This is a review of the AirRaid 301-237 Synthamax Dry CAI System.
Purchased from Autoanything.com for $334.71 (Phone price included shipping and no tax to Illinois)

Packaging:
Box arrived within one week of order. box was twice as big as the entire system but included excessive amounts of bubble wrap. A checklist of all the parts was included hand inspected and signed by the person performing assembly of the order.

Components came loose with the exception of the small screws and adapters which came in a sealed bag known as the hardware pack.

The filter came in its own marked retail box. The filter inside was shrink wrapped.

Directions:
The directions come on a double sided sheet with black and white pictures. The biggest confusion for me in terms of the direction was deducing between the reducers hose and the hump hose. But part numbers made it clear. Another issue is when installing the gasket at the end, the picture is difficult to see, but after playing with it, it seemed more logical for the basket to fold outwards than inwards.

Installation:
Installation took approximately 1.5 hours (performed by me a science teacher who has never done much to a car with the exception of changing the oil and installing rotors and pads. I've also replace the rear tire of a crotch rocket, but that's about it. Removing the stock components was a breeze. Not much mechanical knowledge is required. Simply disconnect the temperature sensor, loosen two clamps, remove two bolts, and wiggle the airbox off. Remember to save the bolts and rubber grommets.

The installation was rather painless if you follow the instructions. The fact that I had to use tapping screws to install and air scoop panel seemed stupid, they could have just drilled the holes.

Removing the Plastic Ornamental engine cover was easy, putting it back on took some giggling.

Removing the hard plastic breather tube and installing a smaller rubber breather tube seemed counterproductive, but it was simple enough. The hard plastic tube had to be insulated to prevent melting against the engine, this rubber tube lays in the same area. Rubber is more resilient to heat which may be better long term. It may be a good idea to zip-tie the rubber tube to the fittings, but I did not do so and the instructions do not call for it.

Loosening the clamps before installation helps, I know it sounds obvious but they are rather wide open when you get them so opening them some more really makes installation easier. Putting everything together is simple, but I do recommend putting the hump hose onto the Intake tube before installing it, otherwise clamps fall off and it is a big hassle.

Removing the temp sensor when it is 50 degree F outside is a challenge. Wrap it the exterior connector from the outside, and heat the factory intake tube with a hair dryer. This softens the rubber and the sensor pops out much easier avoiding damage. Another thing you can do courtesy of 2 Guys Garage is to use a little bit of silicon spray. (No clue if this is bad for the sensor.

Getting the filter in the box, required wiggling, loosening of the clamp, and some persuasion. Be careful the filter does bend if you press on it hard enough.

Once everything was in place, just tighten all the clamps. No specific torque settings, so clamp it all down, make sure the system does not move or give when you pull on it and you should be good to go. Don't go all Hercules on the clamps, because they will break. Installing the gasket like I said before is a pain, but if you have it face outward it goes on much easier. Leaving it in a warm room will also help make it more flexible.

Performance:
This is what the stock filter did on a 2011 CC Sport 3.55's 4X4 (Stock Truck)
EVIC showed Avg of 14.3 MPG, Manually calculated 14.1MPG (Highest 14.5 MPG)
Response was good and engine noise/rumble was noticeable, but not intense.

Currently
EVIC (after reset) shows Avg of 15.6 MPG, with a high of 15.9MPG
Manual calculation will be posted as soon as I run a fresh tank of gas (87 octane)
Response is much better and engine noise is noticeable in the cabin. During full acceleration with the windows closed, it is LOUD in comparison. ( Will take some time getting used to.)

Overall:
This was not the most labor intensive installation I have ever done. I am 6'4" and had some difficulty reaching back to disconnect the oil breather tube since it is behind the oil fill cap. Making hopping up on a stool or a step ladder would be a good idea for someone shorter. Not everything in the directions is clear, but if you look over them a few times, you can figure it out. The product is well built, and the fit is fantastic with the exception of getting the filter on the first time. Taking off the temp sensor takes some effort but can be done as long as you are careful with it. The biggest worry at the current moment is knowing if there are any leaks in the system. (I am not mechanically inclined enough to know how to tell). But if you clamp everything well I don't think it should be a problem. You are going from 2 factory clamps to 5 clamps with AiRaid so the potential of things coming loose is greater. Double checking is a must, especially since when I finished it was dark outside.

