Spark Plugs

Blowout is known to happen, there are no statistics to determine exactly how common.

You can prevent it by torquing your plugs to spec and checking them periodically.

Ford sell us a G series plug with more threads now which may reduce the probability of spark plug blowout.

Old part: AWSF-32PM
New Part: AGSF-32PM
The one I use: AGSF-32C (copper instead of platinum)
 
Hey guys, thanks for all of the suggestions, I found my maintenance manual and believe it or not the spark plugs don't need to be changed until 100K miles. :nice: So I have quite a few miles to go!!! I will check the plugs to make sure they're all snug.
 
I believe service recommendations are 60,000 miles. as a genera rule of thumb. Thats when i plan on changing mine...even IF they will last 100,000.

I'm a freak like that, i always am doing unecessary maintenance :nonono: I even have a whole book i bought to keep track of everything i do, install and buy for my car....
 
Personally I change my plugs every 3-4k depending on how much or if all I was spraying the car. I use the NGK TR6s. But if I know i'm not running any nitrious I change it every 10k.<regular copper plugs> I have a cobra so its very easy to change. Plus i like changed plugs because gives me an idea whats going on in the block.
