Here are some of the most noticeable advantages when using a plenum spacer on a Nissan z:. The two most popular materials used to manufacture plenum spacers are aluminum and thermo-polymer.
While both of them work perfectly fine, it helps to know which is better before you put your money down. So which one should you choose? Note: The exception to this rule is when combining a spacer with forced induction. No matter the size, plenum spacers add more power to the engine, improve throttle response, and reduce fuel consumption. What makes it stand out is its unique thermopolymer construction.
Compared to aluminum spacers, the thermal insulation characteristics of thermopolymer are much better, resulting in lower air temperatures — leading to a higher power increase. Owing to its thicker design, it is able to increase the volume of the plenum chamber resulting in more air for the front cylinders.
With all these great features, the power of your stock engine can be increased by up to 8. BLOX Racing makes the cheapest plenum spacer for z owners without any sacrifice in quality and material selection.

Overall, the kit is a reliable unit at a reasonable price and is the best choice for those looking to increase power without spending a lot. Keep in mind that this plenum spacer requires a modified top plenum gasket, but the great thing is that it is included in the kit. To get that extra horsepower, you pay for it in torque.
BLOX Racing claim improved power, torque and throttle response however they do not offer specific dyno numbers to back this up. After reading reviews online the quality appears to be hit and miss, some owners have raved about the BLOX Racing spacer while offers have complained of poor fitment especially with bolt hole placements on the spacer.
Our comment: The Motordyne product is the most expensive and best performing intake plenum spacer in our line up. Motordyne justify the price tag with an impressive power increase claim of BHP. This premium stealth modification adds 12HPHP and reduces the effect of power robbing heat soak. This plenum spacer can be used for maximum performance enhancement.
It also adds a substantially deeper growl under the hood. With the engine cover in place the engine bay looks completely stock with the only difference being the strut bar is not installed. Use the copper if it ever snows in your area.
So which spacer would we buy if it was our cash? We would choose the Skunk2 V2 intake plenum spacer as our winner due to the hefty dyno-backed performance increase, affordable price point and the quality Skunk2 brand that underpins this product.
