few simple questions


1.Are they worth it?

2. Are you running one and if so what brand?


3. Why did you choose that brand?? performance/cost/easy install/other

 

In my case it was worth it. Bought the truck with K&N so i switched to S&B. K&N was very loose, i was worried about dust going though.

I really like the S&B set up.

I don't recommend k&n.

I have yet to see a single shred of evidence that an aftermarket intake does anything at all for a mostly stock truck.

Lots of people also talk about the Home Depot Mod. Easy and inexpensive. But I haven't seen any evidence that there's any improvement there, either.

By personal experimentation, I know that if the air is too cool, you'll lose efficiency and mileage. That's only important in the winter when it's near freezing.

I have not seen any data anywhere - despite looking - that there is an intake charge temp that is too high in normal operation.

Save the $250 for something important.

this is why I was asking cause I had the same thought. I would like to see a stock truck on a dyno trying every intake.

I have done every upgrade I have wanted. Banks claims every company has worse ratings then the stock intake..

 

Save your money!!

 

I have a K/N. Lost fuel miles, sounds cool.
Would not recommend!!

 

I think I've posted this more times than I can count in regards to air intakes. One of the first things I read after becoming a Cummins owner.

UNDERSTANDING AIR INTAKE SYSTEMS (PART I - AIR DENSITY) - TDR ISSUE 56

UNDERSTANDING AIR INTAKE SYSTEMS (PART II - AIR DENSITY) - TDR ISSUE 59


As for what I run, I have a modified stock airbox, aka home depot airbox mod and a stock replacement Fleetguard air filter.

 

Also I live in high altitudes so that has me pondering about RESULTS

 

OP, quick question, what are the goals you hope to gain from adding an air intake to your truck?

You asked three questions that probably ought to be qualified.

I'm looking at your sig block and you have some fueling mods. The feedback you've been given so far is right on the money for stock/<500hp trucks.

But, if according to your mods you need more air then maybe an intake will be of benefit to you.

So, I guess what we need to know, where does your truck stand? Have you had it on the dyno? Any black smoke? Programmer? I'm coming at this at an angle of fine tuning.

 

My goal is to hit 500hp some day and I am very close to that goal. I have no plans of going bigger than 500 hp cause I have no need to . I just got my new turbo on to get me closer to my goal. I am running a smarty s06 pod and I took my edge off. I may put the edge back on or a mp8. But im in no rush for that so I will think about it. in order to hit the 500hp mark I will have to stack the smarty. but I want to hit the dyno first before I out the edge or mp8 on or whatever I choose down the road.

I was just thinking about a cold air intake for my new turbo or a new high flow filter.. as I said before I would like to see a test of all cold air proving that they are worth it..


G and J diesel has a big event coming up in august in Billings MT and they have a dyno to use. But I might run up there soon so I don't have to wait in line for hours to use the dyno. I called them to use it only a $75 charge but its currently under repair..




I know a lot of guys that run cold air intakes and I have never seen an improvement on any of the trucks..... I have no problem wanting to spend the money on one but I just don't want to waste my time on one if it will do me no good

 

I have a Volant CAI, with 2 air filters, LOTS of turbo whistle and the engine seems more responsive, the baffled down pipe to the turbo is no longer there, the trip computer shows an increase of 2L/100 Km, I have never really done a real fuel consumption calculation since installing it so I am not sure about the displayed fuel economy increase , but it is certainly not worse than before and I cant really say there is any more power, but when I put my foot down the turbo spools up way faster than before. Advertised HP increases for CAIs are very low anyway so you may not even notice it.

 

I have no idea if this is accurate, but somebody once said that in a 7000 lb truck, you won't feel a hp gain of less than 50. Whether that's true or not, don't expect to notice a gain in power just from throwing on an intake.
With that said, I have an S&B kit on my '07 which I added after doing 50 hp injectors and EFILive tuning. I can't say that it's gained power, but cruising empty at 100 km/h it only pushes 5-6 psi now, where before it was 7-8. So I'd say that means the turbo doesn't have to work as hard to move the same load. I also like the whistle.
If you're on a tight budget, I'd say leave it be. If you can swing it, why not?
Also, it was a breeze to install and I chose it over other brands on a whim.

I have done enough mods to feel a lot of improvement. I went ahead and said screw it im doing an intake. I went with the s&b. My new turbo doesn't have much whistle and there isn't a silencer to remove. but with the new intake I can hear it now. I also added the scoop and it doubled the sound.

im not sold on cold air intakes but it can hurt but I did find some dyno results to see some improvement{showed a gain of 4hp and 10TQ on a stock 2005 cummins} and with a new turbo what could it hurt

 

I think my Volant was only supposed to add 8-10 HP, not much, but as I said the engine is more responsive now and since I never touched my silencer ring , the whistle which is very noticeable is obviously due to more air flow, not trying to sell you guys on it , just giving some facts. It would be interesting to take a ride in a truck with the HD mod and compare the two.

 

If I may interact here, I've had the stock, Banks and now the S&B which was original and modified. Here's what I found on a basically stock engine.

I retired almost 8 years ago and moved to another state. My wife and I travel each year to see the kids and grandkids. For this trip we take the same routes,usually stop at the same stations and during the same time of the year. Sort of a constant variable. When I do fill I cap the tank to where I can see the liquid so I know the hand calc is accurate. Oh, and the weight was about the same. Only major difference was a change in tire size from 265's to 285's and from the original threads to MT's. Since it consist of long hauls between stops, it was using cruise control and the same speed of 70 mph.

Over time I documented the mpg's and while using the 3 different filters noticed there were no real improvement from any of them. The mpg's were constant to a high as 1.5 mpg gain. But this so-call increase was not constant, since one year I would get the improvement over a stretch of road and not the next year in the same run over the same highway.

Either a wet or dry did not make a difference. After time I found out it was easier to keep the S&B and get an aFe dry washable filter and servicing it was easy and cheap due to the reusable material and not replacing it all the time.

If your going to go for high horsepower, get the CAI unit and actually for cost, the S&B is cost effective using a reusable dry filter.

For a wet filter, if your not servicing it right, it's easy to get the oil to suck past the filter material and coat your MAP or turbo fan blades. This can effect your engine performance, and if enough oil is on the turbo blades, throw it off balance. But this would take time and a lot of oil.

Or stay stock but get the thicker filter, I believe it's almost 4 inches instead of the 2.5 thick stock filter.

I came from the old era of diesels need maximum air going in and no restriction what so ever going out. The rest would be gravy. But since the changes in electronics and performance improvements, I'm slowly considering different thoughts.

I have seen no real improvements in mpg's that would justify the dollars I have spent, except for the maintenance set up now that will last me for years to come. But was it really worth it ?

I will say, I've learned well over 40 years ago to watch what the manufactures say and the salesman preach, for they are trying to sell you something to put money in their pockets that came from your pocket.

Where do you want that money to be at ?
