Save ur money on them heads, buy that electric fan that will free at least 20 or more ponies-something you'll defiently feel when you stomp on it and you wont even be creating anymore green house gasses than before....lol
P.S. Dont fret worrying about an electric pump on a daily driver, most out flow OEM factory pumps big time, now accessories and electric pumps?? thats another story.
Goodluck, Charles
