No. That's what I have on my 2.0L. It is just very laggy. Even with the header. I previously had a FP 18g. I would recommend the Deadbolt 18g due to the extra coatings and reuse of stock water and oil lines. The FP had to have different oil and water lines. The 18g is a perfect fit for a 2.0L. There are days that I wish I still had mine.
