As for torque numbers, the JLT with a tune yields 30hp/32tq. The Airraid is about 35hp/30tq. The Steeda and BBK intakes are probably also in the same ballpark with regards to torque increase. But, to be honest, I wouldn't spend the extra $100-$150 when you can get a JLT or Airraid. Note, as for the hp/tq numbers, this is probably also with a very aggressive tune on a nice cold day.
