from some of the posts I've seen, people think that Ingen will suck in cold air because the filter is sitting behind the radiator.

Someone said that when the radiator fan starts spinning it will have the same effect as a PR Cai because the fan is drawing in air from the outside

Do you all have any idea how hot it is behind the raidator?

ESPECIALLY when the fan is blowing?

The air from the fan is the air that passed through the HEAT EXCHANGER!!

Open the hood up and stick your hand in behind the radiator WHEN the fan is blowing.. See hot the air is

 

plus isn't the inlet is situated very close to the "hot" tranny

 

like I've said before, someone needs to stick a thermometer at close to the air entering the TB as possible. Then we'll have data.

 

Injen = all looks and minimal gains

PR CAI = better looking, IMHO, and operates much cooler

one advantage of Injen is no cutting though...thats good for guys who don't plan on keeping their car forever!

 

aaa


NO..

 

people who have the injen think its better. people who have PR think its better. people who have frankencar thinks its better.

 

Only PR will suck in air from outside the engine bay...

 

not true

try again

 

thank you..

 

They all suck.

 

Injen is not a true Cold Air Intake..

 

Your stock airbox is the best CAI you will find. Notice is sucks air in from the grill but above the radiator? These engineers aren't idiots.

 

And when it's not cold outside none of them are.

 

judging from the fact the black plastic from spare tire well is gone.. your theory is wrong

 

Yea but it can be 90 degrees outside and a true CAI will still be sucking in cooler air then an engine bay...

 

Is 90º air classified as COLD air?


umm no....

 

Well your right there, so we will call it a "cooler" air intake then

 

 

 

and people using the intake setup from a '95 Eclipse will think theres is better as well!

 

 

My thoughts exactly.

 

At least spell it right dude.

 

It's also the most restrictive. You can get a bucket full of cold air, but if you run it thru the stock air box, you'll only get out a cup full. Nissan engineers were not the first to think about getting air from a cooler source, racers were. They may not be idiots, just bad copycats.

 

No need for a thermometer, since any OBD-II scan tool measures and records your intake air temperature(IAT) sensor readings.

I don't think taking a measurement as close as possible to the TB really matters.

 

yeh dont u think the people who built our cars know about this stuff? in my opinion, the stock air box works very well. my sisters 92 max has a lot more jump down in lower end. i think those filter intakes add a little imaginary hp if u ask me.

 

they know about it but that doesnt mean they are going to use their knowledge. car companies go for the quiter route with a little less HP than to go the noisier route with a little more HP because most people dont want a loud car.

check out a dyno. it will show you for sure how much "imaginary" hp you are gaining.

 

Anyone who has installed an Injen on their 2k2 knows that there is no question there is power gain from 4000 rpm up. And the air filter actually sits below the radiator. Not directly in the path of the air. Airflow through the VQ engine bay is very good. AFter getting home from work the other night when it was 47 degrees, my Injen pipe was cool to the touch and so was the intake manifold. Plus if you wrap your intake with header wrap or other insulator, you don't have to worry about the pipe being "next to the hot tranny".

at least someone agrees with me and deezo. obviously i'm biased i won't lie. but Deezo was saying all this on sunday. radiator=hot, bends=bad

 

...and not saying that there isn't a gain from using it, but where is it getting its cold air from?

 

Hey now.. my ***** bends and the ladies say its very effective when the times get hot

 

Damn that's bad. Hope its only one curve because if you had 2, I'd say you need surgery.

 

 

OT but is that frankenmans car in your sig along with yours?

 

 

 

 

This thread is pointless and a half. Do a search on the CAI versus hybrid.
