yeah, i get 18...but i have crappy ngks in it..got two ranges too cold, but if its by now, and not when it was sold, i would totally get 4500 out of it! that means yes, tree huuger lineup fit...and it would cost me only like 9k..not 14.5k...so i dont know...good idea? only if i turbo it and beat it to death! but not really, its a tiny car!
