Great kit, easy to install and well built. The adapter works as advertised and I'm happy with the performance upgrade. I will say that the throttle tends to hang open a bit more so the revs don't drop as fast between shifts, causing me to granny shift all over the place. I'm going to see if I can have my tuner work that out. Also for those wondering, no it is not required to use the coolant ports on the new throttle body, although if you really wanted to, I suppose it wouldn't be a bad idea.

Was going to order the NWP but I thought I’d give CZP 75mm throttle body a shot and let me tell you, This product works great! My butt dyno noticed a immediate difference.

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.

Seems to be what is described. Havent installed it yet gonna do it in the morning. Love the look of the czp spacer. Kinda mad I didnt get any like Hitachi or czp stickee..... But nice product

Ez install no problems

Easy install, not sure I feel the power gains yet though but it was straight forward. It would be nice if it came with caps to cap off the coolant lines though and an elbow to connect the coolant hoses together if not wanting to hook them the the throttle body
