Best Rtv For Intake Manifold FAQs

Are there any special considerations for using RTV on an aluminum intake manifold?

Yes, there are some special considerations that you need to keep in mind when using RTV (Room Temperature Vulcanizing) on an aluminum intake manifold. RTV is a type of silicone sealant that is commonly used in automotive applications to seal gaps and prevent leaks.
