Header, Intake, & Exhaust - Need help deciding...

I'm purchasing an Injen intake this week. Should I go with cold or short ram?? I can't decide...money isn't the issue.

I like the CAI, but I heard you only notice the gains when you're in the mid to high rpms. This true? With short ram I heard you notice gains during initial acceleration. Please provde insight on this.... I also live in Wisconsin...lots of snow and a decent amount of rain...CAI might become an issue for me. Has anyone had both installed on their cars, can you really tell a difference?

i can't emphasize enough the minimal amount of difference in gains between a cai and a sri. you will barely, BARELY notice the difference if you bought the two. one thing that'd be evident is a different tone (because one is longer/deeper), but other than that, you can just pick one.

here's how theory works: the cai is located in the bumper or somewhere where cold air is readily available; the sri is located in the engine bay, where air is warmer than the air that the cai is exposed to

here's what counters the theory: the cai will get the cooler air, but as it travels up the longer tube, it'll get heated slightly because it passes by the engine; the sri will have slightly better throttle response than a cai because the air will travel faster to the engine

each have their pros/cons. obviously if it snows a lot and you get a LOT of rain (eg. flooding of 1+ feet of rain) you do not want a cai. but if this isn't the case, then take your pick

So will I get a deeper sound with the CAI...just so I understand correctly?

pretty much the same thing. but yes deeper. the short ram just has more...umph? and sounds more agressive imo

Anyone have any sound clips of the two?

go on you tube and type it in, if snow and rain is the issue and you dont want to get hydrolock, you can get a bypass valve put on the cai but it might decrease gains that you will get, if anuything go with the sri its cheaper and a less chance of hydrolock

i would get the CAI (i have one) and water/snow is not an issue as long as it is not 1+FT (as my05civic said) but if your seriously worried about hydrolock, then buy the SRI. the difference between the 2 are about 1-2 HP. but like others have said above....choose one, i know with injen you will be happy.:)

or yoou can go with an ebay cai or sri and smack on a K and n filter, same difference

Thanks everyone...I'm probably gonna go with the Injen Short Ram...I'll post pics when it's installed

:)good choice!

I just spoke to an AEM guy about the different configurations. The biggest gains come from their V2 system which features a larger diameter transition length of tubing. So, yes, just extending a short ram to reach cold air is not always the best answer. Still, cold air can make a huge difference in performance, especially after sitting in traffic and having your engine bay temps exceed 140 degrees F. That'll weaken ANY engine, regardless of filter size. Here's more info on the V2:





V2 Intakes
FAQs...


AEM’s V2 intake systems use a patented dual chamber design that maximizes horsepower and torque - producing even more power that our own Cold Air systems.

On a dyno graph, the area under the power band (or power curve) represents the amount of effort that an engine is producing. The larger the overall area under the curve, the more power your engine is making. The AEM V2 utilizes a dual chamber (using two different diameters and lengths of piping) that creates multiple frequency sound waves to produce the largest area under the curve of any intake system on the market. These sound waves help charge the cylinders with more air throughout the entire rpm range and are what enables the V2 to outperform even our own Cold Air systems.

We have found that inlet length plays a vital role in the power production of V2 systems and not all V2 induction systems relocate the filter outside of the engine compartment. In these cases, we performed extensive temperature testing to locate the filter in the coolest area of the engine compartment to achieve the lowest inlet temperatures possible. Please refer to our temperature testing procedures for more information.

We EXTREMELY abused one of our Synthetic DRYFLOW Air Filters with brake cleaner, window cleaner, industrial cleaner, bleach, Honda Brite, carb cleaner, weld prep and topped it off by blowing the filter out from the inside with 125psi directed air stream... Then sent it back for independent testing to see how efficient the filter would be.

I'm not sure if these "Click Here"s work, but I like the attributes of the system. In fact, I'll be installing one in a few days.

AEM, and Injen or any other manufacturer, will say anything they can to toot their own horn...
