Throttle Body Spacer Products

Allowing your engine to produce more power is a common goal of many performance engine parts. Add-ons such as cold air intakes and headers are designed to get more air into your cylinders, where the oxygen mixes with your fuel to produce power. This is the basic concept behind the throttle body spacer. The throttle body spacer goes in the fuel/air intake area of your engine, and can be installed in under an hour using common tools. For older vehicles with carburetors, this component simply increased the volume of the fuel/air mixture, or allowed for a more dispersed fuel spray, which could be burned more rapidly. Today, most vehicles use a fuel injection system. Modern throttle body spacers are designed to enlarge the air entry passageways and allow for a greater and more forceful amount of air. This means your engine does not have to work as hard to get air in, and lets that "found" power get used where you want it most: down to your wheels. The installation of a throttle body spacer can add up to 25 ft lbs of torque and up to 18 HP. In addition, the throttle body spacer improves your fuel economy and nets gains of up to 4 miles per gallon. Adding a throttle body spacer to your engine is a fast, inexpensive performance modification that will save you money on gas as it gives you more power. When you browse our extensive online catalogue and order a throttle body spacer through our secure online server or toll-free customer service number, we'll ship your performance part right to your door. It won't be long before you are enjoying an increase in engine power and performance.

What to Consider when Buying a New Throttle Body Spacer

With fuel prices going up, it's clear that fuel efficiency is the name of the game in the car industry. So how can you save on fuel without having to change to a hybrid or electrically-powered car? The answer lies within a 1-inch thick piece of metal known as the throttle body spacer. Here are a few things you have to remember when choosing the right throttle body spacer for your car.

Straight types vs. Vortex types

A throttle body spacer is an optional part of an air intake system. When installed, it changes the system's airflow by directing as much air to the air intake manifold. There are two types of throttle body spacers, which can be differentiated according to how it directs air into the manifold. The most commonly used spacers are those that direct air by straightening the airflow through the tubes of your intake system. Another type of spacers is the vortex-wind throttle spacers. Although most studies suggest that the swirling direction made by vortex spacers provides better combustion, air should travel about a meter long before any significant effects can be felt. Unless you have a massive engine, it's best to install straight-type spacers. They're relatively cheaper than vortex types and more effective on a normal-sized engine.

Throttle-body injection systems vs. Multi-point fuel injection systems

As mentioned above, the throttle body spacer is an aftermarket add-on to your intake system. With that said, the type of spacer you will purchase has to fit the rest of your manifold. Throttle-body injection (TBI) systems are more likely to benefit from a spacer than a multi-point fuel injection (MFI) system. The smaller diameter of a TFI system benefits from the additional plenum volume provided by the spacer, which gives the fuel more opportunity to vaporize. So if your car has a stock MFI intake manifold and you wish to improve fuel efficiency, adding a throttle bed spacer might not give you the horsepower and increased mileage you expect.

Research your way to the right TBS

When you're in the market for a new throttle body spacer, research is key. The kind of spacers you need will largely depend on the car you own and its engine type. If you purchase a throttle body spacer that doesn't fit your vehicle's specs, it can be ineffective and excruciatingly noisy. Go through trusted message boards and focus on different real-world accounts from drivers with a similar make, model, and engine as your car; see which kinds or brands of TBS they prefer. You can also scout for detailed reviews of TBS brands on different online sites. It's best to be informed before making your purchase to ensure you get the right throttle body spacer the first time around.

How to Install a Throttle Body Spacer

You've already cleaned your air filter and double-checked your engine. Nothing seems to be wrong except for the fact that you still haven't increased your gas mileage and engine power. If you can't get the performance and fuel efficiency that you want from your car, why not install a throttle body spacer instead? Here's our step-by-step guide to installing a throttle body spacer in your car.

Difficulty level: Easy to moderate

Things you'll need:

  • Throttle body spacer
  • Socket set
  • Socket wrench
  • New gaskets
  • Cleaning solution
  • Rags

Step 1: Open your car's hood to gain access to your engine's compartment and air intake system. Be sure to illuminate your workspace to give you more visibility as you work on your throttle body.

Step 2: Using an appropriately-sized socket wrench, detach the negative battery cable from the battery of your car. As a safety precaution, be sure to place your negative cable away from the battery so that it will not touch your car's battery while installing the throttle body spacer.

Step 3: Locate your air intake manifold, which should be connected to the opening of the throttle body. Once you've located the manifold, disconnect the air intake tube from the air filter and throttle body intake. You should also remove all vacuum lines and electrical cables attached to the tube.

Step 4: After removing the air intake tube, focus on the throttle body. Remove any bolts or accessories attached to the throttle body so that you can gain access to it. Unbolt the throttle body from the intake manifold and pull it away from the intake. Once removed, clean the surfaces of the assembly using clean rags and a cleaning solution.

Step 5: Insert the throttle body spacer on the opening of the intake manifold, placing two gaskets on each end of the spacer. Reinstall the throttle body to the manifold, connecting it to the other end of the spacer. Align the bolts in the throttle body, gaskets, spacers, and intake and screw them together.

Step 6: Reinstall any bolts or accessories removed in Step 4. Reattach the air intake tube, vacuum lines, electrical cables, and negative battery cable as well. Secure all parts in place.

Step 7: Once everything is bolted together and in place, you can now test your throttle body with your newly installed throttle body spacer.
