I just completed a 830 mile trip, almost all interstate. My fuel econmy averaged almost 25 mpg this is a 10% improvement. The improvement was probably a little better than 10% since there were 3 of us insted of the usual 2 and the weather was mild, I believe in hot weather the improvement will be even greater. The power increase also is noticable.

I think this modification is worthwhile, I should have done it a long time ago. I know 10% does not sound like v large increase but it is huge. <img src="/forums/images/graemlins/kewl.gif" alt="" />
