"Right after the install (which only took about 30 minutes) I drove into town and noticed I was getting close to 20 mpg on the freeway! Slight whistling sound was coming from my engine but it is just how the air is flowing through the spacer. Sounds almost like diesel. Very happy with the results and the engine sounds and performs more aggressive. Thanks AutoAnything" —Scott D from Elk Grove, CA bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2011 Honda Civic, 5.4L V8.
