How to Choose and Buy an Intake Plenum Gasket for Your Engine Block
Look at your engine and how it functions. It is a consolidated piece made up of different mechanical componentry. The variety of parts are welded, bolted or sealed to keep them intact. Even when pieced together, the parts can still have small gaps where particles can get into. This is bad for the entire system. Any foreign particle that ends up inside can compromise the performance and function of your engine. This goes the same for your intake system. The intake plenum gasket is inserted for this purpose. Here's how to choose one for your engine.
For unmodified vehicles, find a gasket set that is designed for your exact model
When you own an unmodified vehicle, it should be fairly easy for you to narrow down products that are compatible with the ride. All you have to do is to determine the year, brand, model and trim of the car and you are good to go. After your little research (if you actually need to do one), an expert can help you sort out the compatible products that are available in the inventory. It is fairly easy to do because providing and interpreting the necessary data is similar to inputting information to a decoding machine. From the details you have given, the type of engine powering your car can already be determined even if you do not know the exact model. This method works best for fairly new models because manufacturers continue producing OE-spec replacements for your car.
For vehicles that have gone engine swaps, you definitely need to know what motor is dropped in the bay
If you are involved in the auto modification scene, there are chances that you might have already swapped the original engine of your vehicle with a different block. This means that your power plan already has different specifications. You will not be able to nail down the correct gasket if you will only base your search on the vehicle model. To get the right part for your block, you will have to know the exact details about your engine. Is it a small block Chevy, a 5.0L Cayote, or a 426 Hemi? But we are guessing that you are pretty familiar with your Frankenstein of a hot rod build, aren't you?
Are you inclined more on performance applications or do you want to keep things unassuming?
Regardless of what engine you put in your vehicle, you will definitely need to determine how you are going to use your ride. For normal driving applications, you can make do with an OE-spec gasket. It is built to work and last for a good number of miles given that your journeys are only composed of going around the city and travelling highways. However, if you are inclined to go fast on the strip or on the track, you would have to use a gasket designed for performance. This is because the engine takes more stress when you push it to the limit to go fast.
