No worries, I was just unsure whether or not there was confusion as to whether he was asking about a gasser or a diesel.

 

Not a problem, only way to be sure about things on a forum like this, when you can't see the other person is to ask.

 

nobody has yet to answer the op's question about increasing fuel mileage just mentioning this cause im curious myself didnt buy my truck for fuel economy but every little bit helps

 

There is no way that anyone can definitively show that any one mod had improved mpg on any truck/vehicle.

At best, the mod could have contributed to mileage improvements, but there are alot of variables that go into mpg figures and quite a few of them are not able to be controlled by any driver.

Could doing mods help yes, but in order to realize that benefit terrain, ambient temp, speed of vehicle, windage, barometric pressure etc also have to be at ideal conditions.

I would not buy mods for the purpose of mpg gains whatsoever. Can they help, they sure can, however, if they do that's icing on the cake. Anybody that tries to sell you the bill of goods that they did a mod and that helped eek out 2 mpgs extra is either fudging the truth a little bit or their calculations are off(and they may not know it or doing the calculations wrong) or they aren't giving enough credit to other factors that apply to mpg as well.

Hell, even doing a simple oil change can help with mpg figures for a little while or any other simple routine procedure.

 

um uh well if you switch to a k&n is a person more likely to

A: notice a litle increase in fuel milage and truck performance do to better air flow
or
B: not notice anything and wonder why you bought it in the first place

 

Forget fuel mileage, if it helps great but don't use that as a decision maker. Easy of cleaning, ease of changing etc are better guides to decision making.

As to increased air flow and performance. It depends on where in the rpm range that increase airflow happens. For the 6.0s, max tq is 2000 and max hp is at 3300, but a/m intakes don't flow more then the stock one until you hit 3700 and that's outside a stock, or just tuned truck(keeps the peak rpm ratings for tq and hp) so for the 6.0 it's a waste of time and money. That's what you'll need to pay attention to in order to figure out if it's going to be a benefit or not for performance.

You might notice somethings or might think you notice some things. The question is, did it really make a difference or are people wanting to think it made a difference because they don't want to feel like they wasted money on a mod that did nothing.

There are benefits to a/m intakes, just make sure it when it does have those benefits, it fits what your vehicle does(I'm thinking of airflow at rpm in particular here).

Alot of people's claims about the benefits they experianced are too touchy feely for my liking. You can logically argue flaws about them. Do your own research first(look at facts, not people's opinions of the facts) and then ask about opinion about the mod and try to go from there.

 

But you are only referring to the 6.0L's and 6.4L's., and that idea does not apply to all diesels. 7.3L's have very restrictive airboxes, even with power made with nothing more than a chip. You guys with the 6.0's have a much better stock intake.

Forget about intakes giving you fuel mileage. Any and all fuel mileage claims by using aftermarket intakes are bogus anyway. Stock intakes, even the more restrictive ones, can still flow sufficient enough air if you are easy on the pedal and driving for mileage. Once your foot is planted further down, you aren't driving for mileage anymore, and all bets are off. So if you truely are driving for fuel economy, the type of intake you have won't really make that much of a noticeable difference, because any intake can flow enough air for mileage purposes.

 

No, that's why I said you need to look at the RPM range that the a/m intake flows better at on an individual basis(I say individual basis, because I have moved my rpm range upwards to 3900 for pk hp so I would benefit from increased airflow of an a/m intake).

I was using the 6.0 and the 6.4 for example purposes to show engines that I knew for sure couldn't benefit from a/m intakes.

 

OMG can we have a thread on a gasser witout diesel bull being thrown in.

A K&N filter and/or a K&N intake will not make a big difference in power or fuel economy. A K&N will not destroy your gasser either. I've been running an FIPK for a while and UOAs look great, the MAF stays clean and there is ZERO dirt or dust in the intake tubes. I highly recommend getting an outwears for the filter it really helps to keep bugs and other crap out of the pleats of the filter. Don't over oil the filter either after its cleaned.

 

Not with the intake questions, I don't think so. There are people that come from gassers and get a diesel and they "knew" that the K&N worked on their gasser, so why wouldn't it work on their diesel. When you start talking about aftermarket and people that don't know(for whatever reason) that there is a difference between how the aftermarket affects a gasser versus a diesel, then you get conflicting stories.

The issues that K&N has with the diesels(especially the 6.0) doesn't appear hardly at all for gassers, yet you have people mentioning it ruins engines.

Now as far as airflow and performance goes, that depends on the individual vehicle(especially if the vehicle is heavily moddified) rather it's a gasser or a diesel. Mileage gains are a crock, there is no way that the everyday person can easily and cheaply test to see how much gains that intake net them.

 

This is the OPs post.

Nothing to do with diesels, nothing, don't care how you look at it. Now the OP has to sort through tons of diesel garbage to get his answer. Just tired of it myself I guess.

 

Yes, but you have people that are going to answer this question based on their experiances, despite the fact if their experiances are diesel related or gasser related. Your going to get both in in here, rather you like it or not.

I didn't open the thread to diesel discussion and my comments on airflow and performance and supposedly mpg benefits from intakes I believe to be sound rather or not your talking about a gas or diesel.


There are tons of threads that get posted every other week that are the same exact thing that I'm tired of. I just wish the moderators would do a sticky folder of the most common items(intakes, what exhaust, tuner, gas v. diesel, diesel v. diesel, gas v. gas, mpg threads) that seem to crop up all the time and no one uses the search funtion. I doubt the moderators would do that, it would be rather time consuming and as such rather or not we like to deal with threads they are going to be here and continue to still be here.

I do agree with you the OP will have to shift thru a lot of posts to come up with the answer of not to shop for mods with the sole purpose(I say sole purpose b/c that is the only purpose that he listed and as such that is the only purpose that I can conclude that he is using) for mpg gains, but like I said, diesel was brought up in a general intake question for a gasser because you have people that have had bad experiances with that particular intake and it caused problem with their engine(rather it was their own or another engine that was the same as theirs) and I would imagine were hoping to help him to avoid that issues, but didn't know that intakes that work or don't work for one engine the case may not be the same for the other engine(providing it's a totally different engine, not the "same" engine in a different truck).

 

amen brother amen

 

Thank you!

 

This is in reference to a CAI kit but the intent is the same.
