It's a pain & I don't recommend enduring this project for 3.2 or smaller till the engine is out. I removed the intake & fuel rail. Bend the engine lid mounting tab straight up for more clearance & remove the airbox lid filter & snorkel. You can reinstall the snorkel, filter & lid once you get the box bolted in. It would be much easier with the MAF mounting flange sawed off, but I like the larger MAF tube & works great with a 996 reflash

Pro,

So there is no way to get the box in with the MAF flange and clips still intact? I had planned on keeping these for a stock installation appearnce. What about lowering the front of the engine al la front mount change?

What sort of pumbing did you end up with from the end of the 987 MAF housing to the the TB? I have a 997 diverter tee and this intake tract route was a real pain last itme around....having no garage I cant linger, hum and haw with fabrication so just asking

I am using the 987 Maf tube mounted to the airbox flange with the oem o-ring seal & clips. The flange is what makes it hard to install the airbox past the oil heat exchanger. Once you get the box bolted in you can install the MAF tube. Hard to see in this pic, but the widest clamp to the right is clamping the hose to the MAF tube:

Thanks, yes I see it. It looks like you are using the stock 987 rubber piece at the MAF housing.

Yes I wouldn't try it with the MAF tube on....so not possible with clips and flange?

I dont plan to saw off anything but the muffler

dude - he didn't remove the flange.

Yes but it's a 3.6 so presumably the engine came out to put the flanged airbox in....may not work with the 3.2 sitting there....or it's simply a matter of removing the oil cooler

Need the detail so I can bang out the job in a day when the opportunity arises

My Box has the original engine that I rebuilt 2 years ago & now displaces 3.6L. In a previous post I was giving RadiumKing tips on how to install airbox with engine in place by removing half the intake manifold with fuel rail.
