The Edelbrock Q-Jet 3/4" wood-fiber spacer improves low‑RPM torque and throttle response while dampening reversion effects on the carburetor. Made from heat‑insulating wood fiber laminate, the 3/4" spacer reduces heat transfer from the intake to the carb and ships with the hardware needed for installation. The market notes a related 1/4" heat insulator kit for Edelbrock 94 and Stromberg 97 three‑bolt carbs.
