Increasing the volume of the space between the intake runner and throttle body improves engine performance. This is where the best throttle body spacer springs into action. So, do they really work?
If you are curious, the spacers direct the flow of air into the manifold or throttle. However, for a high-affinity rate, you need a top-rated throttle body spacer for the engine.
Is a Throttle Body Spacer Worth it or not??
For an engine to work correctly, there needs to be a correct ratio of air to oil. If your car isn’t working smoothly as last year, it is probably the low air intake. Your fuel usage will rise up to the rooftop. So, what to do now?
Well, a throttle just might solve the problem. For starters, the spacer expands the space between the throttle and the intake for a perfect air ratio.
After you use a throttle body spacer, you will get improved performance and low oil consumption. How great is that? Turns out, a proper throttle body spacer is worth every penny. Here are some benefits of using a throttle body spacer. Don’t miss out on it.
Torque Boost: An old engine with low torque is a pain in the neck. What if you could increase the torque by 25 ft lbs? Fun fact, attaching a spacer will do the trick. Just make sure you attach the right one for your engine.
Soothing Sound: Won’t it be nice to hear a soothing sound when you start your car? The more air your engine takes in, the better it sounds. If there is a whistle sound coming from the engine, you probably fixed the wrong body spacer.
Faster Engine Speed: Spacers increase torque, horsepower, and oil efficiency. So, don’t you think the overall speed will get a boost too? The best part of throttle body spacers is that you don’t have to use too much oil for it.
Increase in Horsepower: When you get enough air into the combustion chamber, your engine starts to feel energetic. Kinda like your stomach with a good combo of food and water. If your machine had 100 HP before, now it will become 120 hp in now time.
Low oil consumption: The problem with oil engine is, when you have too much oil flowing to the chamber, you will see a rise in oil demand. The only solution to the problem is to get the sweet point ratio of oil to air into the burning system. Turns out, a throttle body spacer let’s just the right percentage of air to mix with the flowing oil. So, you can say bye bye to excess oil consumption.
