Using these K-Tuned throttle body heat shield gaskets is easy. First, make sure your engine is cool. Remove the old OEM gaskets from the intake manifold and throttle body. Then, carefully place the new K-Tuned gaskets in their place. Ensure they fit precisely. When it comes to maintenance, these gaskets are quite durable. But it's a good idea to check them periodically for any signs of wear or damage. If you notice any issues, replace them right away. And remember, since they're reusable, you can take them off and put them back on during your car's routine maintenance without having to buy new ones every time.
