NGK iridiums are great.I believe that the part number is ZFR5F-11. I know the turbo ones are ZFR6F-11. The NA ones should be 5F. The plugs are insanely easy to change. Check the how-to section, but basically you just undo the 10mm bolts that hold the two coil packs on, pull the plugs out. The car has a slave system. 2 coils each controlling 2 plugs. Then use a deep socket to unscrew the plugs (...
