Ok what is a plenum for the 350z i have never heard of it for any other car. What does it do, i think its for air intake. Is it similar to intake manifold?
it is the part that is on top of the motor, big silver piece and has the engine cover to the front of it, right under the strut bar. the throttle body attaches to it
I have seen and heard of more than a few peoples plenums cracking(kinetix). Thats why they are making a 3 version already.. Thanks for the heads up about toykilla.

I like their price a lot better then the crawford plus you get to keep your stock one. But I would defintaly wait for all the bugs to be fixed if I was buying one.
This is a Crawford plenum and strut brace (stock strut brace doesn't fit). Excellent mod, good bang for the buck. The stock plenum slopes down in front, so the front 2 cylinders are starved for air. Crawford fixes that.
Either crawford and kinetix make intake plenums. This is the upper plenum-- the upper part of the intake manifold. Basically they are a bit taller allowing more air, and both optimize airflow to each cylinder, the crawford being flowbench proven. Both have put down consistant power on dyno's, so it's just a choice. Personally, I went Kinetix because with the crawford, you have to pay for a replacement strutbar (if you choose so) and, if you want to keep your stock plenum, that also costs about $200.
It's true that you have to send your OEM plenum after you receive your Crawford one, but I can honestly tell you that mine will never come off my car again as it looks stock. Then again, I don't plan on selling my car...
I paid the extra $200 to keep my stock plenum, when I bought the Crawford plenum. That way, I got my Crawford plenum faster. He just went out and bought a new plenum core and welded mine together.
In the grand scheme of things as it relates to how much money I have spent modding my Z, $200 isn't really that much. And I can put the car back to stock when it comes time to sell it.

There hasn't been any performance review with this manifold and keep in mind that you would loose your low end torque.
Here is an intake manifold that I have been waiting for. Kinetix Racing made this prototype aluminum intake manifold. This would be a perfect application for a forced induction car, unfortunately they have yet to release a production version. They are currently taking care of the orders with the plastic plenum they developed.
I have contacted Kinetix Racing a few times regarding the progress of this plenum. They have told me as of 3 weeks ago that they are going to be focusing their attention back to this prototype plenum to develop it further for production. Maybe we will see it by the end of the summer, who knows? But I will be waiting as long as necessary...
They never released any information regarding the horsepower increase with this plenum. Also they said that they wouldn't make the plenum available for sale until they did so.
Hello,
Is it possible to install Z1 High Flow Race Intake Upgrade Kit for Z1 or Stillen Gen 3 for Item # 377242617 Injen® - SP Series Cold Air Intake System . Also replacing the crash bar modification for the one that z1motorsports sells. I have a Nissan 350z 2008.
I am looking into installing the isr performance ep dual tip exhaust on to my 350z and was wondering if I unbolt the stock exhaust from around the middle on the car and just bolt the new one on straight back I'll put a pic of where to unbolt. Also could someone tell me if the isr exhaust would...
Little new to the Z scene
Currently running berk test pipes and fairlady exhaust, not really liking the rasp around 4k rpm...
Wondering what exhaust has a deep sound? I hear the greddy evo is deep, but is there any others or another way to kill the raspy sound?
Thanks guys.
