Best performing CAI for the 4th Gen?
What do you think is the best performing CAI for the 4th gens?
I remember reading something on here about PR receiving the coolest air, but can't find the thread any longer, and wanted to get a general consensus on performance... So, what do you think? Please vote and add any comments you have
Cheers

i have the place racing style now and is much better in my opinion than any other i have had the popcharger and it really robs the low end so with this it is great and amzing power on low end compared to the other setup -but u do have to drill a 3inch hole in your car but yea i would def go with pr

Any particular reason?
P.S. Wanna sell the PR?

was thinking of getting the injen just because of placement of the filter, would think it would get colder air. Maybe i am wrong. I have issues with cutting a 3" hole in my car.

So you wanna sell the PR?

Not any colder than the PR, plus the PR is cold all the time. So I don't know what the advantage is. Especially when it's going to gulp down a chunk of hot air everytime you are at a stop.

dont forget that the injen is CARB approved.

dude why dont you just got short ram?
on deciding on intake type, you have to go with your knowledge... by that, i mean you have to layout where the filter will sit, and what you think will be more beneficial in power... unless someone has a dyno, which i have yet to see one then this will never end...
i have a few links you should read on my site: maxima.accessjdm.com/threads.php
i've looked at your flash page so i guess your into computers... please disregard the css coding if it does not display right in your browser... i am working on fixing it now!

I like my Injen. I installed a larger filter because the one that comes with it is so small.

Has anybody done any dyno testing of these intakes in the same car? I'd like to see some numbers. I have the injen intake but I would assume the PR has to provide colder air and therefore more power. I can't imagine the difference to be that big though, prob immaterial.

I have the injen and I love it. I was going to go with the PR but what I assumed was that if the car is dropped, wont it hit the filter. And isnt it easier for water to get up in the filter leading to hydro lock?

I do UL (Underwriter's Laboratories) experiments every once in a while at work. And so I had the brilliant idea to bring some of the test equipment into my car. Specifically, the thermal couples that are used to measure temperature at specific points. There's a hot (excuse the pun) debate on whether the Injen CAI, Placeracing CAI, and popchargers really take in different temperatures of air in the engine bay. So I decided to wire up some thermal couples and drive around. The results are quite interesting...
Probe #1
I placed one right behind the driver's side foglight bay (I don't have any foglights, so it's straight ram air). This would be pretty close to where the place racing CAI would be, except in the wheel well and not directly exposed.
Probe #2
I had another thermalcouple taped to the filter of my Injen CAI, this intake sits right behind the radiator (not the best place, but the only place if you don't want to cut holes)
Probe #3
And one more was placed where your favorite WAI would normally go.
Probe #4
As a control, I had one located outside of the engine bay for ambient temperatures. It's was cloudy/scattered showers in Dallas, Texas at about 65F.
Fired up the engine and went for a little drive. I drove three different stlyes: Normal start/stop traffic, aggressive WOT, and cruising on the highway. Turning A/C off or on made no difference at all. Results?
Probe #1 kept at a VERY steady 65 degrees, I figured it would be actually colder with all that wind. But I guess that's windchill not temperature.
Probe #2 Was the HOTTEST out of all the the sensors. Sitting behind the radiator the probe would read anywhere from 90 degrees up to 130 degrees. At idle, or at a stop light, it would increase a slight 5 degrees and settle because the radiator fan would kick in.
Probe #3 the big surprise... This probe had the most fluctuations. At idle or at a stop light it would heat up to the same temp as the probe #2 (the CAI). Sometimes it would be hotter, but most of the time it was the same temp. But the interesting thing is that when I was driving and cruising, the temperature would drop to about 10 degrees above ambient (so mid 70s) so actually it would be about 20-30 degrees COOLER than the COLD AIR INTAKE.
This kind of data made some interesting conclusions. And I guess you can draw your own or discuss on this thread... I think from a standstill, the Cold Air might have a slight advantage since the engine bay heats up. But from a cruising speed, it sure does look like the WAI has the cooler air flowing into the engine. The best would place for the intake would probably right at the fog light, where there's plenty of cold air flowing there, however it's more susceptible to water entering.
What do you guys think?

This again?
The ebay place racing CAI style is the best!
The only competition is between the Short Ram/HAI/PC CAI
The Injen looks better but is in the WORST place, basicly touching exhaust pipes and the radiator.
