🔧 Install Tips
- Super Simple Swap: Twist your old plastic caps anti-clockwise to unscrew them from the lines, then twist your new NGK rubber caps on clockwise until they are snug.
- Keep Your Old Covers: Remember to reuse your old rubber dust covers on the ignition wire to add an extra layer of water protection right where the line meets the cap.
- Avoid WD40: Never spray standard WD40 onto electrical clips or wire ends. It leaves a wet film that can mess up signals. Use proper electrical contact cleaner or a wipe of ACF50 spray instead to keep out the damp.
