    2016 m3 2.0L 6spd. CS catback(I know I know), CS front strut bar, custom fitted spectre SRI and some flaps. Installed 2 weeks after signing my lease (the dealership hated me).

  3. 2014-2018 Mazda 3 Skyactiv Engine and Performance
    So my 2014 Mazda3 has 37,450 miles currently on it. I finally took a look at the spark plugs. They seem a bit black and smell like melted crayons (fouled?). I took these out while the engine was still pretty hot. How do these look to you guys?

I think I might go with Simota or Takeda SRI, and I don't have a clue as to what CEL is but I know it's a bad thing. Another thing I'm trying to find is headers and a down...
