I have been doing a number of scheduled maintenance items and decided that the spark plugs were next up.
I struggled with staying with the original copper plugs or upgrading to platinum, double platinum or even iridium.
In my research I found that Autolite has a mail-in rebate
program for their spark plugs so I decided to use their AP5263 which is a single platinum. Cost each from Napa was $3.19 and the rebate was $1.25 each making a final price of $1.94. Not too much more than the standard copper plugs.
It seems the biggest advantage for any of the upgraded plugs is extended life. The single platinum plugs I installed said they had a 3 year life span. We will see. The plugs I removed had over 52,000 miles and had a perfect light tan color. There was a slight amount of wear on the electrode.
I will say the installation was a little difficult. Started on the drivers side. The last two sets were barely accessible so I decided to remove the tire and wheel well liner to get better access.
The passenger side was pretty straight forward. I did remove my TrueFlow intake and the stock air box.
Take your time. You will need at least 3 hours. Be sure to gap at .045". Because the threads on the AP5263's are not plated I made sure to use an anti-seize compound so there will be no issues down the road.
I figured I saved at least $150 by doing this myself.
