Check out what I added just today to my Sedona, made a nice little difference. Nice sound as well. Just $40.00 at your local auto store.

Nice! I am upgrading my tires to General Tires Exclaim UHP 245/45ZR18s. Should help with the handling!

Looks kinda cool, too. Is it any noisier?

Just a little under heavy acceleration. Kind of a deep tone. Under normal use I can not hear any difference. I can sure sure feel the difference. Was worth the money for sure. If driving to conserve fuel you are supposed to gain MPG by a few. We shall see. I usually get 18/25 with 90% city here in PR. Plus the A/C is ALWAYS in use. But of course with a lead foot adding an intake will decrease your MPG.

All you are doing is freeing up the engine to breath easier. The easiest way to do this is replace your stock pierce of junk Fram or who ever air filter with a k&n lifetime air filter that flows air much much better. Plus you never throw them away, just clean them with one of their cleaning kits every 15,000 miles or so and your good to go.
Replacing the whole intake does the same thing plus 20% more.. When it comes to power. But understand one thing more HP means more fuel so an intake can work in both ways. Baby the engine you will get better MPG. Stomp on it and you will have more power but worse MPG then before. Personally I think they are well worth the money.
You can always do the same thing for your exhaust system and you will not loose any MPG. Such as high flow cats, larger exhaust pipes, high flow muffler, dual exhaust, headers. Though I doubt they make them for mini-vans.
Full intake could get you 15+ HP, probably at least 10 on a good exhaust setup. 25 horse power is a good gain believe me. Hope this helps, let ne know if you have any other questions.

I was at Autozone yesterday and they had K&N flyer. He was claiming that you'll get 4-5 Gallon savings on each fill-up. I don't buy that..... that is way too much!
Have you seen any improvement in the mileage? I think HP is fairly good on Siennas.
2nd Q: Does this voids your warranty?
How much does this cost? Is it DIY yourself job?
FYI... K&N does not make filters for SIenna Maybe someone else made it.

First off adding an intake does not void any warranty. If the intake failed and a piece of it came off and got sucked into the engine and they could prove this then this would void a warranty.
Second: Babying an engine with an intake should get you 1-2 MPG. How many gallons that is at the end of a tank you will have to calculate. Go to their site and check them out and yes they do make filters for the Sienna.
I would suggest for your needs just get a replacement filter not a whole intake.
Third: It has only been half a tank of gas since I added my intake and right now I am noticing between 1-2 MPG increase.
This is what your filter will look like.

This filter is expensive $54. I don't know how much regular Sienna filter would cast.
I seem to recall that someone in the forum said it costs $40 at your local auto shop for intake replacement?
