I have always used K&N in my diesel and got seat of pants , more sound, and more economy ........

But ; I noticed no difference at all...... not even in MPG

 

So i see that just from the drop in i wont gain much. but the idea of having the rr snorkel and the drop in is a good combo? or there is something else i can do to the intake with the rrsnorkel?

 

I'm guessing you see a lot of sand and dust based on your location. My concern running ANY high flow filter would be dust getting through in a situation where you have a lot of it. The snorkle should get cleaner air than a stock intake, but you know your driving conditions better than anyone. I would do a risk vs. reward analysis. Food for thought.

 

I thought the snorkel would help with the dust? wont it? yeah we have extreme dust here sometimes, so the kandn would let alot of it in the engine?

 

on the RR site they state that the snorkel will increase power, is that possible? what about sound?

 

bump on top so people won't forget

 

im running a K&N with a river raider, no change in MPG and not much noticeable gain in power at all. i got the K&N b/c i can clean it and re use it, whereas the OE filters can only be cleaned out a few time before they have to be replaced

 

I didn't notice any power increase.

I did the "drilling holes in the side of the air-box" mod and this gave me a great sound.

Gas mileage if anything went down.

 

drilling holes? how? with a snorkel?

 

Literally everything is a compromise. If the K&N filters are able to move more air, there is a reason. That reason is less restriction. What is the restriction in an air filter element? That's right folks, the filter media. Less filter media=more dirt in your engine. The K&N filters can boast about increased power, because with less restriction, they allow more air to move through the filter element. They also allow more dirt. To begin with, this is a dead horse that's been literally beat into the ground. The stock air box assembly is not utilized even 100% of it's flow capacity. This is why adding an aftermarket filter or intake system shows little to no power increase. The 3.8 engine simply does not NEED anything other than the stock box. If it did, you would see more across the board claims to power increases by changing filter elements and or intake boxes. Most of what you think is a power increase is simply noise from a more open air intake box and nothing more. Most people think since it sounds faster, then it has to be. For those who say that mileage seems to have dropped off after adding an aftermarket filter element or intake box, why, of course it would! Because you like the new noise so much, you're gonna be puttin your foot in it more so it'll make that noise. The last time I checked, mashin the gas pedal more didn't equal better mileage. So, does this mean all of K&N's stuff is junk? Of course not. It does mean though that before you make any changes, you need to be informed of the facts first. The fact is in this case, for the 3.8 in the JK, adding an aftermarket filter or air box doesn't add up to horsepower and mileage gains as some manufacturers claim. In fact, it can lead to engine damage through valve seat recession from injesting too much dust and dirt as well as a hydrolocked engine, from getting water into the engine, which your warranty will NOT cover. So, buyer beware.
