Description Reviews MINI added Coil-On-Plug technology in 2007 eliminating wires altogether to make a better working system. The problem is, more so in the Coopers than the Cooper S's, is that we found that MINI keeps their spark plugs in longer than they should based on recommended service intervals. That in turn makes the coil pack work harder to make sure the cylinder is working correctly. That then burns out the coil before it should ever need replacing. How do you know if you need a new coil pack? The car will give you a SES light (Service Engine Soon), as well a rough idle, and once you read the codes it comes back to a misfire or coil pack for cylinder X. A surefire way to know that it is the coil pack is to move it to another cylinder and see if you get the same code for that new cylinder #. We have seen Cooper's with coil problems as early as 60K. The MINI Cooper S's are not immune to this problem, but we have been finding that it is in less numbers and higher mileage. We highly recommend replacing the spark plugs at this time also. The coil pack warranty will be void if you do not replace the spark plugs, per the manufacturer's warranty. You don't always have to replace all 4 coils at the same time, but you should. Also, to help save costs, we will be selling you the same coil in the car; a Bosch or a Delphi unit. But it will not come in a MINI box. It comes direct from the manufacturer to take out the MINI markup! Note: Sold as each. 1 Review 5 Coil on plug pack - good stuff Posted by JASON D on 15th May 2018 Developed a massive at the minis on the dragon and Chad and Nick from Detroit Tuned saved me with their last coilpack enough for me to limp home and replace the other 3. I recevied BREMI units, and i think my '08 r56s originally came with Delphi. But it's running better than ever.
