I am doing a new project on my Alero. First off i have already replaced the spark plugs and spark plug wires. Also i have put a drop in K&N air filter in it. This was a good increase in power but i wanted to do more than that.

Next I was planning on buying a new upper intake manifold that is bored out to 65mm, and putting a new 65mm throttle body in to match it. The only problem i have is that I'm not sure if my intake will fit the new throttle body. Will i have to purchase a new intake? If i do how big will it have to be? 65mm?
