Has anyone installed a Throttle Body Spacer on a 2006 F150 5.4L
I wanted to know if these really are worth the $100?
Thanks for and info...

 

I'm not sure on the three valve but they do not work on the two valve and the results are prob the same for your motor.

 

ONLY to the guy who sold it to you!

 

Can't say it would really do much for you.

 

I've heard that they are better used for paper weights I was curious about it to until I heard more and more complaints on it

 

I would use one - if it had a couple nitro ports in'er

 

the helix type throttle body spacers are crap and will hurt your performance and MPG, on todays modern multi port feul enjected vehicles

 

I have heard many things about them from multiple sources and none of it has been positive.

 

They do make a good nitrous plate just ask neal......

 

I got one for free and installed it for the hell of it. No difference in performance or MPG but I did notice a difference in sound. When I floor it, really sounds kickass!!!!
I would NOT spend $100 for it (or $75 or $50 or $25....)

 

actually they do increase power. will you feel it? probably not. the common myth is they spin more air in which they do not. in order to understand how they CAN work you need to understand how and engine works. when your piston is reaching TDC on the exhaust stroke there is a duration when both intake and exhaust valves are open. this is called valve overlap. the incoming air from the intake valve helps push exhaust gasses out the exhaust valve. this is called scavenging. the more of the exhaust that is able to escape before the next compression stroke the better(more fresh air=more oxygen=better combustion). the added turbulence created from the throttle body spacer helps this process. why is it not like this from the factory you may ask? for the same reason they dont put on good flowing exhaust. noise.

 

The last thing you want in your intake tract is turbulance. You want velocity. Those things are a joke.

 

Yes, right on bigtruck and 06socomfort!

 

That is the only thing they are good for, what a joke

 

Just my opinion on Throttle Body Spacers "THEY SUCK" My wife bought me a Airaid Intake and TBS Insatlled both and took her for a ride in the new unleashed beast. After getting to 35 I looked at her and punched it. Needless to say My face went into the steering wheel and busted my nose JK But she died laughing at how pitifull it was. I turned around and ripped the TBS out and put the New intake back on and it runs perfect and makes a differnce. So dont waste your money. Plus my kids make enough noise so I dont need a TBS screeming at me all the time. Looking for my Edge now
