Are you referring to the ISO Thermal Plenum Spacer or MREV? The ISO is priced at $265/5/16" spacer or $295/1/2" spacer. I have no reference to the Crawford Plenum/products. I am sure that it is a top knotched product without doubt. The Motordyne products are well worth the bucks. I have never had a regret. The MD 5/16" plenum spacer will keep your engine bay looking quite close to stock, as well.

If you have a '05+ equipped with an 6MT, I would seriously consider the MREV option(s). There is a ton of info here on these boards with regard to both product lines.

Crawford plenum is only 299 from Sharif at forged internals...not sure where your getting that price from, plus they state 9 hp at peak and 17-20hp at redline.

Don't ask me how I know all this
