As a fellow Prelude owner gave it the thumbs up, I'd thought I'd have it done on my Lude. I had it carried out on Saturday 12/10/13 at A.C. Auto Services (http://www.terraclean-sussex.co.uk). The only difficulty the guy had was trying to sort out the correct connection / fitment to connect the Terraclean device thingy to my fuel rail.hondansxr wrote:No probs car running great smoother too
Cannot praise it enough .get it done you won't regret it .
About a month later, I haven't really done many long trips, so can't really comment on fuel economy. However, one of the first things I did notice was it being more perky. A month later, I'm almost certain that it is indeed more perkier than before and does seem much smoother than before.
My dad had his 53 reg Lexus IS200 Sport done at the same time and he reckons that fuel economy has improved.
