I own a 07' hemi and I am stuck on which cold air intake (CAI) to purchase. I have heard good and bad about all brands. I was thinking of doing a Mopar setup but I dont have enough information to buy one yet. I want all the power. Anyone have a CAI? Im probably one of the more analytical people here and also a college student (could use some cash). In other words, I read a LOT before I buy and always want the absolute most bang for my buck. Any help would be great, thanks

 

Plenty of info here: https://dodgeforum.com/m_1069155/tm.htm the search function works well too.

 

Hey man, I have a True Flow for sale. It's on my 06 but it will fit an 07 as well. It comes with a filter cleaning kit too. If you read through some threads you will see it is a very common intake on this forum. Private message me if you are interested, if not, good luck in your quest.

 

i have a K&N CAI on my 05 hemi

it really woke it up
first upgrade actually

 

Search! There are a ton of threads on this topic.

To get you started though....K&N and Truflow seem to be the most popular. I have a S&B on mine, it was the best price, really improved throttle response.

 

it is a very sound idea
to 'read a lot' before buying a CAI

these 3 links should be read over more than once:

your Ram has an even larger and less restrictive air filter
than the smaller LX 300 factory air boxes tested here
...but notice that the CAIs don't even show a gain against smaller airboxes:

a test on diesel Rams by 'honestly' testing a new paper filter against the claims of the aftermarket CAI...unlike the typical 'trick' of running the paper filter on dusty roads until it is highly resticted and then testing fresh new CAIs against it.

if you do 'a lot of reading' on the weblinks above
you will understand why
the Toyota 5.7 V8 does not have a CAI from the factory
even though it was designed to win a 'horsepower war'
against other truck engines like the 5.7 Hemi
and also why
the newly announced model year 2009 5.7 Hemi
has a long list of improvements & mods
...but still no CAI

Don't join the suckers...do mods that work....and spend money effectively

 

I am convinced that the Factory air intake is just fine. It keeps the most dirt out of the engine, as shown in several of the partical capture tests, and the horsepower difference by 2+/- rwhp proves to me the aftermarket CAI's are not only a waste of money, but a rick to the engine as they showed they allowed more dirt into the engine than the factoryfilter. Thisdefeats any benefits of 2+/- rwhp.

Like one guy whoin the test who was once swayedby the hype of having a K&N, said: "I'll stick a Mopar Sticker on my Factory Air Intake and call it a day..."

 

i def noticed a difference in power with my CAI and you cant deny the beautiful sound when you open it up. do your research and you'll find that the mopar intake is actually a AEM brute force (which is what i have) that has a mopar sticker on it. AEM, from what i've seen, seems to be the best bang for the buck and the most popular on the forums

 

FS, I'm sure the sound is different, but after reviewing actual tests, I am not convinced the gain in HP is worth the dollar spent. The tests I've read show an average before & after DYNO RWHP of 2 +/-. While some may feel that is a worthy difference for the money spent, the real turn off for me of the aftermarket filters was the significantly higher measured particles that passed throught the aftermarket CAI's and into the engine.

I'm not faulting anyone who spends their own money on these aftermarket CAI's for a small HP gain and/or sound, but the actual testing has convinced me to stay with the stock air intake.

 

i shouldve stated before that the CAI was the last of the upgrades i did. I aslo have full exhaust and 4.10 gears. Once you start upping the amount of horsepower your truck has, you'll notice more of a gain from the CAI than without any other upgrades
