Welcome to the 3.4 family----
The Grim Sleeper
There is no true cold air intake for the 3.4 without some custom fabrication. Our problem is the battery is in the way. I've seen some people who move their battery to the trunk and run the intake into the fender well to achive true "cold air".
I've also seen several "warm air intakes" where people take the crome intake tube for a '00-02 honda, cut six inches off the throttle end and put a K&N filter cone on the end, in place of the stock airbox.
I've seen a K&N warm air intake kit installed on a Euro, so they do exist, just not sure where to get them locally, tho I've seen them on Ebay.
For the chip, you may want to ask around at (this is not a plug) 60DegreeV6.com. One of the moderators their (Ben) makes chips for our cars that will give you a little more "pushed back into your seat" effect.
