Important! Read all instructions before you begin installation.

Place the Street & Performance Electronics Helix Power Tower with the new gaskets in between the throttle body and the intake plenum. Secure with the new longer bolts supplied with this kit. Torque the assembly to 15 ft/lbs.

6.       Install the throttle linkage extender plate to plenum (original stock location) with OE bolt. Please make sure the roll pin of the plate is in locator hole on plenum. Reinstall the throttle linkage to the extender plate and use the supplied hardware to secure it to the new extender plate. Torque both bolts to 10 ft/lb.

7.       Install new vacuum line extender (black z-bend bracket) to original location with OE bolt and install vacuum line bracket to this extender with the supplied hardware. Torque both bolts to 8 ft/lb. (Note: it may be necessary to lengthen the linkage cable and vacuum line from the intake plenum anchor points)
