I purchased this chip for my 2012 Honda Civic Si and the chips works great. Instantly I felt better throttle response and it work very well. I have not got a dyno yet, But I am beating my friends of the line with the chip better than I did before and I only have a Cold air intake and this chip in it. It sounds throater and has a much better pick up. There is a low side for better MPG, but I have not used that yet. I recommend this chip for This model Civic any day! Keep up the good work Performance chips Direct and thanks for offering the best chip for a great price.
Thanks
Chase
