I had one on my mr2 with a trunk mount intercooler. It did add a little hp, but more importantly, one quick blast got rid off any built up heat soak form running it hard for extended periods of time. However, I woul never bother putting it on a front mount intercooler car which has plenty of airflow to keep it cool enough. Also, it runs out real quick cause it blasting a lot of nos at a time from a relatively small bottle.
