Default Dorman Manifold as good as LS6?

https://www.amazon.com/Dorman-615-90...ntake+manifold

Are these manifolds the same or like most Dorman's they just a stop gap part? Their Mustang GT replacement was not good.

Anyone have a read on them?

It's an aftermarket repro, take that for what it's worth. Some dorman parts I've had have been ok, some have been worthless. For just a little more, I'd probably hold off until a deal on a used legit LS6 pops up. I know there was a TB/Manifold combo for like $375 recently, and you could flip the TB and come out ahead most likely.

I have been totally unimpressed with Dorman and after the Jeep front CV shaft won't buy their products anymore. Lasted one year and one day before front boot ripped apart, exactly one day past warranty. Look for a used one, I think you will be much happier.

I have the 97. What about the Performance Product unit but saw that there is some issue with the throttle setup?

i would go stock if you want votes

i will use dorman on old 90s trucks, some connectors etc. even used a dorman exhaust manifold to repair an old jeep

would not use their stuff in performance applications. most i have seen is all overseas made copies. basically knock offs and sometimes that's okay. i just wouldn't do it here

I went with the Dorman LS6 Intake for my 2000 LS1
I just couldn't find any good used ones for sale under $500 this spring
when I bought it..
unfortunately life got in the way, and it's still new in box on my shelf.
Maybe this winter I can get time.
I plan on doing some "cleaning up" of it first

has anyone done any real world testing with these to see how they perform vs an oem ls6 intake?... I'm just curious how close they really are in comparison or if they are even any better than the ls1 intake and people are just assuming and it's the placebo effect taking place... one thing I would definitely do before installing it is sand down the awful writing on top of it and paint it
