,

I just checked the maintenance log in my car glove box and it's suggested to Replace spark plugs (platinum-tipped type) @ 60,000 miles and for every 60k thereafter.

How much would these platinum-tipped spark plugs costs?

Thanks
