the PSM mod, Cool Black Hose, Amsoil EAA Air Filter, and a TAG. Not sure if the TAG does anything, but it is in there and doesn't seem to be hurting anything. Overall it did everything is was supposed to do, lower EGT's in real road conditions, and help with spool up. It did both and still looks stock, which is cool if it ever had to go to the dealer for engine work. Scotty
I did about the same thing, even used the black hose to keep it looking as stock as possible. Sealed both intake snorkels very well so that ALL of the intake air is coming from the outside. Just haven't tried the TAG yet, because it is "up in the air" if it really improves spoolup or not.
Have tried several different setups, including some expensive ones and wish I had just done the PSM with the Amsoil in the beginning. My passenger & I can hardly detect a difference in in-cab intake noise also, like almost no change. Of course the silencer ring went back in the turbo.
One thing I consistantly notice is shutdown time is quick (I have this little routine of idling down the street, turn the corner and continue to coast up the driveway and shut it off as soon as hitting the driveway since the neighbor's bedroom window is next to the driveway). Have come in for this same "landing" for years and I can usually tell which intake is working best by how far I need to coast until it shows 300*. With the BHAF it needed a longer coast. With the PSM/Amsoil/Silencer Ring in combo, it's dropping through 300 when Im turning the corner and darn near down to 275 at shut down. The ONLY other air filter that did that was a giant cone-shaped AFE PG7 filter used BHAF style with a heat shield. Also just idling, its hard to keep the heat in the motor as it always wants to drop to 275 or less.
I understand there are people that are not sold on the outside air concept, and thats fine. First is it truly all outside air, or is some leaking in from under the hood, mine is totally sealed, all outside air, with a slight ram air effect from the bottom of the windshield pressure zone.
Also, with the a/c on or off, egt's don't seem to be effected much, and cool down time is as good or better than anything else I've tried.
Yep, sure like the stock appearance also. :-laf
