Figures have shown that glow plug sales can more than quadruple over the

winter and Blue Print's Complete Glow Plug Solution range contains over 150 glow plug references, which cover more than 1,700 Asian & American applications and are all covered by a 3 Year Unlimited Mileage Warranty.
Obviously, the first thing to do when changing a set of glow plugs is to remove the old set, and depending on their location, this can throw up access issues – to combat this, Blue Print now supplies 8, 10 and 12mm, glow plug Sockets.

Aside from their location, glow plugs can be difficult to remove due to a build-up of carbon in the aperture, which in the most extreme cases, can cause the tips to break off and be left in the head. In addition, glow plugs fail prematurely from being overheated from the inside out (relay constantly on), or outside in (carbon build-up around the plug tip), which is what happens over 90% of the time.

Because of this, the apertures must be cleaned on every glow plug replacement in order to avoid premature failure issues, or subsequent removal problems. For this, Blue Print now supplies a glow plug aperture cleaner, which is suitable for engines that use M10 x 1 and M10 x 1.25 threaded glow plugs and is essential for a professional and long lasting replacement.  

Once this simple process is complete, the new Blue Print glow plugs can be fitted using the applicable socket and Blue Print’s drive, 5>25Nm Low Torque Wrench. The torque wrench is perfect for all low torque requirements, including glow plugs, which removes the possibility of over tightening which is another common cause of failure.
