Aftermarket Intake Spacer?

I came across this on ebay.

Does anyone know if this would actually gain power? I know reed spacers add low-end to 2-strokes, and this looks like the same concept.

It makes a nice difference on two strokes, but not quite as big of an impact on a 4-stroke. It gives the fuel a little more time to atomize before it reaches the cumbustion chaimer helping it to have a more efficient burn. Im considering it just so my airboot from the airbox might fit a little better.

ok, thanks for the info.

When i took that boot off the one time, it was a pain in the arse to get back on.

I keep a spray bottle of 90% rubbing alc. in the garage...spray it on, slide it on and the alky flashes off...also works good for cleaning your hands and is awesome for windows...

I made a 1/4in intake spacer for my 440,I really did not notice a big difference,but there was a small difference.

I know that intake spacer will help on your low and midrange power, but is aluminum the best material for it?
I know aluminum will transfer heat to the incoming air, thus keeping the fuel atomized but making it less dense.
Or would it be better to make one out of high density plastic to help keep the heat out of the intake charge?

I guess if you were trying to get every oz of power out of it it would be good. A lot of drag racers make theres from plastic or even wood for that reason.

Well like i said, i mainly want it to move my carb back a little so the airboot fits better.

[yfzrider310]

O then nevermind. How much does the spacer cost.

[drew416ex]

Its gone up quite a bit, its up to $56 which is why I still dont have one.

[yfzrider310]

wow....how hard would it be to make one....if you have the tools

I just used aluminum because that is what I had laying around.
I had used a milling machine to get the rough shape and to put in the groove for the o-ring,then I bolted it to a spare head I have to get the final shape(so I did not get any aluminum in my intake on my quad) and I bolted it up and made sure it fit good
