Upgrade the look of the plastic factory coolant overflow reservoir tank cap with our CNC machined billet aluminum cover. Each cap is machined in the USA from a solid block of billet aluminum, engraved with the BMS logo, and anodized red, blue, or black for protection.
This cover will fit most 2018+ Kia/Hyundai/Genesis vehicles equipped with the same coolant overflow reservoir/recovery tank shown in the picture below. This is not a full cap replacement. The Billet Cap Cover affixes to the top of your factory cap.
🔧 Install: Peel high temp double sided tape. Press the cap on hard all the way down until it's a tight fit over the factory cap. No black from the factory cap should be showing. This cap uses pressure to stay on with extra reinforcement from the double-sided tape.
