You think the spacer makes noise, try a cai, or a cai, and a spacer. Quiet, and mods don't usally go together in the same sentence. A programer is pretty quiet.

 

You really believe that adding a piece of phenolic resin is really gonna help heat soak? Please dig into a Thermo book and tell me why most intake TB's are aluminum. Funny how this popular TB spacer company talks about it's swirling capabilities, huh? Too bad what ever swirling effect is long lost by the time it reaches the cylinders.

I'd sure like to see a motor that has coolant lines running in the TB. That would be a real engine design. The Throttle body has to be hot for it to work properly? Who are you kidding? If this was the truth, then why all the focus on bringing in cold air from out side the vehicle?

This is true, but I can't help but wonder if it wasn't read from some other post and just inputed here. You couldn't possibly be making the previous statements, and then proceed to this one. The key word here is "Custom Intake Manifolds".

Boy, I better run out and buy 3 spacers for my F150!

TB spacers work on Carb'ed vehicles as they allow a longer time for the air and fuel charge to mix. This allows for more of a complete combustion.

The reason that they don't work very well in most FI applications is because on a FI motor fuel is directly injected in to the cylinder. There is no extra air-fuel mixing by adding a TB spacer on a FI motor as the fuel is injected after the spacer unlike in carbed vehciles where the fuel is added before the spacer.

 

Slick 50, K+N, Tornado, Z-Max, etc, all have dyno sheets proving that they work!

 

I don't know about the improvements of all the spacers out there but I can legitimately say that I bought one from summit(airaid) and I put it on took it, off put it on again and then took it off permanetely with good reason...

The spacer I bought did not help my mpg,throttle response or performance at all ..Just telling you the facts..

 

You need to do some research on intakes and Plentums and how Intake manifolds work before making a post like this. Or get ahold of a company called Trueleo, They make intake manifolds. They will set you straight.


As for Coolant in the TB....
Look up a KL series motor. They were used in Ford Probes, Mazda MX3's MX6's, 626's, and a bunch of other cars. Those have 2 coolant lines going to the TB. Look at a FORD 4.0 SOHC motor, it has 2 coolant lines going into the TB. My 2.3 liter 92' Ranger had the same. 98' Chevy Blazer, oh wait, same thing, 2 coolant lines into the TB. I think the onliy motor that I've worked on that hasn't had coolant going into the TB was a 92' BMW v12.


Now thank you for making yourself look like a retard, Don't post again unless its with FACTS, not you being a cocky ignorant lil....well, you know
Just TRUST me, they work if used properly. I do not suggest you using them because I have the feeling you'd have a hard time with simple instructions

 

I knew it would be a matter of time, before this debate would take off, lets get it going. They work on jeep inline motors, and ford tbi engines from the eighties. No luck on a ranger 4.0, or f-150 5.4. Anybody else get them to work on something, or not? In playing around with these things alittle over the years, it seems they show more inprovement on vehicles that have the tb mounted horizontal, verses being mounted vertical. I don't know if it's a factor or not, just a theory. At best, any improvement is slight, but on a 4 cylinder jeep, every little bit helps.

 

Keep it civil guys.... Debate them all you want - but don't get into a name calling match and make me actually do my job as a moderator...

 

Sorry, I get frustrated when people are wrong and refuse to be corrected.
I received a 6 hp gain and 2 tq on a 2001 Ford Ranger 4.0. You have to remember, when testing Thermo spacers, you test when the engine is HOT.
The other BIG note, on my 93' MR2 Turbo, I gained 21 hp and 24 tq from putting the phenos in(now @ 567 rwhp and 548 rwtq)

 

You got what? Let the rest of us in on the seceret, how did you get 6 hp from a 4.0 with a spacer? What brand spacer was it? I hope you didn't get moderated by flaming at me, I am on your side to a degree, I'm just trying to sort the facts, and find out what works, and what doesn't. AEM dyno test spacers, if there is a benifit on a particular engine, they throw a spacer in with thier cai, the jeep kits have spacers, the ranger kit does not. I just looked at my 04 4.0, and I DO NOT HAVE COOLANT LINES ON THE TB, are you sure were talken about the same part? A tb, has a trottle cable hooked to it, and a buterfly that opens to let air in.
