Cold Air Intake

[biggee247]

I am about to purchase a cold air intake.

I understand there are 2 different kinds.

1) Standard cold air intake.2) Ram Air Intake

What are the main differences between the two. When i think of ram air, i just wonder where is the MAF sensor going to go, because all the piping seems smaller. So where would it go.

Which one is honestly better. I just plan to go exhaust, header, and intake. Just need help in determing which one would add the most horsepower and easiest install. Not worried about cost.

1993 240sx is what i have.

You have a short ram , and a long ram (cold air).

Short ram has a short pipe and the filter sits in your engine bay. A Cold air has a longer pipe and the air filter sits in front of your left front tire in your wheel well.

IMO , short ram is the way to go , because long air is a pain is the *** when you want to clean your filter.

Short Ram



Cold Air (except it would be in front of your left front tire)

Also with long intake, there is a possibility of sucking water into ur engine if u drive in deep water or in puddles!

Wich is called Hydro lock.

.........why in the hell would you drive your car into deep water? The cold air intakes won't ever take in nearly enough water for hydro lock.

Your source please?

[redtop91]

Using CAI's for years in Oklahoma winters and in Seattle for weeks is my source. Won't happen, provided, that you have a filter that isn't crap like the HKS or Greddy ones and you don't submerge the intake in water..

[Ptownsound]

if you plan on driving in deep water theres an intake that travels up to your roof. but thats just if you live in Oregon or Washington.

Q: When should I use an Air Bypass Valve?

A: The AEM Bypass Valve protects the engine from ingesting water and hydro-locking if the filter becomes submerged in water. Hydro locking occurs when the end of the inlet pipe is submerged in water and the water is sucked into the engine. Driving the vehicle in rainy conditions is not enough to cause a problem unless the vehicle submerges enough that the inlet end of the pipe is immersed in water. Rain impingement on the filter will not cause a hydro lock condition.

The distance of the filter from the road dictates the level of water that can cause damage. This distance varies with the vehicle ride height, which is why there are no published numbers for this measurement. We suggest taking this measurement and keeping it in a log book, so that in the event you encounter deep water you will know what your maximum allowable depth is before potential submersion of the inlet pipe.

All AEM Cold Air Intake installations retain the factory splash shield (fender liner) for filter protection and performance. Removal of splash shield actually deteriorates performance by allowing air heated by the pavement to enter the filter and negates any positive pressure created in the air filter area when the vehicle is in motion.

There are some instances where there is not enough room around the inlet pipe for adequate clearance of an Air Bypass Valve. In these instances, we recommend installing a Short Ram system if water ingestion is a concern.

Looks like your right.

Like I said, don't submerge the intake which is common knowledge and it will be fine.

A heat shield in the engine bay would be a better way to go than extending the intake pipe.

Come to South Florida when it's Hurricane season...plenty of deep water here!

Okay so pretty much short ram is the way to go. Judging by research long ram is better because it get's colder air rushed into it, but it really wouldnt make a big difference.

I believe ill go short ram.

What is the best intake to buy w/filter. Im looking for short ram air, w/great filter. Cost isnt an option at the moment? Like a reputable dealer online.

Better yet have the short intake then make a box made of aluminum to channel cold air into the filter and block it off from the exhaust... no hydrolock and a cold air intake... Slappy is right, getting to the filter sucks for cold air intakes

Yeah same on, just mine is 50 cents cheaper, lol, it's all about bargaining baby!

[Slappy]

Well , like i said in the other thread, its just a hollow pipe with a filter.

People claim 15hp+ gains but in real life its more like 5-7hp.

[xekushnr]

The main gain will be a slightly increased throttle response and you will hear your car sucking in air at WOT. It wont be much faster, but it will feel faster.

I never understood how come these intakes are so expensive. If you guys took some initiative you could have made your own for less than $40. I bought two intakes from ebay (for different cars) and did a little cutting and fitting ..had a cold air intake for less than $25. ;x

[Slappy]

I didnt pay that price years back when i bought my Injen , its just the prices have went up alot since then. But i see your point.

[CMG]

Years ago I had an Injen intake that I got for free with a lot of parts. It was on a ka24e. The intake and exhaust and stripping made a huge difference in the car. The Injen intake will last a long time and at least they have some R&D on it. Only reason I would buy an injen nowadays is if for some reason I wanted to get an intake that was carb certified.

Go short ram. No doubt about it.

amen brother. e-bay piping, just buy a high flow filter. saving money ftw.
