Air to air intercooler mounted on ea839 2.9tt

Air to air intercooler.

Spotted this interesting build on FB, a french RS4 with a wagner FMIC likely from a S4.

Could be a great alternative to the air to water system, maybe someone could make a kit with the y charge pipe from the turbos.

What’s the advantage of air to air over air to water?

How much would it cost to convert the air to water system over to air to air?

It's expensive couple g's, I've had a different setup with a vertical vibrant core for the last year on my RS5. The passenger side piping couldn't move through cleanly due to the extra radiators. So mine is channeled through the left side. Granted I also got my twin intake re-fabbed in metal and had the piping all squared for methanol. In the long run, much likely cheaper for you to get the Wagner.

That's what I figured. An air to air set up is easier and cheaper to upgrade but only if it came like that from the factory. The actual conversion process negates any potential cost savings.

There are trade-offs between air-to-air and air-to-water. Here are a few viewpoints:
