Well, I bought one of these to replace mine instead of cleaning it. Intake comes as a complete unit with all gaskets and sensor in place and ready to install. $180 well spent.
Also looked up the part numbers quoted in this recall and a mighty reasonable price is being quoted for the intake and gaskets. Also looked up the other part numbers and also reasonable prices.

it’s not the greatest, It’s for a Jeep but might help.
