BILLION High-Pressure Radiator Cap (B TYPE)

We love Billion products here at the shop so I decided to bring some extra Billion radiator caps home to spread the goodness to North America. These radiator caps increase the valve opening pressure to 127kPa, improving the boiling point of the coolant and maximizing the cooling performance by 120% (which is what the website states). I am merely selling them as collector's items so please use at your own discretion.

There are two types of radiator caps for our cars so please make sure you look at your cap or figure out what radiator you have to make sure it fits. THERE ARE NO RETURNS OR EXCHANGES. I don't have enough inventory to be able to exchange if you get the wrong one!

Make sure you have either Type A or B!

A Type: Features rounded tabs (wings) on the side and is typically designed to fit older models or many aftermarket aluminum radiators like Koyorad, Mishimoto, etc. A type usually has a larger base/taller nipple.

B Type: Features square tabs (wings) on the side and is typically standard for OEM Honda factory radiators or OEM-style radiators. Some aftermarket radiators do use this type because they use OEM-style water necks. Please make sure to look at the bottom of your cap to see which style you need. B type usually has a narrower, shorter nipple.

Again, please make sure which style you need before you order!
