After doing all of your free intake mods, I highly recommend starting off with this coil as your first bolt on. I haven't done alot to my LB9, but the air foil, K&N air filters, and the Edelbrock cat-back exhaust didn't all add up to what I got from this thing. Where you really feel it is when the rpms get over 4000. TPIs tend to fall on their face at this point but the coil definetly made a good improvement in this area.
