which is better?

i dont mind spending 260 for a new cai, found both around the same price..

but just saw a post for a guy selling a used injen cai for 150 obo.. used for a few months, less than 1k miles on it... worth it?

or if u guys think cai arent really worth it at all, please do suggest something else in the price range.. im going to be getting motordyne spacers (12-14hp increase) for 280 later as well, but other than that, im not sure what else to get for under 300

 

look into the JWT popcharger...

 

none of em really do anything, but it's fun to install and start learning more about your car.

 

yeah i read some more on them and saw they dont do much but sound good, and injen seems to be the winner in sound

what about the jwt popcharger mentioned above? i looked it up and states ~6rhp increase... would i need the tube or just the heatshield & filter? thatd only run me 115, so id be happy with that for sure if its more worth it than the cai

 

AEM is vastly superior interms of quality. Injen **** always falls appart. I have an AEM one and love it and it has a bypass valve which eliminates any potential hydro lock. The CAI is worth it. The short ram setup like the stillen and jwt poop charger are definitely not.

 

the poop charger is for sound not performance.

 

Before and after dyno proof?

 

WRONG.

 

I went with the K&N 57-6013, http://www.knfilters.com/news/news.aspx?ID=378 ,for two reasons. 1. Name 2. It’s made from plastic and not metal so it doesn't heat up. One more reason, not that many people on this site seem to think much of it and a lot do not have. So I wanted to be different. I have been happy with it. I did notice a little difference. Noise wise, it doesn't really make anything louder. You can hear throttle body a little better though.

 

Thats funny, I've heard of some people switching to SR from CAI and getting better times and traps. Who woulda thunk it.

 

pop chargers sound very good, couldnt tell you much about the performance gains though...

 

well, didnt i just start a little ruckus..

so now its more like short ram vs cai...

 

It's personal preference. There isn't much documentation on the actual power gain differences between the two types and Im sure it's minimal at most. The overall gains of ALL of them are minimal. Personally, I have the AEM (w/bypass valve) and will be getting rid of it shortly (for FI). I wasn't aware of the JWT when I got my AEM back in 2003 and have thought about going JWT instead just to see what it's like. JWT pop charger is a good piece and a forum favorite from what it seems, especially for the price.

 

itd save me $60, atleast on ebay, to get the pop charger combo with tube... so, its a nice savings especially when i know itll all add up in the end.. if the difference is minimal (power-wise) then i may go with that... know any vendors on here or g35driver that has them for cheap?

 

From what I remember Performance Nissan has the best price. In the end they're all within like $10-20.

You like to post misinformation dont you? Didnt you learn your lesson from this thread (post #84 on) https://my350z.com/forum/tuning/268925-got-my-06-tuned-3.html

I said it once, I'll say it again, I have dyno and track tested an AEM vs Pop-charger back like 3 years ago and found the CAI to suck nothing but serious a$$. See my reply to you in the thread above for more info. Ive had an AEM, and a PC, the AEM is garbage, and dont get me started on that silly bypass valve they would lead newbs to believe can trap anything let alone water

AEM/CAI's are for suckers, enjoy your intake whistle while stock Z's blow by you

 

OP-go with a short ram of your choice, CAI's dont work well with our cars, switching from my AEM to PC yielded 10whp with no tuning, same dyno, correction, etc, and its easier to keep clean, and to service. And you dont have to run a gay bypass valve that doesnt do $hit anyway but block the airflow...

My GF (mid-a-mamma) knows more about intakes on Z's than this dude...

 

JWT popchargers are good bang for your buck. Like Driven said all intake gains are going to be minimal, why spend twice as much on one if you don't have too? Other then a spacer and popcharger I'd highly recommend swapping out your cats for test pipes. A set of used test pipes can be had for as little as $100, and the three mods should put you into M3 territory.
