The Z1 plenum spacer is a great addition for anyone looking to do a quick simple modification to thier Z. Installation was easy and straight forward, able to complete with basic hand tools (ratchet and sockets ect). Most difficult part is re-installing the stock strut tower brace. My tip would be to remember to adjust the legnth of the strut bar prior to re-installing, you\'ll need to adjust for engine clearence even with addition of the supplied spacers. The end result is a stealthy mod that sounds slightly more deep and agressive. Used on my 05\' touring auto - feels more responsive and will definitly notice quicker acceleration past 3k rpm\'s. Great product and a great price! Would definitly buy again.
really high quality peace the best plenum spacer for the de hands down
shipping was very fast. very satisfied with my VQ35DE Plenum Spacer. will do business with you guys again
This is one of the most common modifications for the VQ35DE motor. I installed it on my 350z and I noticed a deeper engine sound at higher rpms especially at full throttle. I can also tell there is an increase in acceleration response above 3000 rpm. This was a simple install to do except adjusting the strut bar with the washers. Overall, I'm pleased with the results.
If you are reading all these reviews, it probably means you are on the fence about clicking the add to cart button... just go ahead and click it! I was also on the fence about ordering this for a very long time. I finally bit the bullet and ordered it... I should have done this YEARS ago. This is the best $170 dollars I have ever spent on my Z! You know how there's those mods you do where you think you maybe can feel a difference but you aren't sure? Well this isn't one... I instantly knew this made a huge difference in mid and top end HP and torque. It definitely feels much stronger. I'm not going to say it's some crazy power gain, but it is definitely noticeable. Just make sure you do the ECU reset. Also when installing be sure you don't pinch the rubber seal around the oil cap between the plenum and spacer, or you will have issues! This is a very simple and extremely satisfying mod to do for a small amount of cash. Once again, a other great product from Z1 motorsports that has put a big smile on my face!
Your product works way too well. I noticed immediate throttle response upon installing. I was shocked how well this mod works. Thank you z1, I am so thrilled! Also shout out to Z1 for including the instructions to install, youre the real MVPs.
