Product Overview
Upgrade the cooling performance of your fourth-generation Honda Prelude with the Mishimoto Performance Aluminium Radiator MMRAD-BB2-92.
Designed as a direct-fit performance replacement for the factory radiator, this Mishimoto radiator is suitable for selected 1992-1996 Honda Prelude 2.2 VTEC and 2.3-litre models, including the popular BB1 and BB2 chassis.
Constructed from high-quality aluminium with durable TIG-welded end tanks and a substantial 2-inch-thick brazed aluminium core, the radiator is engineered to provide improved heat dissipation and cooling efficiency compared with a conventional ageing factory radiator.
Whether your Prelude is a road car, modified fast-road build or regularly used for demanding performance driving, upgrading the cooling system can help maintain more consistent coolant temperatures and reduce the risk of overheating.

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.
