How much HP does a plenum spacer add?
They found that by increasing the volume of air passing into the intake plenum it could liberate increased horsepower and torque. An efficient way of taking advantage of this is by adding a spacer to the intake plenum. The intake plenum spacers in this guide have been dyno proven to yield up to 14 BHP.
Is a plenum spacer worth it?
The main reason why we recommend installing a plenum spacer is that the VQ35DE engine has a flaw in its plenum design. It cuts off a small amount of air to the intake runners which restricts airflow. Installing a plenum spacer is the best way to solve this issue and unlock that lost airflow.
Is Blox plenum spacer good?
The new material is intended to withstand the rigors of big boost turbo and supercharged engines that generate extreme intake, as well, as overall high engine temperatures. BLOX Racing’s plenum spacer is the industry’s best selling plenum spacer for the Nissan VQ35DE. Easy installation and 100% bolt-on performance.
How much HP does a plenum spacer add g35?
10 hp
0 features a number of improvements, including a thicker design that increases plenum volume, lowers intake temperatures, and allows the engine’s front cylinders to breathe more efficiently. “ “All of this results in gains as high as 10 hp, increased throttle response, and a fuel efficiency increase of more than 2mpg.
Do plenum spacers add power?
No matter the size, plenum spacers add more power to the engine, improve throttle response, and reduce fuel consumption.
How much HP does a throttle body spacer add?
18 more horsepower
With a throttle body spacer, it is possible to increase the torque by 25 ft lbs and add up to 18 more horsepower. Not all throttle body kits can be used for all engines. Ensure that you get a kit that will work for the make and model of your engine. These spacers mainly benefit older engines.
How does a throttle body spacer help?
The throttle body spacer permits more air than usual to go into the engine. Thus, the engine does not have to work as hard in order to get the correct amount of air into the combustion chamber. One of the main benefits of a throttle body spacer is an increase in horsepower.
How much HP does a plenum spacer give a 350z?
The Motordyne Basic spacer has a convenient benefit –– it comes with a pre-attached, high-quality gasket, making installation even easier. Installing it on your stock Nissan 350z, you can expect a 9-11 whp increase after installation, and a 14-17 whp increase on a turbocharged or supercharged 350z engine.
What is a plenum on a car?
Plenum is the part located between the front windshield and the bonnet of an automobile . It is primarily used as an air inlet to the HVAC during fresh air mode operation.
Do you need tune after throttle body spacer?
Throttle body spacers do not affect overall performance or delivery of air / fuel. Since these spacers have little bearing on performance, a tune is not required after installation.
How much HP does a cold air intake add?
5-20 horsepower
Cold Air Intakes are said to improve your vehicle’s performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn’t enough power to put you back in your seat, it will give your car or truck a little pep in its step.
Do throttle body spacers really add horsepower?
An additional test was run after removing the spacer, resulting in a return of the lost horsepower. Proving that some spacers can actually rob power from an engine. After seeing the results, it was clear that throttle body spacers were simply gimmicks and provided no real performance value.
Does throttle body spacer improve gas mileage?
A throttle body spacer is an easy bolt-on upgrade—it fits between the throttle body and the intake manifold. Most designs either speed up or impart a swirl action to incoming air to increase its velocity. That helps improve low and midrange power and fuel mileage.
What does a intake plenum spacer do?
Adding Horsepower To My 350Z With A Plenum Spacer – YouTube
Where is the plenum located?
The supply plenum is an air distribution box. It’s attached directly to the supply outlet of the HVAC equipment–that is, the outlet that releases chilled or heated air into your home.
What is the purpose of a plenum space?
A plenum space is a part of a building that can facilitate air circulation for heating and air conditioning systems, by providing pathways for either heated/conditioned or return airflows, usually at greater than atmospheric pressure.
What are the cons of a cold air intake?
The cold air intake does typically get denser air than the stock intake. However, since it is longer and more requires more complex routing, it is often more expensive. This increased complexity also leads to a more difficult and time-consuming installation.
What upgrades increase gas mileage?

- Cold-Air Intake.
- After-Cat Exhaust.
- Headers.
- Distributor Upgrade/Ignition Timing.
- Carburetor Swap.
- Intake Manifold.
- Ignition Coil/Plug Gap.
- Fuel Injection.
Do throttle body spacers make noise?
Next, be aware that some spacers cause a whistling noise. It can sound similar to a small turbo. Some people like this and some don’t. Other spacers are designed to be quiet.
Does an intake manifold spacer increase horsepower?
One of the main benefits of a throttle body spacer is an increase in horsepower. Ultimately, the spacer increases the air velocity which causes an increase in atomization.
Does plenum need to be replaced?
If your plenum box has failed, you may want to save some money by repairing or replacing it yourself. While the component doesn’t look complicated, if it’s not installed properly to allow proper air flow, your unit’s coils can freeze, the furnace can trip, and over time the compressor itself may malfunction.
Why do I need a plenum?
Article 800 of the National Electrical Code (NEC) states that plenum cable should ALWAYS be used in plenum airspaces and air ducts to slow down the spread of flames and reduce smoke and toxic fumes from circulating throughout the building.
How do you find plenum space?
A plenum ceiling is one that uses the space between the top of the suspended ceiling and the bottom of the floor above to handle air for ventilation. All suspended ceilings are not plenums; some may use HVAC ductwork to move air to returns and diffusers located in the ceiling tiles (a ‘dead’ ceiling).
