while you have the coil out i recomend you clean up and dirt/rust on them so they dont drop down near the plugs i also ligtly greased the seal with silcone grease


if you are also doing the plugs get your 16mm plug socket and a longeextension as they are deep down the bores and remove them no pictures of this but you should be able to figure this out



now put your new plugs back and and reassemble




and your done

I put NGK irridum plugs into mine for a few extra £ per plug (ngk 6046- DCPR7EIX)
