Anyone heard of GT Pro?

These spacers were all the rage years ago. But when everyone over time ended up having issues with boost leaks etc. everyone ditched them. I guess they still get sold to suckers who don't know any better, but really, they do nothing. Like Jet said, the air doesn't spend enough time in the IM to make a difference in IAT's.

If a crappy intercooler can't make a big difference with temperatures, how is an open void with no turbulence going to have an effect?
