JLM J04210 Shock Spray: The Professional Injector & Spark Plug Loosener
Don't risk snapping a seized component. The JLM Injector and Spark Plug Loosener is a professional-grade technical spray designed to free the most stubborn engine parts. Whether you’re dealing with heavily corroded fuel injectors, glow plugs, or spark plugs, this "rust shock" formula provides a safe, chemical alternative to the excessive physical force that often leads to costly cylinder head repairs.
Using advanced Cold Shock Technology, this spray is engineered to tackle the unique bonding of carbon, rust, and gumming found in modern diesel and petrol engines.
Advanced Performance Features
- -40°C Cold Shock Effect: Upon application, the spray rapidly chills the target area to -40°C. This extreme temperature drop causes the metal to contract, creating micro-cracks in the rust and corrosion layers to break the fused bond.
- High-Penetration PTFE Lubrication: Once the bond is cracked, the formula's PTFE-based lubricant penetrates deep into the threads, significantly reducing friction and allowing for a much smoother extraction.
- Dissolves Engine Deposits: Specially formulated to eat through carbon build-up, oil residue, dirt crusts, and gumming - common culprits in seized injectors and glow plugs.
- Anti-Corrosion Protection: Leaves behind a durable, protective film that prevents future oxidation on exposed threads until the new component is fitted.
- Safe & Silicone-Free: The acid-free and silicone-free composition ensures it is safe for use on delicate engine components and won't interfere with sensitive sensors.
How to Use for Best Results
- Preparation: Clean the area with a wire brush to remove loose dirt and corrosion flakes.
- Agitate: Shake the can vigorously for at least two minutes to ensure the formula is fully mixed.
- Apply: Spray directly onto the base of the component from a short distance until the "frost" effect is visible.
- Penetrate: Allow a few minutes for the cold shock to work and the lubricant to seep in.
- Extract: Use appropriate tools to apply torque. Hint: Gently turning the component in both clockwise and anti-clockwise directions helps work the lubricant into the threads.
