JDC Titanium A/C Cap Set

Add a subtle yet premium detail to your engine bay with the JDC Titanium A/C Cap Set. Designed to replace your factory A/C service caps, these precision-machined titanium caps deliver a clean, high-end look while offering long-term durability.

Each cap is CNC machined from a single piece of 6AL-4V Aerospace Grade titanium, ensuring exceptional strength while remaining extremely lightweight. Titanium also provides superior corrosion resistance compared to factory plastic or metal caps, maintaining its finish and integrity over time.

Every cap is hand-polished and finished using JDC’s proprietary anodizing process, producing vibrant, long-lasting colors that won’t fade, even under harsh engine bay conditions.

Looks Good

So unfortunately these do not fit the 22 WRX I had purchased them for. They would have completed the rest of the titanium JDcustoms set I have. Instead of sending them back I put them on my 16 WRX which they fit. To bad the 16 is my beater car so I don't have a need for them on it. But they still look good.

Excellent Detail in the Engine Bay

Confirmed fit for a 2015 Hyundai Veloster Turbo, and perfect little detail to complement any engine bay dressup project! Will anyone else notice? Maybe not... but the little details are what make *me* smile when I pop the hood, and that's all that matters.

Supra ac caps

They are very nice looking but only the big one fits the A90 3.0 Supra. Unfortunately the small one doesn't fit. It was worth a try though. Love all of the products they have and the quality is great.
