Secret Garage has done it again with their Honda K20Z3 Throttle Body Spacer!
Think of this as a Nitrous Plate for your K20Z3 Throttle Body. This CNC-machined, T6061 Aluminum piece gives you the ability to neatly and securely install your nitrous jets immediately before your intake plenum.
The flange is only 3/4″ thick. If you choose to purchase the throttle body spacer kit; which includes a throttle body thermal gasket, the overall thickness will be 7/8″. The thermal gasket is 1/8″ thick.
The flange comes tapped with a 1/8″ port for your nitrous jets; absolutely no fabrication needed, this is a straight bolt-on affair.
$90.55 – $139.62
