I just bought a 2005 jeep wrangler rubicon and am trying to add a little HP while most importantly gaining gas millage. I have looked at throttle body spacers, COI, and a performance chip.
Not much will help a whole lot. What you get with the 6 is what you get.
Sure mods help but you dont gain a mess load unless you were to ad a turbo or a supercharger.
I don't get you guys being so crappy about someone making a post that was already made 5 years ago. If there were no reposts, there would be nothing new to talk about and this forum would die. So chill out, just because you've seen it before doesn't mean someone else has. It's people like you who run away decent jeepers who come here just to learn, share, and have a good time talking about jeeps.
hey congrats on the Rubicon, yeah not much you can do on the power. just take it easy on the gas pedal for the MPG. you just have to get used to it beeing a jeep and not a sedan, you will adapt to its drivability in no time. Good luck
Thanks, this is my third jeep but first wrangler and I LOVE IT! My jeep grand leredo that I just got rid of got better gas millage..... That is the funnny thing about the gas millage.
seriously, everything you asked about has already been covered many times. click the search function at the top of the screen. heck, one of those things you asked about is even linked in my signature.
The only thing to help the mileage is to go easy on the skinny pedal. The only thing those mods will do is lighten your wallet faster than the gas pump does!
a turbo works basically by cramming more air into a a cylinder....inwhich more fuel can be injected into that same cylinder.....so not really a fuel saver
I believe the best thing you can do for HP and MPG is re-gear - though I have no idea what size tires you are pushing and what your current gear ratio is...you might already be up to snuff in this department.
Thanks for all of the constructive comments. To those who like to bully a post…. It only shows a lack of self-esteem when you try to make yourself look good at the expense of others.

We only bully the posts of those who are incapable of constructing a simple question and then are incapable of understanding the answers they get.
Someone must have perceived that pair of shoes fit you quite nicely.
OTOH, some of us don't really have self esteem issues and just like kicking idiots around. Kinda like a soda can laying in the street, if you time it just right, you don't even have break stride to send it flying.
We'll just call you Soda from here on out if that's okay by you???
The cheapest, well not the cheapest but best way to get more HP and mileage, is to swap in 5.3L vortec, or a desiel. But neither of these are cheap, what you get is what you get, you could do a stroker for less than a V8 swap gain some HP but not much for mileage. The best way to get more power is get really small tires and make it a low rider. Or trade it in for a honda civic.
get used to it bud. You have to see things from the other side. Every day brand new members ask the same fundamental questions that are covered in the FAQ's and expect long explanations. It tends to clutter the forum and it is irritating for those with real troubleshooting or technical issues that legitimately need help. That's why you'll see alot of "Just ****ing SEARCH already!" responses. They don't go unwarranted.
A good sense of humor and thick skin (not skull) will go a long way here as well.
Since it was inexpensive, I ordered the air tube/throttle body spacer kit for my STOCK 06 TJ from Rusty's Off-Road. All it is is a TB spacer, a piece of hardware to reposition your stock air tube, and a K & N filter. I'm not saying it's a miracle worker, but amid all the intake bashing, for around $120 I saw a slight improvement in MPG and a slight increase in 'pep', especially when pulling the RPM's out of the basement in 2nd-4th gears. Maybe it's because I'm pretty much bone stock right now, but the money spent is justified by the albeit slight but noticeable increase. Just my two cents.
Because on the 4.0L engine, the air intake is most assuredly not restrictive in the least. There are quite a few cars out there, like the Mustang for example, that have purposely restrictive air intakes... but the Jeep air intake system is not restrictive. Its maximum supportable CFM air intake level is literally well above the maximum CFM air intake the engine is capable of pulling at high rpms and WOT. This is directly from a confirming telephone call on this very subject that I personally had with Jeep engineering, specifically their most senior engineer that had contacted me on a different issue earlier in the year. In other words, it's not hear-say. And as I personally run a "less restrictive" (not really though) K&N with a TurboCity air intake tube, I can say there is no perceived performance difference... unless a noisier engine can be termed to be performing better. And of course there is always the placebo effect... I spent over $200 for a FIPK and it's louder so my engine must be definitely more powerful now.
The most telling chart and text accompanying that chart from that test is this one...
"In the chart (below) it's important to note the different test durations for each filter. The AC Delco filter test ran for 60 minutes before exceeding the restriction limit while the AMSOIL and K&N tests each ran for 20 and 24 minutes respectively before reaching max restriction. In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms. Compared to the AC, the K&N "plugged up" nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt." (end of quote from the air filter test)
TBS: It doesn't do anything. Here's why: On the Jeep TJ, the air and fuel mix AFTER the throttle body, not in it. Therefore, the air/fuel mixture is the same in every way whether you bolt the spacer on or not.
That's nothing more than the well-known placebo effect at work.
With the type of throttle body the TJ uses, a spacer placed under it will do nothing. Spacers can do wonders under carburetors and older style throttle body injection systems where the fuel was injected into the throttle body itself, but not on the TJ's throttle body that passes nothing but air through it. Fuel doesn't even come close to the TJ's throttle body, fuel is injected well below the throttle body, directly into the combustion chambers via individual fuel injectors.
Actually if you add it up $120 is recouped in around 9000 miles. If you consider a +2 increase in mpg at a savings of .013$ per mile. 300 miles to a tank x .013 = $3.90 savings per tank at $1.90 per gallon. $120 / $3.9 = 31 tanks. As much as I drive on a daily basis to work it will take me less than 10 months. I never said it was the greatest mod ever, it's my opinion. That's what these threads are for, right?
I don't really see that as a thread-specific answer, but ok. I'm just giving the guy some input. FYI: when I add the phrase "just my two cents", that means it's my experience, my data, and I'm passing it on. It's not the Gospel, you can take it as you'd like. Nevermind Soda, don't buy it, it's garbage.
Take it out of gear going down hills. That will save you a few drops. K&N filter helps a little for more horse power. Spacers are just high dollar noise makers.

And folks think I'm mean. Although, you should have waited to send him over to General 4x4 on Tuesday. That's the day for mileage and horsepower threads.
How do you know what gains it makes, I couldn't find any charts for it?? Those numbers they posted are no doubt high rpms and therefore just about worthless in a TJ, just like every other programmer/chip we have ever seen
Ya'll making me laugh down here in Texas. Sometimes I just read the threads just to get a good laugh. Hey, I got a 06 4 banger with a 6 speed, 3.73 gears with 31's and I get about 21 MPG but I have no power. I knew that when I bought it. It's a Jeep and I just cruise down the road in the slow lane. Ya'll keep up the good work. I've learned alot here and the search button is amazing.
if you think this is bad try pirate. this is nothing, but these threads start every week and if you use the search you can find tons of useful information and blaine and unlimited really know what they are talking about.
