  • Volant throttlebody spacers are designed to provide additional performance with your factory or Volants Cool Air Intake system. Manufactured from glass-filled Nylon composite, the Vortice spacers are incredibly strong, yet lightweight and install behind your vehicles throttle body to promote quicker throttle response and in most applications, provide a slight improvement in fuel efficiency.

    Spacer and Air Intake are not compatible

    This throttle body spacer and air intake do not work together. I have a 1999 Chevrolet Silverado 4.8L, with zero modifications. As far as the throttle body spacer, the install went as well as it could have. I found the directions to be difficult to follow. And the only official video I found online was for a Ford. I ended up stripping the threads on one of the plastic spacers that came with the kit. I was torquing to a modest 8-10nm when the threads stripped. There were no torque specifications for the kit; I made a best guess. The spacer installed okay. I could have used a little more instruction when it came to removing the stud bolts from the throttle body. I’d never done this before and I ended up stripping the threads on two of the three bolts (before I figured out a 5/16 socket would work). Since I couldn’t use the spacer with the Volant air intake, I needed to reinstall these stud bolts. Luckily I was able to chase the threads with the original nuts. It’s a really nice looking spacer, it’s just a shame that it doesn’t fit when using in tandem with the air intake.

    Easy installation.

    Installation was fairly easy. Jury is out as to whether or not it has improved anything. Bought along with cold air intake.

    Was a bit of a pain to install due to water pump pipe for the coolant. Had to take the hose off of water pump to install. Besides that everything else was easy.

    Install compromised

    I haven't installed it yet because I have your Volant system in my truck. Problem is the throttle spacer is going to add an extra 1/2 inch or more to the throttle body. Now when you go back to install the intake tube you have two choices. Cut the tube or cut the fan shoud to fit.

    Price/Performance

    The price point is high for the little bit of performance gains. The quality of the product, and the easy to follow directions, made for a smooth install.
