To many, the throttle body gasket is one of the most trivial parts in a vehicle's engine. Little did they know that this small seal can make a lot of improvement on a car's performance. A well-performing throttle body gasket can increase a vehicle's fuel efficiency, power, and torque. On the other hand, a leaked throttle body gasket can cause a car to stall in the middle of a highway. If you have decided to buy a new gasket for your throttle body, the following information will prove to be useful in deciding to buy the perfect one for your car.
A perfect fit
Needless to say, each car model has a different and unique body throttle. The body throttle gasket is the seal the keeps outside air from entering the space between the intake manifold and the throttle body. It needs to be fitted perfectly between the openings of the two parts. A miniscule hole or leak can cause troubles in idling and even while running. To avoid such problems, get the exact shape and measurement of the entrance and exit between the intake manifold and the throttle gasket. Remember that the engine is one of the most important parts of your car and a small problem can snowball into unimaginable damages.
The correct width
The normal throttle body gasket width is 0.125". If you can see that there is still enough space to accommodate a thicker material, it is advisable to purchase a thicker gasket or even a throttle body spacer. A spacer works exactly like the throttle body gasket but is considerably thicker. This thickness allows extra air to pass through when the gas pedal is being pressed, allowing more power for the running engine. Just make sure you have a bolt that can fasten the gasket or spacer between the throttle body and the intake manifold.
Keeping it cool
Another important function of the throttle body gasket is that it keeps the heat of the engine from the reserved air in the body throttle. Though this, cooler air is being delivered to the intake manifold, making the combustion process better. Because of this function, it is very important that a throttle body gasket is made of materials that are able to insulate and resist heat. The same way, the material should be soft enough to be hugged and sandwiched between the intake manifold's and throttle body's openings without the smallest possible gap. Likely materials in the market are nitrile rubber and Teflon among others.
