Why did you get a Crawford or a Kinetix?

What aspects of the above had you "sold"?

 

I haven't seen the Kenetix but I can say first hand that the Crawford is very high quality.

 

these are my major pro's and con's...

Kinteix:
pro's = Zero Modification / life time warranty (as long as the company exists at least)
con's = PLASTIC???? (but apperantly it's better cause it's lighter and doesn't heat up)

Crawford:
pro's = Tested and "approved" by many people
con's = New Strutbar + Mod Engine cover.

The gains seem to be almost identical... can they both handle boost as well? Also, is Kintexi's material (plastic) an actual CON vs Crawford's cast iron?

didnt the kinetix have a problem with melting or is that an old wives tale? Since i live in texas that stuff scares me lol

 

Some "guy" let his Z idle in the sun for like three hours and reported that it melted. I would be surprised if that was the only thing damaged. The battery for one shouldn't be cooked at 350 degrees whatever the under hood temp gets to sitting there for three hours.

 

so provided I don't let the frikkin car "Cook" like the genius mentioned above, a Kinteix plenum isn't too bad?

 

First off it's cast aluminum, not cast iron.

Now the reason to get either, is with the stock plenum there is a design flaw with regards to the air flow to the cylinders. To clear the "Z" hood, and still allow for the STB, Nissan designed the plenum with an angle. In doing this, the rear cylinders receive more air than the front cylinders. Crawford noticed this, and was the first out with their solution. Other's have since followed. IMO, the Crawford solution was, and is still the best one out there.

And yes, I had one of the first Crawfords, and I now have a V4. The latest is the V5, and is all cast, rather than a modified stock plenum like the one I have.

don't even consider a kinetix. search the forums and look at all the issues people have with them....cracking, melting, rubbing on the stock bar, and the list goes on. Yes, you may need to get a new strut bar and take the engine cover off with a crawford, but much better than having your plenum warp or crack

 

Those are really old posts. Yes, earlier versions had problems, but ever since their V4 came out they have been rock sold (platic solid? ) Their customer service is second to none.

Keeping the stock engine strut bar, and even the engine cover (with the back two screws loose) is a plus. Matched with some Kinetix high flow cats, your Z will sound mean....

 

Read all the posts and make up your mind. My opinion is to stay away from anything kinetix. Plenum is plastic...enough said. Cats have bad welds, crack and burn out....enough said

 

Man, you are a piece of work. You are talking out of your a$$ and you know what? It stinks.

I've had the plenum and cats for almost a year now. They work absolutely fine. I am having a bit of a vibration between the heat shield and one of the cats, nothing that a well placed hammer can't fix in 20 seconds.

You, on the other hand, seem to read some posts, you parrot what they say even if they are 2 years old, and take them as gospel. If I were you, I would THINK before you post. Your posts will come out much better.

 

I'm glad you went back and cleaned up your previous post. You did it quick too so it wouldn't show an edit. Too bad I hit reply right after you posted the first time.

At least you are thinking a bit more. Now, stop reading old posts and repeating mindlessly, and you will have made another huge leap forward.

 

I will repost if it makes you feel better - this was my orginal post for all to view, no shame here: (don't know if I will get the words exactly right, but it went something like this)

"Go ahead and get the kinetix plenum. While you're at it, get a narrowband A/F gauge. That way you will have two sh!tty 'mods' on your car...oh, kinetix cats were recomend as well, that would make it 3."

The whole reason I edited the post was because I thought it would be more usefull to the originator of the thread why I wouldn't consider kinetix.

I don't want to totally bad mouth Kinetix, they do have good customer service and their new plenum sure looks pretty

 

Please advise what posts I am repeating mindlessly

 

Ok, advising (is that a word?)

I've had the Kinetix V4 (first and only plenum from them I've had) for almost a year, and I have not experienced ANY of these issues. I too read the posts about their V1-V3 and the issues with cracking, etc. But they have had several releases and their V4 works fine. No cracking, no melting, no rubbing the stock bar.

I have also read that a plastic plenum is NOT recommended if you go FI. This makes sense to me, and I wouldn't recommend it either. Their new SSV though..... sweeeeeeeeeeeeeeeeeeeeeet.

 

if you had a choice between a product that had NUMEROUS issues in the past and one that had NO issues at a comparable price, which would seem to be the most logical to purchase? Maybe it's my bad attitude coming out here, but if kinetix made the only plenum out there, it would be one thing. Since I have the option to by a plenum, or plenum spacer if you will, with NO past issues, I think it would be unsmart to purchase one with a less than perfect track record.

Oh, Zboater, please advise again on a post that I am repeating mindlessly as you have yet to do so, despite the fact that you think you just did. Maybe you can tell me https://my350z.com/forum/engine-and-drivetrain/93444-noob-question-cams-and-pulleys.html
Maybe not the best person to take advise from

 

Go research the new plenum again. Jury is still out on it and it is swaying towards less than a favorable verdict. But what do you care, it's all shiny and pretty!

 

Ok, so you dig up a post from 9/28/04 where I ask a question and you are holding that against me? So I didn't know, and I asked. Someone answered, and I learned. That is what people do when they come to these boards, unlike you, who apparently comes here to

TROLL!
