Random question, ive read loads and loads of posts about coil packs and how prone they are! I think this is what is wrong with my car but when i took mine out the other day to clean them I noticed that the "stalk" of the coil pack has a diffrent part number, i googled it and found out they are replaceable and separate from the coil packs. But ive never heard of anyone changing these only changing the coil packs with new ones of these with them. So basically what im getting at is that these are effectivly ht leads connected to the coil packs, on most cars coil packs dont go that often its more often then not the ht leads.
So im curious if anyone on here has ever tried changing just these for new to see if it solves any issues? has anyone else ever noticed this either?
