Or8 people, recently i have given my omega 2.6 MV6 to a member of my family, so i have inherited a 2.5 v6 omega on an S plate with over 152,000 miles on its back (nick named star ship enterprise) i no am back back in the days of old with H/T leads goin down and rapping them in electrical tape till i decide whats the best option, the decision revolves around wether mangnicore leads and top rated spark plugs are worth the money (very expensive) and time to fit them (hand hurts after being stuck down back of engine to reach coil pack) i know the certain performance companies say to do this on the 3.0 Ltr, but is it worth on the 2.5, any body know anthing , Rgds Tech1
