Air Raid Throttle Body Spacer

Has anyone used this product before (Air Raid Throttle Body Spacer)? I would like to gain some fuel economy and don't know if this is worth the money. Hope someone knows

Won't do anything, except whistle a bit, snake oil for the Jeep's engine.

Here's my .02

For an engine with some form of port injection ( tuned, seq., multi....) it seems to be a waste of money. Your creating turbulence to far upstream of where the fuel is being added. Now with a throttle body or carb you may get a little better results. Now your adding fuel then getting your turbulence right away which should give you a pretty good air/fuel mix.

So are these bunk as well or is it reasonable to think you can get 1-2 MPG and have the engine feel more responsive?

In my opinion, they're crap also. I took off my stock airbox (I needed the room), and if anything, I LOST mpg. Others will disagree ....

Well knowing Iím going to get flamed big time for this, but I think they help. But, I have an auto and I can feel the difference at take off and low RPMís. With that said Iíve tried them in my other Jeep thatís a 5 speed and canít tell. Now hereís the big one, not only do I have one, but I have two of them stacked on top of each other. Both have been bored out along with my throttle body. I think possibly the taller plenum area helps. But, Iím sure itís all in my head. As long as I think it works, thatís OK with me. I donít really care as I did not have to pay for either one of them. So itís all a free experiment to me.

Taking off the air box isn't good, now your bringing pre-heated air into the engine. A true cold air intake is better but I'm not sure it's worth the money.

I had one on my '98 SE, for power I can say it did really nothing but I did get better gas mileage. A few years ago going from 220 to 250 miles per tank wasn't much but today it may be worth it. I got it for about 50 bucks and as I figured(back then)it payed for itself in fuel savings the first month. I find that hard to believe is just snake oil, even if it is only 1-2 mpg improvement.

I would love to hear an explanation on how a TB spacer could possibly increase your MPG in a Jeep, 2 MPG, that would be a 15% increase in gas mileage on most Jeeps. Think about it logically, for about a $3 part that Chrysler could manufacture and significantly increase thier CAFE standard, they would. If it sounds too good to be true..........

I personally can't tell you if there is a difference as I put mine on at the same time as the 62mm throttle body and FIPK kit. Mine is not a brand name spacer, it was made by the guy that bored out my stock throttle body.

My friend hates the whistling sound, but thinks it is a little more responsive in the mid range.

.... do a search for throttle body spacer ( if search works )

you'll likely see that it's a bunch of experienced dudes saying they don't do nothin, and a bunch of newbies saying they're wrong.

I'm not exactly an experienced dude, but I fail to see how adding length to the air tube helps a damn thing. In the days of carbuereters, sure, but not anymore.

The funny thing is that I can not explain the reason for any increase in fuel economy, believe me I totally understand any doubt here. But this is pretty simple, I bought the spacer to try and get a power increase, like many 4 banger owners, sure it seemed a little crisper but there is no way in hell that anyone could ever tell if a performance mod really did anything unless real #'s are being made and real performance parts are being replaced, and if I could remember I think Airaid said a 7-10 hp increase(woopee) and lets be real, a spacer is not going to do squat, so I fell for it. But I drove the same route, same distance, same traffic, and same driving style for years and I went from having to fill up the tank every Thursday morning, until the spacer. All of a sudden I was filling up on Friday morning...what the hell...so I ran a little test. I ran the Jeep really low then, filled it up, and I got 250 miles to a tank. I did that for a few weeks and the same results + or -. Then I took it off and I went back to the lower mileage. So stupid me decided to put the spacer back on because well, it is not suppose to do that, logic says no, all the Jeep experts on Jeepforum.com say no and well I really could not expalin it either, so who knows maybe my Jeep had a mystery cloud surrounding it and maybe I was the lucky one getting a little better mileage of my $$$. Can I explain why Jeep engineers have not done this no, but can you answer why they put those stupid looking caps on the ends of the bumpers...probally not right. Have I put a spacer on my '00 Sport not yet, I just have not had the time, but I just might when I find the time. But the thing cost me $50 or so and I got more range out of my tank.
