So I bought the silicone intercooler piping kit from flying Miata. It fits beautifully. Except it doesn't fit my intercooler. I was willing to buy their intercooler to make life easy but they're out of stock and nobody knows when they're coming back in. I can't seem to find another intercooler with the dimensions they are using for the shape. Anybody got any ideas?

 

You don't need the exact size intercooler. Best thing about their piping kit is that you can cut it to length.
I've used the Vibrant 12800 with their piping kit (and amazed how it almost doubled in price since 2019 ~).
Arguably the best intercooler for the money.

 

That IC piping worked well with my fab9 Stage 2 intercooler. I had to slightly modify it, but it worked. You could go through my build thread and find when I installed it last spring if you are curious.
