COP coil over plugs absolutely hate the things, yes they improve packaging but at the expense of reliability (they last 70-120,000 kms on average) and increased aftermarket parts profits they cost a pretty penny. Not questioning the benefits of COP (yes closer travel for spark to the plug) but Im not so worried that electricity needs to travel an extra 30cm or so to the plug. Much better and cheaper alternative....

Cheap as chips and no more expensive COPs to replace or worry about!
