Complete Zex dry nitrous 'smart' kit.absolutely everything included,only installed once,and sprayed twice.i am doing a high compression engine rebuild so im just taking the kit off and selling it.also i am throwing in a set of Zex spark plugs which they recommend using with the kit.they were also on the car for one night i used them.im pretty much just seeing if anyone would be interested in buying the kit,im not trying to get rid of it right away or anything like that,but if someone offers me what im looking to get then ill sell it. the price im looking for is $400 shipped and thats everything with the plugs.
