What kind of coils did you use? OEM or aftermarket? I am interested in eventually replacing mine for my mpg project research and would like to know what you used to get those results.

oem coils.

I saw the biggest change when I de-carbed did a oil change put in the plugs and coils that's when the mpg's shot up.

Mine has a problem. It says Highway rated 24 mpg...but I just drove it around and got 28! What's up with this crap?

I gained about 2-3 mpg by changing to a new air filter but then again it was so dirty that a concrete block probably had more airflow than the old filter...also about to change plugs and coils hoping for another mph or 2

I get 20-21mpg average in my daily driving. 2005 with manual trans. When I first got it I drove it hard and got 15mpg. I hated the low mpg so I installed a ScanGauge II to monitor the results of my driving. With a few modifications to my driving habits the mpg increased significantly.
