Learn how to replace your Subaru's dipstick handle with a CNC-machined aluminum Billetworkz handle. Step-by-step guide with common mistakes to avoid.
Quick answer
Installing a Billetworkz dipstick handle on your Subaru is a straightforward DIY upgrade that takes about 10 minutes and requires no special tools beyond a pair of pliers.
Before you begin: choose the right handle
Billetworkz offers two options: the handle alone (for retrofitting your existing dipstick) or the handle with a pre-cut assembled dipstick. The handle-only version requires you to reuse your OEM cable and pay attention to which mounting hole you use — the top hole is for EJ motors, the bottom hole is for FA motors. The assembled dipstick option comes with a cable pre-cut to your Subaru model, making installation even simpler.
Both handles are CNC-machined from 6061 aluminum with an anodized finish for long-lasting color. You can choose from several handle colors to match your engine bay theme.
Step-by-step installation
- 1. Remove the old handle: Grip the old plastic handle with pliers and pull it off the dipstick cable. If it's stuck, twist gently while pulling. Do not yank on the cable itself — you could bend the dipstick tube. Checkpoint: Make sure the cable end is clean and free of debris before proceeding.
- 2. Choose the correct mounting hole: For Subaru EJ engines (most 2000s models), use the top hole on the new Billetworkz handle. For FA engines (2015+ WRX, 2018+ STI), use the bottom hole. Refer to your engine code if unsure. Common mistake: Using the wrong hole will cause the handle to sit crooked or not lock in place.
- 3. Install the new handle: Slide the handle onto the cable end until it seats firmly. The included O-ring should sit between the handle and the dipstick tube cap for a snug seal. Press down until you hear or feel it click into position. Checkpoint: Give the handle a gentle tug to confirm it's secure before closing the hood.
