i just went to the local tuner shop and they gave me a quote on an injen intake for $309 (for part) and $380 total (for instal). if anyone here has injen and put it in themselves please respond and let me know if it was hard or easy. they said it was tough but idn if they were just trying to make some extra money or what. thanks for any help.

 

I don't have an Injen intake. But, that is a total ripoff do it yourself and put that extra money towards more mods. And it is a good learning experience if you do it yourself. I would even help you out if you lived near me.

Hear is a link to the install: http://www.overboost.com/story.asp?id=1085

 

intake's are easy....simple hand tools and detailed instructions...do it yourself man

 

It's not too bad. You have to remove the lower plastic shield (that covers the bottom of the engine), the OE intake, route the flexible portion of the Injen intake to the front of the grille, and attach an adapter to a portion of the bumper - took me about 2 hours.

 

unless you like it in the a$$, tell them to get off your back before you get raped. you should be able to get that intake for $250 new: http://www.hopupracing.com/noname1.html or less than that used on this forum. and that install quote is laughable. do it yourself, its not hard. however for an intake I'd recommend a JWT popcharger over the injen CAI, especially if you plan on getting a spacer.

 

where do you get the JWT popchargers cause i went on their site and doesnt look like you can order them from there

 

I have the Injen CAI. It's a very easy install, I would definitely advise you to do it yourself. You're not going to gain a whole lot of HP if any from either the Injen or JWT, so get what you think looks better. Good luck!

 

NEWB Question- Why wouldn't you gain anything from an intake??? I am thinking the same thing geting the Injen intake coupled with the Injen SES exhaust. i am just wondering if this statment is shared by others?

 

The stock intake is pretty good, gains for intakes are minimal compared to what you might get on a car with a poor intake. They do look and sound cool so there is other stuff to consider depending on your goals.

If I were you I would search search and search again before spending your money, both this intake and exhaust have been covered quite extensively here.

Hypersprite.....Thanx for the info. I have been reading and reading and then I read some more. That’s why I love this site, every one else’s trial and error is extremely invaluable especially for someone like me. With all that info, I am leaning towards the Injen set up rather than the Borla, K&N, ETC. I just thought perhaps I mised a post or something in regards to the power gains or just to get another point of view.

 

Hey Fear's Track 06:
Sorry didn't mean to Hijack your post. $380 installed that's BS. My B.I.L shop told me $245 installed..... $225 just for the part. I would do it myself but no time.

 

No time? It's an hour MAX for the install, if that's really the case, hell i'll do it for you. All i ask is a case of white castle and im good to go.

 

The statement is shared by other stock 350Z drivers and those who do not race. You will read time and time again:

Don't waste your money on a intake. The stock intake is just fine.

Don't waste your money on headers. Headers are expensive and provide little gain.

...and similar statements. Its up to you if you want to run, say, 13.9 seconds in a stock 350Z, or, as an example, 13.4 seconds in a modified 350Z. Decide if the cost and 0.5 seconds is worthwhile to you. On the street, 0.5 seconds is meaningless. At the 1/4 mile finish line, 0.5 seconds is like a lifetime.

 

So your saying $2200 in mods (rough estimate from your sig) and good tires will get you half a second?

I use to have the JWT pop charger and now I have the Injen CAI, not a noticeable difference. I installed both and the Injen is a little harder because you have to remove the bumper to have room to work, but 2 hours sounds about right on install time. Now my idle is not as stable as with the pop charger, it tends to be a bit lower at times and it knocks a bit. This seems to be a common occurence with the CAI. But it looks kick *** in comparison. Good luck.

With mods and tires and practice I knocked 0.70 seconds off my ET.

 

Well david I see your point, but some people like you seem to have done SIGNIFICANTLY more research than others.

The overall design for the K&N Typhoon, in my opinion, is simply a better design than any other intake out there for the 350Z.

Here is my subjective analysis:


Stock intake:

pro: sucks cold air, has low pressure losses, OEM paper filter is very good making this the cleanest intake for your engine

con: once you start flowing more air in general, stock intake box may start to have issues.

JWT popcharger:

pro: can suck higher volume of air compared to stock

con: sucks hot air and heat shield does not really prevent it from sucking hot air

Long tube CAI:

pro: sucks colder air, (note...so does stock)
con: more pressure losses due to a longer tube. this is a fact of life folks. more bends and longer tube = more pressure losses

K&N typhoon:

pro: sucks higher volume of air compared to stock. attempts to offset JWT popcharger's hot-air syndrome by incorporating a cold air scoop.

con: cannot think of any, except that the scoop may not be all that effective


Anyone have something to add, please be my guest

In summary, I am sticking with the stock intake. If I were to buy one, it would be the K&N typhoon.

 

Your analysis is detailed and on target as usual. My post about mods, cost and performance is more general than just the intake. And, as you mentioned, each intake has advantages and disadvantages.

 

good analysis if you dont mind some additions from some trial and error as from myself and others I have heard from

STOCK:
pros- no warranty issues or hassles if you get work done
cons- looks, sound and size

JWT POP:
pros- sounds better, provides better and quicker air flow over stock/CAI, will have a more noticable improvement in performance with addition of plenum spacer, heads, test pipes and exhaust over stock or CAI.
cons- little improvement over stock or CAI without extensive modifications.

CAI:
pros- sounds cool and looks cooler than previous intakes. Supposed to provide cooler air.
cons- While the CAI is supposed to suck in colder air the actual temperature difference is going to very small once your engine has warmed up. Reality is that your engine bay gets hot enough that most of the effects of sucking cooler air from the front bumper area area very nil once the air has to pass through the super heated pipes by your radiator and engine. last con on the CAI, if it gets wet and you dont have a bypass valve, you get a very wet, restrictive filter and lots of humid air coming into your engine.

K&N:
never used it but sticking with my modified Nismo CAI. Took off the down tubing, put the turn pipe and the filter directly on the MAF assembly and wala I have a short ram intake aka POP Charger.

Again this is in addition to the previous post about the pro's and cons to each. done wasting money on an intakes and my set up works great now with the headers, test pipes, exhaust and will soon be adding a thermal plenum spacer.
