Arrow Arm Motorsports 7" Intercooler review / unbox (latest Version)

Hey guys,
I few months ago I was a little skeptical about the ARM Motorsports 7 inch intercooler. But......
When I was ordering their down pipes (to be installed), I decided to ask them what was the deal with this whole bottle neck thing
on the cold side of the intercooler that I kept hearing about?
They stated that they had no idea and that there was no bottle neck.
I asked them and asked them again.
To make long story short. I decided to take a gamble and order the intercooler, along other products I was ordering that day.
Now that I have opened the box and installed the intercooler, I am happy with the choice I made.
I decided that it was good to put this information out there, for anyone who it thinking about buying their products and I ended up documenting it.
So far the fitment of the charge pipe, upgraded intercooler hoses and the 7 inch intercooler where on point. No issues at all.
Feel free to take a look.
And let me know what you think and what your experience has been.
Also feel free to subscribe, Would definitely appreciate the support

+1 Good fitment is great, but how does it perform? 😉

I have been monitoring the temps with Protool, but no logs yet.
I have to take care of a few more maintenance before tuning.
I'm planning to run MHD. With MHD I will definitely be able to get some logs.
So far temps don't change much after a few runs. But then again I'm still not tuned yet.
What would be the ideal way to test those temps?

Differential between ambient and intake temp. Say if it's 90° outside and your ic is working awesome it should show 98° under full boost, only an 8° rise in temp. That's just an example.

it's nice the product fits but the quality is visually noticeable...

Wish psp was still around or people went with other options.

How quick the intercooler recovers after a few pulls is important also.
I went with a different brand, however, if I was buying a IC again I would avoid any that use the factory connections like that. They seems to leak no matter what.
OP I hope you installed new Green (hot side) and black (cold side) rubber seals when you installed
