Hm... 0.1% difference in actual vs. stated.. to the positive. Shoot him!
We all make mistakes, man.
on the work though. What would be great is if we could all make something like this for relatives and non-immediate family/friends that looked aesthetically presentable, didn't change the vehicle's drivability, and still had a decent impact on mileage... kinda like changing your friend's light bulbs to LED or Fluoro bulbs when they don't know it.
Is it wrong to mess with your friends by changing the hidden bulbs in their house? I say no. It helps them, it helps the environment.. anyone that could get mad about that needs to get a hobby. Like helping to save the environment! LOL.
Anyway, back to the original idea: IF we could all get something that would aesthetically fit the vehicles of our loved ones, and give it to them for Christmas, it would be like giving the world a Christmas gift - Slightly cleaner air for all! And they'd never know it, they'd just think it was a cool thing for their car to add on.
