2013 135is Plug Change at 75k miles
Just did the plug change on my 135is. I followed the 2011 335i N55 DIY with no issues. Gapped the plugs at .08 and the car runs great, no idle issues or fluctuations. Here are what my plugs looked like at 75k. I've had a JB4 for about 50k and run map 5. I do run 50/50 E85 and 93 pump when back in Texas and 91 when in Colorado.
