JDC Titanium V1 Oil Cap | Mitsubishi Evo 1-9/DSM

Replace the factory oil cap with one of the original signature pieces from JDC Titanium. The JDC Titanium V1 Oil Cap is CNC-machined from a single piece of Ti6Al-4V aerospace-grade titanium and designed specifically around the factory Mitsubishi mounting system for a secure, precise fit.

Unlike multi-piece aftermarket oil caps, the V1 incorporates the lower locking collar directly into the titanium body. This eliminates the need for a separate screw or nut inside the valve cover while maintaining a strong, simple design.

Each cap uses an OEM Mitsubishi gasket to provide a tight seal, then is individually hand-polished and finished using JDC's proprietary cold-anodizing process. The center is precision laser-etched with the JDC logo for a clean finishing touch to your engine bay.

Features

  • CNC machined from a single piece of Ti6Al-4V aerospace-grade titanium
  • Designed as a direct replacement for the factory oil cap
  • Uses an OEM Mitsubishi sealing gasket
  • Integrated bottom locking collar
  • No separate screw or nut inside the valve cover
  • Individually hand-polished
  • JDC proprietary cold-anodized finish
  • Multiple titanium color options available
  • Precision laser-etched logo

Installation Notes

  • The V1 Oil Cap uses an OEM Mitsubishi gasket and a tightly fitting locking design to create a secure seal against the valve cover. 
  • Each oil cap also includes a thin supplemental gasket to help achieve a proper seal on older valve covers where the sealing surface may have worn over time. If the OEM Mitsubishi gasket seals correctly, the additional gasket is not needed. If the cap does not seal completely, install the thin gasket together with the OEM gasket to help create a secure, leak-free seal. The thinner gasket should be installed in the cap first, and the OEM gasket should be installed on top of it.
  • A new OEM gasket may initially be firmer than one that has gone through repeated engine heat cycles. Because of this, the cap can sometimes feel difficult to rotate completely into its final position when first installed. If this occurs, applying a small amount of clean engine oil to the bottom of the gasket can also help during initial installation.

Made to Order

JDC Titanium products are colored to order unless otherwise noted. Each V1 Oil Cap is individually finished, anodized, inspected, and prepared for your order.

Please refer to the current production-time notice at the top of our website for the latest estimated turnaround time. Production time can vary depending on order size, selected finish, and other custom options.

Titanium Colors & Care

The JDC logo will be straight facing the front of the engine bay when tightened all the way. Adding a little oil to the bottom of the seal may also help. This tight lock provides a leak-free seal from day one that will last many years!

Please note that in some cases, the new seal may not have as much flexibility as one that has gone through heat cycles. This can cause the cap to be difficult to turn all the way. If you experience this issue, we recommend tightening the cap as much as possible without using excessive force. As the seal becomes warm and softer over time, it should allow you to tighten the cap the rest of the way.

Orders Containing Titanium

Colored Titanium:

  • All titanium is colored to order unless otherwise stated on the item listing. Please see the banner at the top of the website for the current estimated lead times. Production time can vary depending on your order size, products ordered, and the difficulty of custom options requested.

Bare Titanium/Stainless Steel:

  • In-stock items have a processing time of 3-5 business days.

For orders without titanium, our average processing time is 2-4 business days.

The one-piece design eliminates the possibility of the screw/nut falling off inside your valve cover, preventing a possible disaster! 

OEM Mitsubishi gasket is used for a tight and long-lasting seal.

How Do I Keep My Titanium Products Looking Brand New?

Installing: Wear gloves when installing titanium parts to prevent oils from your hands causing a "faded" look. After installation, clean the part before applying heat to avoid baking oils onto the surface.

Cleaning: Use our JDC Titanium Cleaner, designed to safely clean titanium without damaging the finish. Alternatively, clean with soapy water, a microfiber towel, or Windex, rubbing alcohol, or Clorox wipes.

Avoid: Harsh chemicals like water spot remover, engine degreaser, brake cleaner, metal polish, or acidic cleaners—they can damage the oxidized layer and remove the color.

Tip: Always clean when parts are cool to avoid water spots or tarnished finishes.
