Intake Gaskets

Intake Gaskets: seal the manifold-to-head joint and keep your air-fuel path honest

An intake gasket sits between the intake manifold and the cylinder heads, sealing the runners and any coolant or vacuum passages that cross that joint. Its job is simple but critical: keep the manifold from pulling unmetered air past the seal. A leaking gasket gives you a lean idle, a vacuum leak that wanders your idle speed, and in coolant-passage designs a slow drip you can't trace. When you pull a manifold for a swap, a rebuild, or a cracked-gasket fix, you replace the intake gaskets rather than reuse them. That's the whole reason this category exists.

What ThreePiece stocks

There are 8 intake gaskets in stock right now from 2 brands: Cometic Gasket accounts for 7 of them, with Edelbrock supplying the rest. Current pricing runs from $23 to $56, which is the live range for what's on the shelf, not a standing promise. Five of the eight carry vehicle fitment data, covering Dodge, Ford and Chevrolet applications across a year span from 1955 to 2024. Named vehicles in that data include the Dodge Hemi, Ford Powerstroke, Chevrolet Small Block and Dodge Hellcat.

How to choose

Match the gasket to the engine, not just the make. A Cometic .060in fiber gasket for the 05+ 6.1L Hemi is a different part from the .060in AFM gasket for the 94-03 7.3L Powerstroke, even though both list a .060in thickness. Confirm your engine family and manifold style first. If you're running an aftermarket manifold, the Edelbrock Small Block Chevy gasket is the match for that platform. Thickness affects port alignment on some builds, so if you've been given a spec by your engine builder, buy to that number.

What else you need with it

An intake gasket rarely goes back on alone. If you're deep into the engine, look at Head Gaskets and complete Gasket Kits so you're not tearing back in for a second seal. While the manifold is off, it's a sensible time to check Fittings and Adapters on any vacuum or fuel lines you disturbed, and to inspect the Fuel Pumps feeding the system. All of these live under the broader Engine Components section alongside Pistons.
