The Laser 6953 specifically caters for the Ecoboost range up to the 2.0 litre version, & is designed & manufactured by Laser in Sheffield. The machined split collet design fits over the injector securely & allows the use of a slide hammer (included in the kit) to steadily pull out the injector. Simple to use, the slim design fits down over the injector & the body of the tool is turned to securely grip the injector. The weight of the slide hammer has been carefully calculated to ensure the correct shock level is used for injector removal.
