My 03 MDX has about 73K miles on it and has been feeling a bit sluggish lately. I decided to do some easy maintenance items to see if they make a difference. So over last Saturday morning, I popped the hood and went to work... changed my plugs and air filter.

Took some pictures of the old plugs and filter:







Here are the replacement plugs:


I've been driving it the past couple days and there's a noticeable difference. The car idles better and accelerates smoother. Also, I seem to average about 1mpg better with the same driving habits and route to work.

Take away? Simple maintenance works!

ductrinh,

Q: Can you give us DIY'ers a play-by-play on how to change the spark plugs? Any special tips or tricks when working with the MDX?

Please let me know.

The original Bosch platinum plug is garbage. The newer platinum +2 or +4 looks promising, but the problem lies with the super thin center electrode that's almost totally hidden by the insulator. They foul much easier than other plugs.
