Why Upgrade Your Honda Prelude Radiator?

Older Honda Prelude cooling systems can become less efficient as factory radiators age, corrode or become internally restricted. Modified engines can also generate significantly more heat than the original cooling system was designed to handle.

The Mishimoto MMRAD-BB2-92 provides a performance-focused aluminium replacement designed to improve cooling efficiency while retaining straightforward installation and factory-style mounting.

It is an excellent cooling-system upgrade for Prelude owners carrying out engine modifications, restoration work or preventative maintenance.

The current Mishimoto specification lists a two-row, 2-inch core, 1.25-inch inlet/outlet, 2.39-gallon capacity and BB1/BB2 chassis compatibility.
