Anyone here tried these? I'm interested in staying with the stock engine, but want to play with the setup a little. HAve a friend at the dealer who's a master tech, and he said he had both on his and was really happy with them. That was a 2F engine tho (and he does have a V8 now ). So if anyone's tried these, let me know if they're worth the $$ or not.
