first off im alittle mad because i obviously dont have what i paid for yet.

here's the story. i ordered the v.4 plenum from kinetix about 2 weeks ago by paying for the 2 day air mail. i got the shipping confirmation email and it said my order was ground shipped. so i called kinetix and they refunded me the difference. next about a week later i get my package, i open it up and it is the high flow cats. i have mixed emotions. i have the stillen race pipes right now and i really would rather the high flows by kinetix. so im thinking just call kinetix and say, hey where is my order for the plenum and i would get a great steal. but i'm not that type of person so i think i am going to be honest about it. so i called them to see what type of deal we could work out and they didn't answer. What should i do? im definitely gonna get the plenum but do you guys think there is any way they will let me keep the cats for free because of my trouble?

thanks. jim

 

I doubt they will let you keep the cats. They might cut you a deal but thats about it. Try to get a discount or something on them.

 

If you ask me, I would not get their plenum until they release their Aluminum (F/I) version. Keep in mind that I myself have a V4 on my car and so far have not had any problems with it. It did however raise my engine cover up enough so that the hood nod rests directly on it so there is a nice big gouge in it, but that's another story for another day. I used to support KINETIX, and I guess I still kinda do, but if this plenum cracks like the previous versions (which sadly I feel is ineveitable) I will be requesting a refund and just run my stock plenum. Crawford is an option, but there are too many other factors when you go that route (core charge, losing the stock strut bar, etc) so I personally wouldn't go that route either.

Keep the cats if you can work something out with them. I have those too and I guess they do something. Can't really tell on the butt-dyno.

At least they haven't cracked... yet

 

i feel the same way about the crawford plenum, thats why i want the kinetix plus i think this one will last. but i also need the cats becasue my test pipes are causing problems so they should offer me a deal or i might consider getting total refund and go another route.

 

well i finally got through to kinetix and the best they could do is give them both for the package price. i got to figure out whether to stay with the stillen or the high flows. depending on wheter i get my ses problem fixed tomorrow i then will decide i guess. i just wish they would give them for like half price or something for the trouble. i mean i was honest and didnt just claim not gotton the plenum yet.

 

- They waive the core charge if you promise to ship your stock plenum asap

- You can buy the custom strut bar...it's not that expensive

- You can choose a color for your plenum

- It's made of metal...in fact, it's just a stock plenum re-worked, so you know it's quality.

The only reason I can think of to keep the stock plenum would be in case your kinetix cracked...which is not an issue with the Crawford.

Oh, and they also send you the right part when you order!

I still don't understand why people don't just buck up and pay a little extra for a quality product.

I have kinetix test pipes and I love them, but they took forever to show up and I was left in the dark as to the status of my order...but they had no problem charging my credit card right away. I don't think I'll order from Kinetix again.

Crawford waits until they ship before they charge you...and you can actually get in touch with them! A much better overall experience. I'm so happy I didn't go with the V2 Kinetix plenum.

 

ill take those race pipes off you jimmy

You keep talkin' about warranty work. Are you going to pull your plenum off an on every time you bring it to the dealer? My dealer is not mod friendly at all. He knows I have a plenum, and I've had no issues. Every time I bring my car to the dealer, which is not very often, all the salesman come out to look at my "G", because it's different in looks, sound and performance. Do you really think you can hide a mod like that from a dealer? My Crawford is on to stay!

well if my problem isn't bad o2 sensors, which i'll find out tomorrow, i'll be glad to sell them to you. but if all i need is new sensors than i'll probably keep them cause i love the gains. if i get rid of them you'll be the first on my list and i'll give them to you for cheap plus they are wrapped(if you care lol) only if you help me with my plenum. lol

 

good for you lou.

what if you have some serious engine problems and bring it in with the Crawford on it. Then they might not overlook it and say "that is the reason for your problem"

then of course, you foot the bill. may not happen but it is a possibility. if i have any serious problems I would spend the time and switch it out just so they cannot blame that for the failure.

i do understand your desire to talk up the crawford. seems like a great product. I, for one, have had the Kinetix plenum over six months now and just last week switched over from the version one to the version 4. I had not one problem with the version one until i spotted a small hairline crack at one of the center mounts. The version 4 has no center mounts and is much more solid than the 1st. It even feels better on the car than version 1 did when running it hard, and that I thought would be hard. Overall the gains are very good and if/when it cracks again I will get either get the newest version or just ask for my money back.

