350z plenum

May 11, 2004 Last reply: 22 years ago 4 Replies

I installed a Borla exhaust today with Nismo headers. Looking at the intake right now. I like the looks of the Kinetix unit but have heard stories of the plastic cracking from vibration, etc. Anyone have experience (good or bad) with these?



I looked into Crawford but they are not readily available.



Cheers, M.



I have not. but please keep us updated.

Kinetix has done a very good job of addressing the cracking problem. They're now shipping version 3 of their plenum, which includes the mods to version 2 (brass sleeves in the moun points) and certain manufacturing inconsistencies have been fixed (hole allignment, improved molding process).

I've had version 2 on for about a month now and there are no problems to report. Even now that outside temps have gone from freezing to the high

80's.

Since when has Doug at Crawford had production problems? Kinetix doesn't work with FI or N20 Crawford does.

I have ran my Crawford plenum N/A, N20 and now 9 PSI FI perfectly.

Kinetix is good but they can't do that and turn around from time of order is only about a week with Crawford. You won't have cracking worries either or the other problem I am reading lately about blockages from the mold.

I am "on the list" with delivery expected 1 month or so out. This is fairly unacceptable to me hence I'm looking in to other possibilities. I don't doubt the quality of the Crawford unit. Thanks!
