I have a 2017 c300 4dr sedan and i want to do an e85 conversion kit but just don’t know where to find the conversion kit and the best one for performance? Also, has anyone ran a e85 conversion kit in their c300?

you aren’t going to find a kit, for starters the fuel system won’t let you run e85. On stock turbo you may be able to run Close to e50 mix with tuning or course. Spool performance is only company that makes the hpfp that can handle it. Start off with that and gradually work your way to full e85. I don’t think anyone has run full e85 on a m274 engine yet so nit a lot of info. I imagine the lpfp would need to be upgraded as well for full e85
