yes it is from the Z. runs about 90 bucks and you need to "extend" it a few inches for the FX since the engine sits further back. a bunch of folks just cut their stock FX accordian piece and this is what i am going to do as well. you can get one at any parts place that sells parts for the Z or dealers like grubbsrichy said:is that part off a 350z? if so, what's the part# and how much? thanks, rich
Agreed Brad--bradical said:this is more of a "fun to do" and "cool sound" mod than anything. you will probably get 6-10 HP at peak with both the tube and cold air intake. over the main RPM range it looks like youll have about 2 HP gain. really i found that it smooths out the acceleration and definately a PULL once you get over about 4000 rpm.
i think if you couple it with a new plenum that combo of the three will give you more of a noticable gain throughout the rpm range
