L98 TPI Throttle Body Coolant By-Pass
I'm by-passing my coolant through my throttle body and needing info if anyone knows of any business that provides block out plates to use in place of the coolant by-pass connector to the throttle body. All considerations will be truly appreciated.
Thanks.
Thanks.

hundreds of threads on this...

just fill them, no need for a whole plate.

No need for block off plates. I did the same bypass and just got some rubber caps from Autozone. They fit perfect. You dont even need clamps to hold them on. $2 and they've got them in stock.

vetteoz,
Nice job. Have you thought about filling the passages to make it smoother looking?
