I saw a posting here a while ago regarding plugs, and specifically the Bosch 4 electrode type, where there is a grade available for the Impreza Turbo? The posting was from a guy in the U.S. Has anyone here in the U.K. tried them, and if so, how did they perform? I`ve used them on other cars in the family and they seem good, but changing plugs on a Scoob is not a five minute job, so anyones experience is most welcome!

NGK all the way. We at Mac's Power Motorsport wouldn't use anything else. I have a standing order for 5 service kits per week from my local Subaru dealer and last week he sent me Bosh instead of the usual NGK. They are going back. Maybe others have good experiences of them but we have not.
