Installation Time: Afternoon
October 02, 2011
T'was time to replace the original Motorcraft Platinums. Pulled old plugs out - burn color great but wear errosion on the electrodes due to extended use. Installed the Iridium NGKs which restored power to the pony. Not sure if it is specifically the NGKs or just the fact that new sparklers were installed. Engine idles smooth at 600 rpm and pulls strong through entire power band. Note: must remove fuel rails to get proper access to the COPs. After installation, noted fuel leak between fuel rail and top of one injector nozzle. Pulled apart and found damaged o-ring. Replaced o-ring and all was good. Not a difficult job, just take your time and be methodical about what you do. Running NGKs in my boat (SB Chev) which cured problems from original ACs. NGK makes a good plug. Motorcraft still a great product, just decided to opt up to these to see what they would do.