The swap took me less than one hour. i can live with that.

 

Just some FYI...

Our local dealer recommends 350z customers to Crawfords for all their performance needs.

More so, several dealers on this board push the product to their customers as a NICE performance option which won't void their warranty.



Go fast have fun!

 

I was talking about the extra charge to keep your stock plenum. With the KINETIX, it's no extra charge.

Once again, more charges for things that you don't have to buy with the KINETIX. PLUS, the Crawford strut bar is pretty fugly.

You can paint your KINETIX too. I guess this one is a tie.

+1 for Crawford. Metal IS better

How about trading in the car at the end of the lease and returning it to stock? Orrrrrr.... selling the car and taking off the performance parts to sell seperately. Or, as was mentioned before, if you have a problem and you want to put the stock plenum back on to avoid the plenum being blamed for the issue.

+1 for Crawford. It would be +5 if you could actually pick the parts up from Crawford. It always bugged me that I couldn't just go to KINETIX to ppick up the part I bought even though I lived about 4 miles from their shop.

Because it's not only more money, but you are giving up parts for your car that you don't have to with the KINETIX.

Let's do the math...

Crawford V5 plenum = $595 (keeping stock plenum)
Crawford Strut Bar = $175
-------------------------------------------
TOTAL = $770

KINETIX V4 Plenum = $399
KINETIX strut bar... oh, that's right. You can use your stock one = $0
-------------------------------------------
TOTAL = $399

Difference = $371 More for the Crawford

That's not a little more... that's A LOT more!

 

well i found out that my o2 sensors are fine so it is just the stillens causing the problem. what i think is they work on the '03 and not the '04(in the case of the ses light). so i am installing the high flows from kinetix now and i hope they are better. also i just payed the package price for them and im gonna get the plenum shipped 2 day by air for the regular price. not that bad of a deal i guess.

 

-Gotcha..didn't realize you wanted to keep the stock plenum. Let me say this : It's a bunch of crap "Oh, when my lease is up, I need the stock part, blah blah". I've leased several cars, modded the crap out of them, and NEVER had a problem trading them in. Dealerships love it because they get free mods.
Secondly, they wouldn't know there was a aftermarket plenum on the car if it slapped in the face when they opened the hood.
Thirdly, you could EASILY sell/trade for a stock plenum in the classifieds section. I garuntee a crawford wouldn't last 3 hours in there for the right price.

-Fugly? Ok...to each his own. Personally I drive with my hood closed and could give a crap what my engine looks like, as long as it looks like and engine and is color matched nicely...metal is metal.

-The crawford COMES painted in a color of your choice from the factory. So, yes, you can paint anything if you want to..that wasn't my point.

-WHICH IS THE MAIN REASON you should buy a plenum in the first place! I mean come on, what are we talking about here guys? REALIABLE HORSEPOWER. KEY WORD IS RELIABLE. If you made a plenum out of cardboard that made the same horsepower but cost half the price, would you put it on your car? Sounds like some of you would!

-If my engine had a "major malfunction" that could be attributed to the plenum (which is nearly impossible, unless you're running a kinetix and suck a piece of plastic into your cylinder...which is why it's good you guys keep the stock one...) I would simply ask to swap one of my local buddies for their stock Z plenum till my car was fixed or ask for help on the forum...or worst case, sell my crawford for $$+ stock plenum. Not a big deal.

Take out the core charge like I did, and you're looking at $175 for the crossbar. So while I'm "out" $371 in my pocket, according to you, you guys can keep looking under your hoods every two weeks for the dreaded "crack" and then post about it on this sight.

There should be no more "My kinetix crapped out, what do I do posts..." I think it's been covered! Anyone who buys a kinetix plenum should be fully aware of the risk they're taking. End of story. They should also be well aware with the warehouse issues and shipping time.


Here's a picture of my FUGLY engine bay!

 

If you're so happy with them then stop posting about your damn problems! DEAL WITH IT.

Plenum envy?

 

For what it is worth, my Kinetix hi-flows never kicked a CEL or SES light.
