Post subject:  Throttle Body Spacer?
Does a throttle body spacer combined with a intake system really improve performance as much as they advertise?

No. They are both a waste of money.

Stick with the stock airbox setup and a good filter like WIX.

The Helix Throttle Body Spacer on my ‘95 Tahoe made a noticeable difference in both power and mpg. Regarding the KJ, there might be a theoretical improvement, but not noticeable when the spacer is installed independently. However, those of us who have made a custom “homemade” air inlet from the grill to the factory air box will say, “YES” the added air inlet has made a difference in both power and mpg. So to go back to your question, I think the spacer will become more useful after adding more air and a better flowing filter. The Amsoil is going to be the best filter for flow and filtering. KY LIBERTY has a throttle body spacer and believes it is noticeable, but he has also customized his engine settings.

I agree with sleeve84028, that you should not spend your money on any of the aftermarket cold air intake systems when you can keep your factory air box and add an air inlet for much cheaper. Check this thread out:

I'm curious about the steps required for the dryer vent setup but I also have concerns about a setup like that sucking in rain when moving down the highway...

Correction: I do not have a throttle body spacer and do not believe that they make a difference. I have a Fastman throttle body, which does make a little difference. I also have an AEM BruteForce intake with a Profinish-Proglass hood dumping air into it, and heads that have been machined and polished. That is combined with an aggressive, custom B&G flash. The combination makes a very noticeable difference.

From what I have heard on this forum, routing air through the grill past the radiator and directly into the factory box with a good drop in will give you a similar result to my hood and air intake.

been running mine for almost a year now attached right to the grill and no water problems at all, of course I use a Amsoil filter which was the finishing touch, I have been through some rain that you could not see as it was blowing right into us, snow that covered the grill and headlights and never a problem, and it does suck air in as you can hold your hand at the grill 3 inches in front of the opening and when you hit the gas it will draw your hand back in

So the helix spacer is a no go for more power huh. Bummer i was hoping with some of the spacer/cai kits i have seen for the wrangler that it might help some on the liberty also. I found a spacer and cai for $50 local, but if there is no advantage then that is $50 back in my pocket.

Just my 2 cents.. I have both a K & N intake and an Airaid throttle body spacer on my '06.. I have not had it dyno'd but the butt dyno says yes there's something there.. My goal when I purchased both items was to improve the MPG'S which it did an the power boost was a bonus.. I noticed it most at take off, improves low end torque I guess.. if your looking for that wow power boost, look elsewhere if you want MPG'S an some off the line boost then your looking at the right mods.. I also have a Gibson cat back which helps to an sounds killer...

I have the K&N intake setup on my '05 and was thinking of adding the Airaid throttle body spacer as well. I was wondering if it will fit since it needs at least another inch of space between the k&n tube and throttle body.

Post subject:  K&N Filtercharger and Magnoflow exhaust experience
My install two years ago of the above mods on my 2005 sure feels like more torque and better acceleration response. Maybe a little better MPG if I keep my foot smooth on the pedal.
No spacer is necessary said the K&N rep at a truck and jeep event I attended. In theory I like the idea of swurling gasses but he said the K&N is designed to stop intake air turbulence so that the air flows right down the throttle more quickly.

Any other information or facts on this subject?

I want my engine to last more than 100xxx so Im staying away from K&N :? I dont feel the extra 1 HP is worth the amount of dirt being let through the filter.

and......... just for some information, there is no way in hello that you will hit enough rain to hydro lock your engine. the amount of rain going into your intake directly will have to be more like you driving into a creek or wave, a solid flow of incompressable liquid versus a mostly air with rain drops in it rainy weather.


an old school mechanic combustion chamber cleaning trick is to stick the hose in the intake while holding the throttle at about 2500 or 3k rpm and turn it on. cleans the hell out of the chamber and totally freaks out anyone who sees it. my dad told me about it and i didn't believe till i tried it

i have done this on bmw motors when i was out of seafoam or tranny fluid as they all do the same thing when dumped into the intake
