did someone say group buy?

i thought about it, but with no experiance with an aluminum head on these trucks and them being cast from factory molds, there would be no way to tell how they would hold up, and i wasnt going to try and do a group buy and them end up not being a quality lasting part.

I'm still considering the TB spacer just to see if I can get another mpg out of the old girl. Not really interested in the claimed power because I know that's not gonna happen with the spacer on a 300. However, I'd love to at least try the spacer for highway mpg. I don't really have the cash for that right now though. If I could find a piece of the right kind of high temp plastic, it would be a fun experiment to DIY.

the only part that worried be was when you say China will cast them but yeah thats a bit steep for an unknown aftermarket part. you could always try asking for a sample I have gotten free samples before sometimes they want your business.

I had a simmalr idea with the intake hose being all bumpy what would happen if i put a tube inside making the intake nice and smooth? I thought it would create less turbulence might improve the mix a bit never know though

do you know the purpose of a TB spacer? or how one works?

let me explain, and you will see why they are a gimmick on our trucks.

a TB spacer was designed for TB's back in the day, mainly on GM vehicles where the fuel injector was in the TB its self, back when it was basically built like a carb intake with a TB on top of it, it was made to put a spin on the air to mix the fuel air mixture better to make sure each cylinder got a better mixture of fuel and air. before it ran down the short intake runners and into the cylinders.

no why it doesnt work on our vehicles.

our TB's basically adjustable plates before a long intake with a "BOX" build into it where the air sits waiting to go into the motor, and our injectors are at the end of each intake runner where they fire off and go directly into the engine,

there is no need to put a "spin on the air just for it to go into a waiting"box" where it will slow back down and "sit" and we dont need a better mixture of fuel and air mixture for all of the intake runners, because all of our runners have an injector one for each cylinder.

about all you gain from a TB spacer is a lighter wallet, some under hood bling, and i heard they make some what of a faint whine that sounds like a turbo running in the distance as the air sucks past them on full throttle.

You'd be reducing the intake diameter. PVC would work better using rubber couplers on each end. I just got done reading another site that gave the opinion I was figuring on. The TB Spacer, for the few that have used it, have gotten about a 1mpg gain under normal driving conditions. Those that have babied the pedal have gotten a little better. That $115 for the Airaid would pay for itself pretty quick if you did allot of highway driving. At $3@gallon, 1mpg savings would pay for itself at about 4k miles.

would you like to know why they had up to a 1mpg difference?? its called seat of the pants power, they were wanting to gain mpg so their driving habits changed when they installed it, they were babying the throttle, going the speed limit for once, and so on...

just like when some people install exhaust they think their mpg actually went down, when it didnt, they like to hear the sound of the exhaust and how do you get the sound? giving it more gas peddle, and giving it more gas peddle forces more fuel into it.

im not going to try and force you not to buy one, but when 50 people say its not worth it, and 5 said they got better mpg's from it, who do you think is going to be right?

I guess we were posting at the same time. I completely understand what your saying, but the fact that those who have used a TB Spacer report a slight gain in mpg makes me want to give it a try. The different ads for the different brands all brag about the torque increase (+21) or the hp increase (+8-10). As I said, I know that's all gimmick. Most folks don't care about mpg in a truck, especially not 1 or 2 mpg. These ads also claim 4mpg. I know better. However, if a steady 1mpg is possible, that's great by me. If I ordered from Airaid and got the lifetime warranty, I could give it a go and see if in fact I did see any gain at all. If not I could return it for a full refund. If I had the cash, I'd give it a go. Another mpg would put me around the 22mpg mark. Again, you've always supplied good info, but 1mpg is worth it to me since I do so much highway traveling in my work.

Edit, I haven't spent hours and hours researching, but I haven't found anyone yet that tried it and it didn't work to some extent. I've found hundreds that say it's a gimmick, but haven't tried it. Lol. I hear that allot.
