Captain Obvious - Spark Plugs
 

Got my United Stage 1 tune. I told the shop I would do the the spark plugs myself. We all know this is a must and I am sooooooo happy I did. Definitely peppier after the new sparks. Just look at the difference.

BTW, I can't believe how ridiculously aggressive this car is now in manual mode considering it's only a 4 banger.
