AFE Intake for 05 4.4 question.. - Page 2

I would bet that from the factory these 4.4's come in a lil piggy(rich) and increasing the airflow will lean it out somewhat, but I still doubt that the pcm could not handle. Now if your totally took off the filter you might have been stuck in a lean postion. In my C5 Corvette I had to richen up when I used a Halltech TRAP intake. But the C5 OEM intake is very restrictive and the Halltech opens up a floodgate of air.
To take advantage of all the mods it is always best to dyno tune your pcm. However, I do not know of any software for the x5 that allows you to do that. Something ls1edit or hptuner would begreat for the x5.

so you think getting the AFE intake is ok for the engine and it would adapt to it?

yup.. the amount of air you can ingest is really limited by your MAF. you won't even come close to pushing even couple a/r pts.. best way to tell.. throw it on a dyno... the E39 m5/E46 M3 guys are having a dyno meet tomorrow.. Edge motorworks is having a dyno night in 2 weeks..

As for pics of the intake I do not.. basically a K&N mounted on an AL tube to a hose adaptor to the MAF. It also had metal plate blocking off the intake from the rest of the engine bay that my friend fab'ed for me.
