Bowler - 8HP70 / 8HP75 Transmission Cooler Manifold -8AN

Aftermarket cooler line manifold for 8HP70 / 8HP75 transmissions. Converts to -8AN fittings for clean installs with aftermarket transmission coolers.

The Bowler 8HP70 / 8HP75 Transmission Cooler Manifold lets you convert your transmission to clean, flexible -8AN hose connections. It bolts directly to the transmission case.

This part exists because factory cooling lines were never designed for swaps, custom chassis, or performance builds. They’re awkward, hard to route, and they ruin an otherwise clean engine bay. Bowler built this manifold so builders can run proper aftermarket transmission coolers with -8AN lines—the right way.

What This Manifold Does

• Converts factory 8HP70 / 8HP75 cooler ports to -8AN fittings
• Eliminates factory hard cooling lines
• Allows use of flexible braided hose
• Makes swaps, restomods, and custom builds dramatically cleaner
• Improves serviceability and routing flexibility

Why Builders Choose Bowler

Bowler doesn’t make “universal” parts that kind of work. We build components that solve real problems builders run into every day.

This cooler manifold exists because:

• Swaps need flexibility
• Aftermarket coolers need AN lines
• Factory hard lines don’t belong in performance builds

If you’re already upgrading the transmission, cooling system, or engine bay, this is one of those parts you install once and never think about again.
