John,
What are you planning on doing? Are you thinking of screwing the 2 adapters back to back? If you do this, the throttle body will be rotated and the cooling hoses will interfere with the hood.

So what's the project? Maybe some kind of precooler for the intake air? To make a precooler effective, you would need to have it installed upstream of the air temp sensor (which is located just behind the MAF), so that the computer could readjust to the cooler air.

You're welcome to my adapter, if you're going to put it to good use. Email me your address (zu4two@aol.com) and I'll drop it in the mail.
