In case you missed the title of this thread, it is about increasing MPG not HP.

Warm air = more MPG
Cold air = more HP.

 

i didnt miss anything, if you are that hell bent on mpg get a prius or better yet duct the intake right off the header

 

Prius? All the extra complication . . . and cost . . . and reduced cargo capacity?? I think NOT!! We LIKE our xBoxen!!!!

 

a men to that one

 

Not to mention the additional $7K - $10K price of admission!
According to my calculations, that would buy a $&!%LOAD of gas!

 

here is a auction for a cheap $ going K&N drop in:

I'm thinking about doing this snorkle design trick, but probably using a TRD drop-in.

 

Plus you'd still be driving a Prius. Yuck!

That used K&N filter ebay thing is funny. With shipping it's the same price as a new one!

 

Alright me being a previous mustang guy I can relate to these kind of experiments. I think mustang owners have put together some of the Weirdest/most effecient/least effecient CAI/RAI out there. Next weekend when I have time I am going to remove the lower snorkel and add a K&N air filter to it and I will let you all know the results. By then I will be passed 5k miles and hopefully my engine will have finished it's breaking in period.

 

I just took my snorkel off today and filled my tank. I should now something in about 5 days when I fill up again. I figure it can't hurt to take off the snorkel. If nothing else it cleans the engine compartment up a bit !!!

 

Well, that's taking a positive outlook on things!

 

I tried it early on. I am mixed on it myself. At the same time I put mobile 1 in my manual tranny, so may not be a good test. I will say it did go up 1mpg, but my interstate use is mixed with traffic and accidents. I think on gas savers . org the better idea is to take it off the exhaust manifold and or plug in a dummy value into the oxygen or temp sensor so it runs leaner than normal.

I have the stock filter as it seems fairly free flowing and the modified one aint cheap.

 

Actually you did miss....everything.

This is an xB thread, not a Prius thread.
This is about increasing the mPG for the box, not the most fuel efficient car.
As mentioned, 10-15K more would buy enough fuel for the lifetime of my box.
You missed the title of this thread....again.
Some other points were mentioned as well.

If you reread what you wrote, you went into a rant about robbing HP from your motor w/ warmer air. Totally had nothing to do with the thread dude.

 

Thank you for pointing out the obvious. Some folks need that. I don't understand his rant, but hey, it's Monday and I'm good !!!

 

Ah, the joys of on-line forums!

 

I did this mod today, with a drop in TRD filter, reset the ECU, then right after I went to Chevron and filled my tank w/ 87 octane. I did not notice much of a engine noise change from before- maybe slight.

I'll check back with my results. I am using 16"X7 alloys(approx. 15 lbs each, about 4 pounds less then stock) , w/ 205-50-16" tires(about 2-3 pounds heavier then stock) , and nice lightweight lug nuts( 3.8 onces per wheel .. less then stock) - so theres that element. I drive a 5-speed 2006(last date produced) xA. I'll make sure my air pressure is proper(need to invest in a nice pressure guage) , the tires were last checked about 2 weeks ago, I'll check them again in about a week.

BoxOffice , I hope some of your good Scion vibes rub off on my Scion. It would be dope if I can get 5-6 more MPG's per gallon... that would be like saving $4 per tank of gas- or its basically like adding an extra gallon to our smaller gas tanks!!!!

 

I just changed my dirty air filter and put in a clean one. Do you have to reset the ECU when you put in a clean filter?

 

I never reset my ECU and got a significant jump in mileage anyway. So I wouldn't know.

 

Good luck!
Keep in mind that it seems like quite a few people haven't gotten much in the way of results for a tank or two (why, I don't know, other than the possible ECU re-set), so don't be disappointed if things don't improve right away.

 

Speaking of which, I just got the best tank I've had in a while - constant A/C has been killing my mileage.
All city driving, plenty of A/C use, but drove pretty carefully for the whole tank = 390 miles!
That worked out to a decent 37.65 mpg!
Can't wait for fall and cooler weather (no A/C!).

 

Are you saying that the 15" steelies weight 19 lbs. each? That's a lot higher then I would have thought.

Unfortunately your tires are heavier and since they are the farthest out from the hub, they become the most consequential weight on your whole wheel/tire package.
