New set of NGK Iridium IX plugs, earthing kit and an induction kit. Managed to change the plugs hoping they would solve my low rev missing/hesitating but no. However, car drives much better and pulls stronger, so must have needed done. Can't change filter yet as waiting on some pipework and need to read the earthing kit fitting guide and it didn't come with any bolts/nuts so gonna have to see what if I can get some...
