The CZP 75MM Throttle Body Adapter Kit allows the Hitachi ETB0021 75mm throttle body to be bolted up to the stock upper plenum intake manifold. Our unique 2-piece design bracket allows the throttle body to sit straight and level like OEM, preventing any part of the throttle body from coming into contact with the hood, even if you have a plenum spacer. Our kit also utilizes O-Rings to create a strong seal, rather than flat OEM-style gaskets.
This Kit Includes:
- Hitachi ETB0021 75MM Throttle Body
- CZP Straight 75mm Throttle Body Adapter with hardware and O-rings
- CZP Plug-N-Play Throttle Body Patch Harness
Fits stock and Kinetix Velocity plenums. Will fit the V+ plenum with slight modification.
- Plug and Plug, no Tuning Required
- Continuous Angle Internal Bore for Enhanced Airflow
- Tapered Exterior for Improved Fit and Finish
- Black Hard Coat Anodized
Our new Compatibility checking feature is still being updated and revised. If you have questions about vehicle fitment, please contact us.
What is the slight modification required to install this throttle body on the Kinetix V+ plenum? Thanks!
Hi Bruce, with the V+ Plenum, there is one bolt on the perimeter of the plenum that interferes with one bolt head on the throttle body. The easiest solution would be to countersink the hole on the plenum and run a countersunk head bolt.
Hey, I was wondering if this would work with the Ingen CAI for the 04. It seems like the bolt down areas would change due to the spacers.
It still fits, there's enough margin of adjustment in the couplers. The trickiest part is you usually have to stretch the coupler pretty good to fit it over the throttle body.
Do I need to plug the water necks on the throttle body if Im installing on oem plenum?
You can leave them open. And in fact, we recommend removing them (they're just pressed in) to make installation easier.

plug and play . kit's been on my 04 Z33 for a few months without any issues or check engine lights . the adapter pates from Coz are top notch and the whole install was super easy . however on a completely stock engine you will probably not see any difference in power I would recommend this if your going to have plenty of supporting mods on your Z along with a good tune but if you have a faulty oem unit then get this kit .
Great quality product, I had one issue with the pigtail connector. But the great customer service, even with this covid stuff going on I was able to resolve quickly. I'm excited to hit the dyno and put this throttle body to work.
Hitachi does not screw around with the quality of products they offer - the adapter kit that CZP provides too is sleek, and well designed. Extremely easy to install, and works great! If you're running this on the VQ35 platform, be sure to tune it to get the full benefit of the product.
