Installed a drop in K&N Filter in my 4.7L V8. Made a noticeable difference. Improved fuel milage on the highway 1 1/2 to 2 mpg. Transmission downshifts out of overdrive much less.

Agreed, found the same on my 2002 4.7L. I would suggest the K&N to anyone for an inexpensive way to get a couple of extra horses and and a bit better milage.

Just picked up my 03 4.7L Manual V8 last week. Was this just the filter you put in or a complete air intake?

I get 19mpg city/21hwy in my 2001 4.7 5spd 3:92 RC. K&N drop-in with custom homebuilt aluminum intake tube between throttle body and stock air box, rubber flap removed, Fernco 4" air inlet. Total cost: $120+ 40 for K&N. Great results in response/horsepower/mileage.

I just bought a 2003 QC 4.7 auto, etc a few weeks ago. I dropped in the K&N almost right away and wasn't able to tell the difference.
I have been VERY handy at modifying intake tubes (true cold air) on other cars, etc. However, does anyone here know about any waranty problems by me changing any of the intake from the fender to the throttle body?
I guess I could ask my dealer next time I take it in. But I know what they will say. They acted as tho I shouldn't be changing my own oil as far as waranty goes. Hmm... but anyway. I would like to change my intake. I drive up some BIG hills on weekend when I go out of town. Today I was looking at this thing and think I could easily get a new hood with cowl induction and make a short intake where the filter sits right on top of the engine and fits into the scoop of the hood. Short as possible and right thru the hood, then I'd KNOW I had COLD(er) air! I'd maybe lose some low end this way but I'd get lots more where it counts!
Anyone who knows, let me know about your experience with this and the waranty.

From what I can tell, the "commercial" air intakes do not void warranties. A knowledgeable friend of mine told me that where ram-air is concerned, fuel-injected engines like smooth, uninterrupted air, whereas a carb. motor takes the direct force. Of course, the air filter smooths the air flow regardless. Fuelies do like cool/cold air.

What is considered a "commercial" intake system? Most of them look like someone is just trying to sell a noisy chrome piece of sh!t, so I can't believe one of those wouldn't affect a waranty while a nice home made (and full functional) ram air, etc would!
I wonder what they (the dealer) would think if I made a ram air in the hood and used a shorter intake that sat directly under the scoop with a filter like the triagular shaped Edlebrock washable?

1 1/2 to 2 mpg is about what Difference it made to go to the K&N. These engines like a lot of air. I have a 94 Dakota with a 318 automatic with 3.55 gears by the way. The reason I know that is I took the paper filter out of the stock air cleaner assembly and drove my truck for a short time without an air cleaner. During that time, I noticed that the persistent pinging that occurs with these engines appeared to stop and seemed to have a lot more power. It is well known that the paper filters that come in these trucks offer a lot of restriction. I thought that since that I was going to give this truck to my dad some time in the future that I needed to go with the stock replacement drop-in filter. When I did I noticed the that some light pinging came back or at least it was loud enough that could physically hear it now. So I flipped the breather to allow so more air to come in and it helped. But, it really wants a bigger filter with more surface area. It is a good idea not to throw away the prefilter that is around the stock paper filter. I used it to protect the K&N drop-in. It catches a lot of dirt and dust from entering the K&N and drying it out. I have had it on this truck for over I know 15,000 and it looks new. I checked it other day to see if it needed reoiling and it looks fine with just a minor trace of trash in it. I wish I had paid attention to the size of the prefilter because it is actually somewhat larger than the replacement drop-in K&N. I could have tryed several of the other filters Advance had in stock and got the biggest one especially since I ended up flipping the lid on the air cleaner assembly. I could have used it that is for sure.
Another thing you can do is install a set of plugs that has the center electrode exposed like AC Rapidfires, Bosch Platinum +4's, etc. and a hotter coil like the MSD replacement coil if your truck is mostly stock and not running too lean due to modifications such as throttlebody or intake manifold. You can take a set of stock plugs, bend the ground electrode up far enough away from the center electrode to grind it back to expose the center electrode, bend back, and set the gap. I run Autolite 3922's. I haven't cut the electrode back on this set due to fact that it appears that I am very lean now. Plan on trying it later. I have done this with the plugs in another Dakota I owned and it works very well.
My mods currently are done only with the intent of improving power along with gas mileage. I have a modifyied beer barrel intake with the runners shortened 1 3/4". While this intake flows more air, it also leans out the engine some. 2.K&N stock replacement air filter. 3. MSD replacement coil. 4. homemade modifyied throttlebody - thinking of replacing it with the stock throttlebody due to the fact that step in the stock one helps so much with low end torque for around the town driving. 5. Brass cap and rotor button - if you run aftermarket ignitions or hotter coils you will find that you have to replace the cap and rotor button sooner. Esp. the cap. 6. Distributor sync set at 12(or 6 if you use the DRB111 scanner).
I want to install a larger K&N and replace the cat with a high flow unit. Also, replace the stock muffler for a Dynomax race Magnum or Bullet muffler.
What is the opinion on what effect going to a high flow cat and good aftermarket muffler will have on gas mileage? I plan to kept the stock 2 1/2" single exhaust, but open up the pipe to use a 3 inch inlet and outlet cat and 3 inch inlet and outlet high flow muffler.

I just put the largest RX universal K&N filter on my girlfriends Trooper and took out the old air box. This made a huge differents in shifting and has a bit more power now. I just got the same filter for my 97 Dakota, 5.2L. I am thinking about putting it on without using any tubing between the filter and engine. Is this ok to do? The reason I want to do this is because of the added room so I can put a larger fillter in and that the universal filters have a soft rubber shaft that I can't attack to the stock rubber hose on my engine. Any suggestions or thoughts?
Thanks,
Ryan

Yeah I tried something similar to what you want to do Ryan...it was great when the truck was cold but once it warmed up the show was over. She doesnt like the hot air.

Thanks for the reply guys. What kind of hard tubbing would you suggest using to get the filter away from the heat? PVC? I know I will have to put a small heat shield in somehow too.
How did you fix the problem TheDonNonn?

Ryan there isnt really a way to keep the filter right at the throttle body without it getting hot. Thats why all these aftermarket (and stock, for that matter) tubes and filters pull the air from the fender or the front of the truck or whatever, because the air is cooler there. I made one (for my old 3.9) with a K&N cone. I used 3" PVC with a 45 degree elbow and some rubber couplings I bought at the hardware store. It just clamped on to the stock airhat. Real simple looking. I painted it with high heat paint like for BBQ grills. Thats about it. Hope that gives you some ideas...

That might be possible, but I'm going to guess that it would take a lot of heat to get the thing on fire. And it defenetly wouldnt just "combust" spontaneously. Denscharger actually makes an intake made from PVC (not for Dodge I dont think), if PVC was that bad they would not be able to sell it.
