JDC Titanium Valve Cover Hardware Replacement Kit

This kit replaces the rusty OEM valve cover hardware with beautiful CNC machined Gr5 titanium hardware! The valve cover bolts are designed to match the OEM specs for depth and diameter, but we've added our custom-designed head for a cleaner, more flush look! This kit will work on the plastic, or aluminum valve covers. We have two options available for you to select from.

The full kit replaces all the valve cover hardware and also includes replacement hardware for your coils, wire harness brackets, and fuel rail line. The full kit includes:

(18) JDC custom head bolts with collar specifically designed for Evo X
(4) JDC Custom Head M6 bolts for coils
(2) JDC Custom Head M6 bolts for fuel rail line
(3) JDC Custom Head M6 bolts for valve cover brackets

Basic Kit:

The basic kit only includes the valve cover bolts themselves. The basic kit includes:

(18) JDC custom head bolts with collar specifically designed for Evo X

The recommended factory torque specs for the valve cover hardware is 48.5 +/- 4.5 INCH-POUNDS! Make sure to use a 4mm ALLEN KEY to torque the bolts and not a Torx bit. Our Evo X Valve Cover Bolts have been tested with a torque wrench to withstand 14.5 ft/lbs (174 in/lbs.) before the head strips. If you are having an issue with stripping bolts, you are doing something wrong.

Gloves are recommended during installation to keep oils off of the titanium. If you don't have a set of clean gloves, washing your hands before touching the titanium parts will help. After the installation, you can wipe down the hardware to bring back the shine using soapy water or Windex with a microfiber rag.

Step 1: Start by removing all the bolts from the valve cover except the bolts in holes 1 and 2 in the diagram below. These will help keep the valve cover centered while replacing the rest of the bolts. Insert the rest of the bolts and loosely hand-tighten them.

Step 2: Following the torque diagram below; torque all the bolts to 26.5 +/- 8.8-inch lbs. in the order shown. When you reach bolt 18, replace bolts 1 and 2 with the new bolts. Continue the torque sequence with bolt 3 to 48.5 +/- 4.5-inch lbs. Do not forget to do the final torque on bolts 1 and 2. If you ordered a basic kit, you can stop here. If you ordered the full kit, proceed to step 3.

Step 3: The 4 medium-sized bolts (M6x20mm) are for the coil packs. Remove the old bolts and replace them with the new titanium bolts. Hand tight will be fine those these.

Step 4: Remove the 3 old bolts from the wire clips on top of the valve cover. This will require pinching the black clip and removing it from the bracket to get the 10mm socket on the bolt. Replace these with the smallest bolts (M6x12mm). Hand tight is fine for these.

Step 5: Remove the two bolts from the top of the fuel rail and replace them with the small titanium bolts (M6x12mm). Hand-tight is fine for these as well.

Step 6: Take a step back and admire the beauty of a custom titanium valve cover kit from JD Customs USA. Don't forget to take a few pictures and tag us @JD_Customs_USA! We usually repost installation pictures on our Instagram story! Thanks for your business and stay tuned for more Evo X parts and kits coming soon!

GR5 Titanium (Grade 5 Titanium) is a premium alloy composed primarily of titanium, with small amounts of aluminum (6%) and vanadium (4%) for added strength and versatility. Renowned for its exceptional strength-to-weight ratio, GR5 Titanium offers superior corrosion resistance, excellent heat tolerance, and remarkable durability. This makes it an ideal material for aerospace, automotive, medical, and high-performance applications, where lightweight strength and longevity are critical.

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.
