Got my buddies at Nissan to hook me up with the install of the HFCs,
Have to say, very impressed with the Z1 HFC's, took them all of 45 minutes to put them on, very straight forward.
Immediate difference in sound when I fired her up, and the pull is definetley there as well.
Overall, very happy with the HFC's, congrats Z1 you did your research on these.
