Spark Plugs

Well the thread pops up from time to time and just realizing I've got 60K on my car I realized it's time to do plugs!

On the recommendation of FF I went with the Autolite 103's and gapped them to .055.

Take a look what I pulled out-



I was disappointed to find oil on both drivers side spark plugs, the pass side were both dry. I expected them to be dry - but there isn't enough there to warranty any further thought.

The plugs turned out to be NGK Iridium ITR5F-13 Laser plugs - I don't know if these are good or bad, but Amazon wants 12 bucks a piece for them

At first look I thought there were torched, but that is what the iridium plugs look like. They are not gapped properly either - but I will tell you that I noticed a very noticeable difference in MPG's immediately. Normally I can get the car to hover around 39mpg when I reset it and after the plugs I can easily get it to hang around 44mpg. I maintained that number with ~20 miles of morning rush traffic. I'll know what I'll get after the drive home, but on a Friday it will either be mostly 80mph with some mixed bumper to bumper shit.

Your factory Iridium plugs are good for 100,000 miles. That is why they cost so much. If you put in a copper plug they are only good for 30,000 miles. The Autolite 103's are said to give you performance gains. Did you notice any difference when you did the change?

I didn't pay attention to the idle quality as it was always fine. I will tell you that I immediately noticed much better MPG's. My first tank I drove 430 miles without filling up, granted the car took nearly 11 gallons, but I think that was pretty damn good.

My commute is 90% freeway and 10% highway and most of the time I'm doing 75MPH+ and the highway driving is usually around the 60MPH range and I can easily get 39.X on the freeway and when I have a good regulated 60MPH I can push the car into the 42MPG range.

I am ecstatic with the plug change - it was totally worth it and will pay for it's self in just over a month.

100k mile plugs are a myth. I've changed them out at 50k on every vehicle with them ... none of them looked good for another 200 miles.
