Is it necessary to set a proper gap on the Bosch Super plugs for an M30? I read what the right gap setting should be for the M30, just wondering if the Bosch Supers I have are appropriate already. I don't have a gap tool on hand and just wanted to check first to seen if I will need to run out and get one before I put them in. I've only just started doing all the maintence stuff on the car myself as another family member used to take care of that when he drive it. Thanks!
