If you are talking about cold air intakes, check the addy in my sig. I have the MAC one for SD cars, but they are about the same. Made a little difference in my car, namely throttle response and a little more power in high RPM. good luck.
It's not out yet.....There is a picture of the lower in their new catalog. It sorta looks like a Trick Flow lower, but the runners are longer and staggered a bit more.
I talked to a guy who works at Brothers and he said it is going to outflow TF, and Edelbrock intakes, but sell for that price. He also said the fuel rails are set up for nitrous and it should be out in or near January possibly February
