Description

MACE MANIFOLD PLENUM SPACER KIT TO SUIT NISSAN 350Z Z33 VQ35DE 3.5L V6Our plenum spacer sits between the plenum and plenum cover. Its main purpose is to improve air distribution between cylinders by slowing down the air speed inside the plenum chamber. As a result, there is less of a pressure drop inside the plenum chamber between cylinders and less air momentum. This, in turn, feeds each intake runner more evenly improving throttle response and bottom end torque. The change in airflow characteristics is shown in the

Our plenum spacer sits between the plenum and plenum cover. Its main purpose is to improve air distribution between cylinders by slowing down the air speed inside the plenum chamber. As a result, there is less of a pressure drop inside the plenum chamber between cylinders and less air momentum. This, in turn, feeds each intake runner more evenly improving throttle response and bottom end torque.

The change in airflow characteristics is shown in the diagram below.

 

 

Not only will our spacer help you make more power, it will also reduce air-fuel ratio variance between cylinders due to improved air distribution between cylinders. This is particularly important with engines running an aggressive tune or in boosted setups, as it reduces the likelihood of detonation.

As it is also manufactured from the same thermal resistant material as our manifold insulators, further horsepower gains and more consistent power output is achieved due to the reduction in air temperature.

 

Contents:

  • Manifold plenum spacer
  • Mounting hardware
  • Gasket maker

 

Key Benefits:

  • Provides better air distribution between cylinders
  • Produces a cooler charge air temperature
  • Improves low end torque by increasing plenum volume
  • Better fuel economy
  • Reusable over and over again
  • No undesirable side effects
  • DIY Installation

Vehicle Fitment Guide


Parts Guide

Please select the part number you require from the variation by utilising our vehicle fitment guide and parts guide.

Notes:
  • Installation is very straight forward, only requiring the removal of the plenum cover to install the plenum spacer.
  • The 8mm spacer is generally suited for vehicles running a factory or aftermarket strut brace. The 12mm spacer will have clearances issues with these setups. Due to variances between vehicles, it is important to check the clearance between the plenum and the strut brace before purchasing.

Fits like a glove, looks like a million!
Size: Small, Color: Purple
Bought this as a gift for him and very impressed. Looks like a million dollars, fit true to size, looks tailored not cheap. Fabric is quality, stitching is done well and the pants have a nice hidden elastic extender that helps if he goes up or down a few pounds. Very impressed!

It was the perfect suit for our big day!
Size: X-Small, Color: Purple, Size: X-Small, Color: Purple
Purple size xs. He's 5'9" 145-150lbs. Very impressed with this suit. The color and pattern is awesome. The fit was good. I would say this suit runs large. Usually he wears a Medium in everything but ordered an XS and it fit very well. The pants were long we had to get those hemmed. There was a few stray strings by the end of the night in areas of the suit. But overall good quality. And for a great price.

We were excited and I wanted to like it but...
Size: X-Small, Color: Black, Size: X-Small, Color: Black
We ordered this for Prom and it was supposed to be a size small, which was available for Prime ordering, but had to settle for xsmall. The pants, fortunately fit well and just need to be hemmed, the vest is great and the jacket is snug. My son has broad shoulders and I was hesitant to buy the xsmall, but it does fit just right. The only thing he would need to do is unbutton the jacket while he is dancing and maybe take it off while seated and eating dinner before prom. The material is surprisingly nice and has weight to it. I was relieved it isn't flimsy. The overall look on my son is smooth and we love the pattern and the material has shine to it. I was not happy that right out of the package, the button to the jacket could potentially fall off during because it doesn't look securely sewed in. The side of the right side of the jacket has thread already coming apart. And I found a little snag in a different location. I'm really not happy about that. I posted photos so you can see what I mean. We were excited about this suit, but it's going back. The company needs to do better with quality control.
