want some input/ I'm stuck

[AZFAIRLADYZ]

ok well first off i am stuck in choosing between two intake systems. Both are from Injen. One is the cold air intake system, and the other is a new short ram intake. I know there are threads about intakes. Not to many on the new HR. So I'm just looking for some help. Here's the link's for both

if anyone has any experience with these or any experience with a short ram or cold air intakes in general. I would like to hear your input.

Thanks

I've got the HR as well and have been doing a lot of googling to see what's out there for this motor.

Apparently just replacing our stock paper filters with some K&N's may be the best way to go. I'm picking some up soon and will let you know if anything different is noticeable (performance-wise).

I was going to do Nismo CAI, then looked into the Injens and JWT pop, but from all that I've read on this and some other forums, they have more of a pronounced affect on the 03-05 DE motors, and our HR's don't get the same result from a new intake. I also read something today about one guy's CAI's taking on water and sputtering the engine to a halt, so you may want to just go short ram...his engine didn't lock up or anything, and he was able to dry the filters out, but it was a scary hassle.

Maybe someone has experience otherwise? I'm going to wait to lay out the cash for a CAI or short until I try the simple K&N drop-ins and see what they do.

I think the general idea is that the HRs dual intake is almost perfect for it. changing the filters to a higher flowing element would not only give you a little bit of a gain but be rather expensive. (two K&N filters @ $50 a pop)

I have the Nismo CAI for my HR. The Nismo CAi does not extend down to the bumper like the one you have in pic. 3.

My only concern with the CAI from injen is that it does not look like it has a bypass valve. This could be a problem when it rains as it could suck up water. The short tubes should be cheaper and cause less problems. If you do go with the CAI make sure you buy some bypass valves.

ex. bypass valves-it will save your engine

my vote...short tubes.

these are the Nismo CAI, just like mine.

Goodluck and Happy Modding!!!

the only time u need a bypass valve is if u drive threw a deep puddle and submerge the filter. i say injen cai

Do you have an aftermarket airfilter installed in your Z? If not, please refrain from posting.

Bypass valves are cheaper than having to repair your engine from hydro lock. If you do go for the long tube intake, please remember that you have to service your airfilter. It would be a PITA to have to take out your bumper just to service your airfilter.

Either way, let us know what you think of the Injen Intakes. You will love the sound!

I had the long tube Nismo CAI. I had to remove the bumper to get that piece out, not to mention it was stuffed in there and always got dirty from the vents in the wheel well. I have a DE though so the piping/bodywork may be different.

EDIT: the only time you need a spare tire...is when you need a spare tire

[R350Zz33]

why does it matter if i have a after market intake to post here i know alot about intakes for the z and other cars so why would i not give my input. everyone deserves there opinion

Because you don't know what you are talking about. Most of your "knowledge" comes from YouTube, he said/ she said, and something you read, that can't be proven. We want FACTS here.

Honestly, STFU! nobody likes you here, we can't trust what you say!

if anyone has any experience with these or any experience with a short ram or cold air intakes in general. I would like to hear your input.Thanks

You have no experience, so you have no input. Sorry to mess up your thread OP.

I have the same intake. I just took it off a couple of weeks ago because it's been raining more here in cali. Our freeways over here aren't designed for heavy rain, therefore lack adequate storm drains. When it rains significantly, there are puddles of water everywhere, making CAI's vulnerable to sucking up water. The DE's nismo cone sits right next to the vents in the wheel well. That area gets soaked in the rain. So I take it off during rain season and put it back on during the spring/summer. Yes, it came with a bypass valve. I'd rather be safe than sorry. Hydrolock is not covered by my warranty (they can link it with CAI installation).

There is a easier alternative to taking the whole bumper off. With everthing unbolted and clamps loose: 1) Jack the car up (front side only). 2) Turn the wheel max clockwise. Remove plastic liner from inside the wheel well. 3) Turn the cone so that it's width fits the clearance between the tire and the front bumper/fender and rest should slide right out.

Another one that i haven't tried yet (which also seems a lot easier) is to jack the car up, remove the plastic cover from under the bumper (driver side, where the lower half of the intake is located) and (theoretically) the cone and bottom assembly should just drop right down.

haha it's ok. I've read alot of threads on here, but that aside. I do have K&N drop-ins for my Z. I've notice a slight performance increase, as well as MPG. I like them, but i do want to upgrade my intake and exhaust. I am a fan of TD, and titanium tip . So I'm looking at Injen TD, or HKS Hi power.

Also thanks xjmxstac for the info! That will help.

There is a FAQ about short ram vs. CAIMy gripe about CAI is practicality. We all know that the filter has to be cleaned every so often. With a CAI (mine's a DE so it might be different) it's a PITA to service. You need to jack the car up just to get to the cone filter. As I can imagine, Arizona doesn't see as much rain as we do in cali, so i don't think you'd have issues with hydrolock.

[rmezz13]

i honestly like working on my car (pride thing) so i don't mind taking off the plastic underneath the car to service the air filter. Yeah it can be called a PITA but its worth the outcome...

[Anthonysflying]

ah yes that convenient little corner shield...mine isn't coming off unless i cut it out. one of those 10mm bolts got stuck in one of those metal clips that secures the plastic.

Well I have a single intake '06 Z. But 2 of my buddies have the '07's and each has a different intake system on it. One is a Nismo and the other is a Fujita. I have to say from experience that i like the Fujita more. Even through Nismo stuff is great, I know I have a few, the Fujita's look better, sound better and maybe its my imagination but they seem to provide more power. Plus, they are cheaper, and if you can get a product thats cheaper and preforms better then it becomes a no brainer. I also have a connect that can get them even cheaper then ebay or anywhere else. Let me know if you interested.

I was referring to the entire covering underneath... i have the injen CAI, filter sets in front of the radiator, just right (or left) of center (depending on if you call it from looking at the front or from inside the car looking forward).

...it's probably the sound that's making it seem that the Fujita produces more power. Unless you have a very sensitive behind that you can tell a difference of 3hp on a 300hp engine.

The Fujita is shiny!

the Fujita is shiny, at first thats what i was going towards. After doing some more research and lots of reading, I found myself being drawn towards the injen. Well right now I am currently moved to Alaska(military). so I am looking to order, since no one up here carries Injen(only AEM) I guess I'll order direct.

[AZFAIRLADYZ]

thank you sir hmmm... I was wondering if injectedperformance might be able to help me out....

[DeepBlueHR]

I have the Stillen short tube intakes on my 07 Z. I painted the heat boxes to match the car. Stillen is getting ready to release their ultra long tube intakes where the filters sit infront of the radiator toward the top, so hydro locking should not be a concern. Stillen makes three different lenghts of intakes for the HR. Just another intake to consider. http://www.stillen.com

[AZFAIRLADYZ]

really? I thought thier ultra long tube was on for the Infiniti's with the HR motor. The only reason i say this is because of the grill, since Z's don't have one in the same spot. what color did you pant the heat boxes? can you post a pic or two?

[ldstang50]

I just purchased the K&N drop in filters. I wanted more intake flow but the cone filters and tubing replacement is illegal in stock class.Filters should be here next week. I'll be putting them on at the same time as I put on my Stillen true dual catback.I dont' expect much gains, but I'll tell you what the butt dyno says.....Wait this could be a good opportunity to try out the pocket dyno on my dad's iphone

[350z_drift]

i would go the second one

[phyzicxz]

go with a nismo cold air intake ;]

[R350Zz33]

why the nismo one the injen's are better there cold air intake for the hr's are the only real cai
