Great intercooler!

I installed this intercooler in my 1980 Volvo 242. The mounting points are nicely thought out, with steel threaded inserts already installed. The end tanks are sturdy and are shaped for great flow. The divider is a nice touch.

In the box was a treadstone T-shirt and license plate frame.

The only thing I would have liked to see is another threaded hole in the mounting bosses, but that isn't a big deal to add.

For the price, you can't beat this intercooler.
