Why are plenum spacers so expensive?

$250 plus for such a little bit of material plus some bolts.

The gains are certainly worth the money, but I would think that they don't cost much to make.

One the other hand, I can understand why my MREV 2 cost $446. But nearly 300 for a spacer?

I think I will start a side bussiness specializing in plenum spacers.

EDIT: I certainly don't want to give the impression that I don't think Tony's genius shoould not be rewarded: I simply don't understand why others are not marketing plenum spacers, that is all.

because he uses one piece of metal instead of something casted or made with a cookie cutter (assuming your talking about motordyne's product) and just the fact that his stuff works the best and theres a demand gives him the right to up the price.

IMO its worth every $.. plus your a 6MT you're not going to be looking at the spacers anyways

OK, R and D I understand. However, why wouldn't I want to run the 5/16th spacer w/ a Rev Up. I was told (I believe by Tony himself, plus I remember reading it in the literature) that the 5/16 spacer was the way to go (1/2 makes it run too lean, plus requires a new cover).

1/2 changes a/f no more than 5/16 does; it just gives more power-uptop and makes you remove your ****ty plastic cover (and who really wants that POS on their engine anywyaS)

My question was to Klumzee: You seem to imply that I don't want a spacer at all...based upon your previous posts you are highly knowledgeable....did you mean that I don't want a spacer at all? Please explain

R&D, tooling, advertising, overhead, websites...etc. Eventually, another company will modify, lay claims to improving the original product but without offering the customer service or technical support.

Easein: That was the intention of my original question: I did not mean to devalue Tony's outstanding technological contributions. My question was why others don't also produce plenums, since the profit seems very high. Does Motordyne have a patent?

I'd like to hear more on this also.
I have an 06 6MT myself and have not been around since the beginning to know all the different MREV levels that have come along. It was my impression that you would use the MREV2 lowe plenum with a 5/16" spacer.

Yes...I went to the Motordyne site and re-researched the MREV2/5/16 combo. MREV plus 5/16 spacer is the way to go. I just got nervous because Klumzee stated that I don't need the spacer and I have found him to be highly knowledgeable. I Im'ed him, so hopefully he will clarify.

Maybe I will also call Tony and double check w/him.

I also found that another site (conceptz performance) has the MREV2 for $321, $125 less than what I paid.

The MREV and the MREV+ were originally paired with a 5/16" plenum spacer for the RevUp ('05 + '06 6MT) motors. This set-up was deemed to be the most productive inlieu of a 1/2" spacer.

The new MREV2/spacer combo installed on non RevUp engines may create a lean condition. As I understand it, with regard to the RevUp engines, the MREV2 mated with a 5/16" spacer is good to go.
