So my girlfriend has a bone stock 2012 cruze with the 1.4 turbo. Changing her plugs to try to reduce some of the turbo lag its horrible in warm weather with the ac on. I saw the hesitation sticky and is the BKR8EIX-2668 or BKR7E-4644 still the way to go? I saw this post was from a few years ago and I cant read through 115 pages. Thanks!
