There are also tolerance variations from car to car so some will contact more than others and some may not at all. This may or may not be acceptable to some drivers, so its simply listed on the site as not being able to fit.

PS. If you have the 05 6MT, don't even bother with a spacer. MREV is the only way to go.

Tony --- quick suggestion
Do a small 3-4 line writeup of the revup, including what years/models/trannies have, and more importantly, DO NOT HAVE the revup.
Then do a short 2 line explanation of the mrev, and make it clear the mrev is for the revup. Then explain what other products you have for non revups.
This way it can be stickied, and we can all link to it everytime someone asks a question like ^^^.

maybe a table would work really well for this, where across the top you have stuff like hp increase, cost, tranny and down the side you just have the year.

Dyno plots of the spacers will be posted on the website very soon.
As far as warranty is concerned, assume the dealership will automatically imagine any excuse, reasonable or not, to void your warranty. They may or may not try to do that.
Otherwise, consumer protection lemon laws essentially states that any modification you make to the car must be shown to be the cause of the problem if they are to legally void a warranty.

Quick question---
Does it affect how the car sound? Can you hear the difference? Looking for quiet mod - thanks.

A 05 G35C 6MT friend of mine drove my car and commented on the fact that he thought my car is stronger than his. I definitely think the MD spacer is money well spent. If the 1/2" spacer would fit with the engine cover, I would have gotten that instead.

How does it compare to the Crawford?
This still confuses me - assuming you don't care about the stock cover fitting back on - with Crawford you get the entire plenum instead of just the spacer. Plus like the Kinetix - I read on the internet that it also lower the air temp. Well - maybe the question I should ask is - is the crawford worth $100 more?
Appreciate your input.....

The Iso Thermal spacer has many advantages.
The first being stealth. When its in, you cant see it. This is the#1 reason it was developed.
The second is it thermally isolates both the upper and lower collectors.
Thirdly, doesn't cost as much.
Its also fully compatible with boost.
It does more, costs less and is stealth. A good combination.

what difference does the width of the spacers make and how does this thing work to generate that much power in the first place?

So high that its less than optimal. The overshoot makes for good advertising in magazines but not too much more.
The MREV intake runners are longer than stock, hence they resonate at a lower frequency. The runners resonate kinda like when you blow air across the top of a coke bottle. If you make the runners shorter it will resonate at a higher frequency.
Another way to think of it is how you can tune a vented subwoffer box with a port vent of a specific length. If you make the port shorter than optimal, it will resonate really loud at one frequency but sound like hell at all other frequencies. If you tune the runner (or speaker box) to the right length (frequency), it will have a more uniform response at all frequencies.

Ohh..thanks Hydrazine!
This applies to the basic plenums too right and not just to the MREV because I have an 05 AT sedan and as I read earlier, the MREV is for the MTs.
