Intake System

engine, the combination of this intake system, our header, our Power Pulse Presilencer, and our Prima Flow Muffler boosted the peak power from a stock135 to 177 HP! This kit includes all the hardware necessary to install the system on a Mazda automobile, including metering oil pump linkage,vacuum source for the brake power assist unit, and cruise control connections, but eliminates all emission control fittings. Throttle response and driveability are outstanding, and gas mileage is approximately equal to stock for equivalent driving. The intake system comes completely assembled to help assure quick, easy installation.

Note: The stock GSL-SE fuel pump ismuch too powerful for safe adaptationto a carburetor. We recommend (2) Facet fuel pumps (2 of Part No. 16587) to adequately supply the Dellorto system.

Note: The use of this system requires the use of a header system for proper results.
