Walbro electric in-tank fuel pumps are available in a variety of flow ratings, including pumps that flow significantly more fuel at higher pressure. The outside dimensions, however, of many pumps are compact enough to fit existing hanger assemblies, without modification. All pumping components have been validated to OEM specifications for use in E85/flex fuel applications. Most Walbro in-tank fuel pumps utilize a proven gerotor design. Some high-performance models, including those designed for engines with more than 750 hp, feature a dual-channel turbine design for maximum efficiency in high-pressure and high-temperature applications. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's higher than conventional pumps. Some pumps require modifications to system wiring, fuel lines, and the fuel module, and should be professionally installed. Installation kits including a fuel strainer, fuel hose, harness pigtail, clamps, and wire connectors are sold separately.

Airaid modular intake tubes optimize airflow to the engine by replacing inefficient originals. Factory tubes often have accordion-shaped walls, sound-canceling baffles, and undersized tube diameters that hurt airflow. The Airaid modular intake tubes help straighten and improve airflow to the engine, while also offering the best location for your mass air sensor. This design provides better throttle response, additional horsepower, and better fuel economy. These tubes are constructed from cross-linked, high-density polyethylene for strength and resistance to heat transfer. Airaid modular intake tubes are direct replacements for factory models, accommodating all sensors and fittings that attach to the factory tube. These tubes also work with the factory throttle body and intake box, and they include all necessary couplers and clamps for installation.

Automobile engines are a perfect balance of science and mechanical engineering. Each part is designed to interact with the other in perfect harmony to produce a means of transportation. One very small, but very vital component found in this mass orchestra of mechanics is the idle air control valve, or better known to mechanics as the IAC. Edelbrock offers their version, the GM stepper IAC motors, that also includes a valve gasket. The IAC valves adjust the airflow to improve motor idling. The gasket provides a tight seal to avoid a leaky throttle system, which could be a nuisance and also dangerous.
