I have a Zex kit that i am going to have professionally uninstalled in a few days. The kit was professionally installed only a few months ago. I have not even gone through one bottle yet. It is in perfect condition, i am going to sell my car and that's why i have to sell it. I'll let it go for 375.00 plus shipping.

ohh yea, it was installed on a 99 civic ex and it made a major difference in power even with just a 55 shot.
