Default Intake manifold replacement

Hi all! I searched the forum for similar threads and basically found what I was looking for I think. I just had some questions I wanted to get some people's opinions on and didnt want to bump a several year old thread.

This manifold here
HTML Code:
http://www.americanmuscle.com/pi-intake-manifold-9904gt.html
I believe is the one I found in an old thread and I was just wondering people's opinions on it compared to
HTML Code:
http://www.amazon.com/Dorman-615-175-Intake-Manifold/dp/B000CIXMIC
I have a basically stock '02. Its got exhaust and a cold air intake. Ive read that the dorman apparently has slightly smaller ports than the pi. Will I be able to notice any kinda difference performance wise?

One other question and I apologize if this is the wrong place to ask it but are there any members out there with an old one laying around thats in good shape that would be willing to part ways with it?

Anyways, thanks for anyones input!

People have reported a noticeable power loss with the Dorman unit, and also minor fitment issues. Given the experience I have with Dorman brand replacement parts from Autozone (thermostat housings that last a year, headlight switches that last 4-6 weeks and several others that escape me at the moment) and what is commonly known about their replacement manifold for these cars I steer clear of their parts every time now; complete garbage. Stick with the oem manifold.

I appreciate everyones opinions, it was a great help. I went with the OE one from americanmuscle.com. Hopefully it comes in monday or tuesday and I'll have her back on the road.

Cheers!!

Good luck dude. I've not had to do it but it doesn't look like a bad job at all, probably 2-3 hours including time to sip a beer and admire the finished product.

Be sure you have a torque wrench handy, and if you don't already have one then get a Haynes or Chilton manual for your car as it will walk you through the procedure including the all-important bolt torquing sequence.

Since they have raised the price of the Ford Racing intake for $35.00 bucks more you really have to consider the EDELBROCK VICTOR JR. EFI INTAKE MANIFOLD
DO YOURSELF A FAVOR DON’T BUT A USED ONE AND DON’T BUT THE DORMAN

For a mildly modified Mustang the edelbrock will be a bit to much IMO and can get really expensive really quick.

^^^^^ correct
unless you are running aftermarket heads, or ported stockers and/or forced induction, you will see almost no gain in power over the stock PI intake. so save the money for upgrades that will gain power, or save for that dream engine build