Overall this product is great and for 330 bucks if what the EVIC says is true, I will be looking at some gas savings long term in comparison to the stock air filter which looks like the worst filter I have ever owned and appears shoty when compared to even a Napa Gold filter. Engine rumble/noise has increased and it audible in the cabin at full throttle. This is something that will take some getting used to, but at the same time you know that it is sucking in more air which result in the louder rumble so it must be working better than stock.

I give this product ZZZZZZZZZ (9Z's)

That my friends is someone who is serious about reviewing a product! Nice work! I've been going back and forth between different CAI so it was great to see a review like that.

great review and pics, I have read in other threads that the air aid + k+n are open and suck hot motor air. From what I see when the hood is closed it seals the top of the unit. greta job.

I have a Airaid cai in my 2010 SHO I get about 1mpg more after install. The best part was mine was free, Airaid used my car to make their install directions :). I am going to get one for the dodge and change out the stock muffler with a magnaflow haven't decided on 18 inch or go a little bigger.

Installed my Airaid today and your review pretty much sums it all up. Can't think of anything you missed.

I'll drive it for a week and post the MPG changes compared to stock, although the numbers will have to be taken with a grain of salt as I installed the MBRP cat back exhaust as well.

any update on mileage.
The Process:
Sorry for not updating the mileage information, but I have not been doing a good deal of driving since the install and the driving I have done is not typical (lots of driving in traffic lately). I did go back and double check the installation a few days ago and everything was nice and snug. While doing the double check I disconnected the negative battery terminal and that seems to mess with my EVIC somewhat. I filled the tank up with 87 Octane (Costco Brand, which makes me wonder if that stuff is cheaper because its lower quality). I reset the EVIC during fill up and I reset my trip meter.

MPG's so Far:
Currently I have done 115 miles which equates to a quarter of a tank according to the needle and the DTE (Distance to Empty) is 275 If you add the DTE with the trip meter driven and divide by 26 (my gas tank size) you are looking at about 14.8 MPG's which is better than what I had stock (13.2) but I have spent more time in the city and traffic, along with this rainy windy weather we have in Chicago.

Observations:
What I have noticed thus far with the CAI vs Stock is that there is a larger gain in MPG's in terms of Highway driving at speed up to 75 MPH. The EVIC MPG's continue to rise. During traffic and city driving the MPG's seem to drop rather drastically. It seems there is more loss than gain when comparing highway to city driving.

Being a science teacher here is what I got to account for this. The cone filter when compared to stock is much larger and constructed of a thicker material, so although it is more ridged to increase surface area, it still has some built in resistance. During higher speed and constant movement all this is rather negligible because all in all you are getting a higher level of air flow and the wind creates a natural flow reducing the amount of suction.

During slow speeds however this resistance plays a large factor and results in the engine having a lower amount of flow which explains the drop in MPG's. The vortex tube design is more of a trade mark gimmick by AiRaid and adds more to the sound of the air rushing in than anything else. So if you want to save some bucks go with just the box and filter and reuse the old intake tube (also a much easier install). Some guys swear by the smooth tubing vs the rubber factory tubing, but all in all the amount of air flow at high speeds is already strong enough to overcome those ridges. The smooth tube vs the ridged tube would be more important in exhaust than in intake.

Thus far, if you are doing mostly highway driving with little to no traffic I would recommend the CAI (any one in general). If you are a city driver or drive a lot in traffic a CAI will do nothing for your truck, in fact it may rob you of a few tenths of MPG's. Unless you want some performance and sound then by all means please buy it.

I will post full manualand EVIC calculations when the tank is empty which will hopefully be by the end of next week.

Amazing write up.
Just ordered my airraid intake today actually.

Seems to be the best one out there, havebt heard any complaints about fitting issues or anything.

Can't wait for it to come in!!

Again, awesome job

great job, Very good right up and I definately think higher of science teachers now. I went with the K+N, I think the designe of both systems are close, and I liked the way the K+N gets its air from the fender. A little more open, and they both seal to the hood. I also got the K+N for alot cheaper. Thanks

The Airaid get's air from the fender too. I can get the Airaid right now for $313 from Autoanything. That's $56 off original cost.
