A hairline crack in your 2018 Mustang GT intake manifold won't cause an engine failure. It might not even cause the check engine light to come on. Instead, you'll most likely notice it's cracked when you see your engine overheating, accelerating poorly, or leaking coolant. Sometimes people have no idea their intake manifold is damaged until they check the oil and notice that it looks milky. When they trace the coolant leak back to the source, they discover the crack.

The good news is, it's safe to drive with a leaky intake manifold and direct replacements are available. You can get a direct fit replacement as well that will mount up perfectly.

One of the things that causes intake manifolds to crack is heat and pressure. If you've been driving your 2018 Mustang GT hard, that's a likely candidate for the cause. To avoid cracking your new intake manifold, you'll want to look at ways of improving your engine's cooling. A cold air intake, larger radiator, or hood scoop may be the perfect solution.

We all love to drive our cars to their limit, but sometimes when you do, parts become damaged. Replacing these parts will help you avoid any long-term damage.
