Precision Works CTS-V ZL1 6.2L LSA 機械增壓冷卻液管路 -12AN 轉接頭

The -12AN threads cut perfectly into the factory LSA coolant ports, and the included o-rings sealed up tight on the first try. Took maybe 20 minutes to swap the old rubber hoses out for these billet adapters, and now my engine bay looks clean as hell.

I was a little worried about fitment, but these adapters sealed perfectly with no leaks after I torqued them down. The -12AN threads were machined cleanly and made swapping out the stock rubber lines straightforward.

These -12AN adapters threaded right onto my CTS-V's LSA supercharger without any chasing or filing, which I was half expecting to deal with. No leaks after a few heat cycles and the coolant temps have stayed steady. Finally ditched the factory rubber lines for good.
