The AAM Competition Throttle Body Spacer gives you many tuning options for your 350Z. Made from laser cut billet, this spacer has 3 pre tapped vacuum ports, so you no longer need to tap the plenum.
Because you have more vacuum ports available you can run components seperately (ie. map sensor, boost gauge, fuel pressure regulator, boost controller, etc.) which improves both their performance and reliability.
This will fit any VQ35DE engine (350Z, G35, Maxima, Altima). The kit includes, gasket, hardware, port plugs and 3 vacuum fittings.
