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.

No there isn't. I've never seen a thread about coolant by-pass block off plates. Some people want a cleaner look. TPIS makes one.

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.

Yes, we all know that. But it is not as clean looking as the block off.

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