Kieth, I tried to install my MAF earlier using the stock box, while waiting for my new filter, but it doesn't fit w/ the stock box. Anyway, I started it up w/ the filter *basically* sitting right in front of the MAF, and it started up a-ok, no rough idle, nothing. But, I didn't rev it up more than 500 more RPM for fear of sucking something huge into my engine. Does yours idle ok?
Also, were you in on the GB for this MAF that I started in Feb? Just wondering.
