I'm looking for a 58mm T/B especially ported, so if you don't use it, I can buy
In the other forum Shadow told me that a 58mm will be fine for my setup

me too:)

GLHNSLHT2, your T/B looks very nice but I can't do what you have done :clap:

Are this aftermarket neon TB "plug n play" for the sensors ?
Will a 58mm be enough ?
