cold air or short ram? What benefits does this mod give?

Here's what i'm looking at, for 2000 maxima,

Cold Air: http://www.cardomain.com/item/INJRD1935P
Short Ram: http://www.sportcompactonly.com/prod...=2129&c=99&l=2

 

It will sound better (If you like a bit more growl). And increased HP due to better air flow to engine. I'd just do ebay though. No point in spending so much for an item that will do the same as the ones on there.

 

Get a quality filter like an Apex'i filter, I'd go with either a Berk or Frankencar. Most of the 5th gens have those intakes....like me

 

For the 4th gen based I30 id go with an ebay intake but for the 5th gen based I30/35 id go for a more well proven design just my own .02

 

Ive personall had the injen intake it sucked nuttin but hot air from my radiator (not my fault poor design) and i hated it. If I were u I wouldnt even bother with it unless you were entering in a show or somehting. If you really want a cold air get a cattman not injen if you want a short ram get a wepon R but with a K&N filter you will love the sound and metal is metal on let anyone else tell you other wise saying the design of the wepon R doesnt cool air or watever ok. jyst my opinion

 

Berk looks good http://www.berktechnology.com/intakes.html one for 117$ I'm planning on installing it myself, how hard is it? If there are any manuals or necessary modifications that will be need (for exception of air box removal) please let me know. Thanks once again!

 

Installation is simple, remove old airbox and put in new.

 

, that's what i thought

 

Is paying extra $$ for Apex'i worth it? Or k/n is alright? K/N i assume stands for K&N brand???

 

This made the decision for me:

intresting read..... any other oppinions?

 

Yeah...like, slightly bogus!

"The most minute restriction in the air induction system will cause an engine's optimum power output to drop."

Our highly sophisticated engine management systems can compensate for minor restrictions in air flow with the net result being no such loss of "optimum power."

In other words, you will be hard-pressed to find a dyno test to confirm that a minute restriction will drop the power output!!

In many cases, stock intakes do as well as CAI's. Why? Becaused it's not the amount (aka, velocity) of air flow that makes the difference but the density of the air flow.

CAI's work by decreasing air intake temperature which increases density.

If a "restrictive" air filter causes a loss of power, it is not because it is letting in less air, it is because of the heat generated by the friction of air molecules against the air element.

In other words, you can have two air filters which let in identical volumes of air, but the one that causes the air temp to rise higher than the other will provide less power.

That is why punching holes in a stock intake is counterintuitive because it lets more hot air in than a closed system.

I also have issues with this statement about Apexi:

"Maintenance is kept to a minimum as this filter is a dry-type air filter and will alleviate the problem of filter oil from "wet" air cleaners, interfering with the air-flow meter."

While it is true that over-oiling a K&N filter can possibly muck up a MAF, if you do it properly, you will never get any oil being transferred to the inside.

Which brings me to the following question:

Did they use brand-new filters straight from the box?

The article never said so.

Also, you will never get anything near the air flow produced by a vacuum cleaner on the open road.

A more accurate test would have been to run them on identical cars driving on a dirt road for 500 miles.

 

Keep in mind the article was written by Supra owners for Supra owners. Although not too different, I would think a turbo engine responds more to a less restrictive intake and will indeed produce slightly less power with more restrictions.

 

so ignoring the article and going with short ram, will make a difference or should I spend that money on speeding tickets ?

 

I have a big hole in my stock airbox and gained almost 10whp.

 

I was diapointed with the quality of the cheapest one I bought on E-bay, the maf adaptor wouldn't fully seat and provide a good seal unless it was overtightened, which caused it to crack after awhile, try to find one with a aluminum maf adaptor if you can. Oh and DEFINITLY do it, it's worth it for the growl alone and it definitly gives more power also.

 

Thanks.

 

GAB = ~ 10whp on 3.5L ..

 

any pics?.. What's GAB?

gab is a big hole in your airbox..
ghetto airbox

 

What are you basing the 10whp increase off of? Gut feeling or Dyno?

 

3 dynos ...

 

no intake..trust me...sounds kinda cool..but thats it...

 

Yeah just get gab

 

Ok, so Apex'i is maintenance free. What's about K&N, it says something about oiling, ect... I don't really feel spending extra 60$$ on Apex'i just because K&N needs a cleaning every 30K

 

Well, the only drawback for K&N is that when people re-oil them and put too much oil which messes up the MAF.

 

what actually goes in to the re-oiling process and how is it done?

 

Google is helpful at times like this

lol, thanks i did a search too, after i posted.

 

My intake have me 170whp

 

Yes, but it has this nasty habit of whining...

 

i have a ram air and at idle all you hear is it sucking in air and then from like 1500-2200 it sounds like a truck at idle when they go vrrrrump vrrrrump reallyfast though. then above that it just sounds like a ******* jet engine (thast what my dad said when i pulled outta the neighorhood) but now since its snowing where i live i bet my engine is having a blast just sucking in hella cold air. you can tell the torque difference too from hot to cold air. but its also 5 degrees here.
