Attached is a excel file on the prices for the plenum parts as of early 2006. Please be note that as of this date the prices are currently outdated as Nissan has universially increased their prices, however this should give you at least a good idea about pricing. As far as I am aware, the price increases were not more than 15%....
The first book has the prices from Infiniti of Scottsdale and the second book has the part numbers and their descriptions.
parts list was taken from a 1994 Q45t without TCS or active. IF you need part numbers for either of these, please let me know.
