The OEM J-plug is made of plastic, like many other components in your cooling system. This plastic becomes brittle over time and exposure to constant temperature change. Instead of installing another plastic piece that is bound to fail, ECS engineered a permanent solution; Our Billet Aluminum Coolant J-plug.
We started with the OEM piece to ensure we get all the critical dimensions just right. Machined 6061 aluminum for a strong yet lightweight plug that will not fatigue. And finally anodized our aluminum beauty to protect it against any future corrosion.
We've developed the strongest, longest-lasting, best looking solution on the market. Don't settle for just another cheap plastic plug that will breakdown over time causing you time and frustration.
