Dorman Pentastar intake manifold screws 32128 — direct-fit replacement bolts, corrosion-resistant

Dorman 32128 Pentastar intake manifold screws are direct-fit replacement bolts engineered to restore the original fit and clamping strength for compatible Pentastar V6 intake manifolds.

If an intake manifold bolt has failed, become corroded, or is missing after service, installing the correct fastener is essential for a secure seal and correct component alignment. The Dorman 32128 screw is manufactured to match the dimensions and performance characteristics of the factory part for the specified years, makes and models, offering a reliable option when the original hardware can no longer be used.

How do these Dorman intake manifold screws match the factory parts?

The 32128 screws are produced to meet the form, fit, and function of the original Pentastar intake manifold fasteners. Dimensional accuracy and thread engagement are engineered to align with OEM mounting points so the manifold sits and seals as intended.

• Exact thread size and pitch designed for specified Pentastar engines
• Length and head profile replicate factory geometry
• Material selection for comparable strength and fatigue resistance
• Manufactured with consistent tolerances for repeatable fit

What material and durability features does the Dorman 32128 offer?

These screws are made from quality metal alloys selected to withstand engine bay conditions, torque requirements, and thermal cycling. While they are not a performance upgrade, the construction focuses on long-term durability and corrosion resistance for maintenance and repair applications.

• Corrosion-resistant finish suitable for engine environments
• Engineered to resist fatigue from repeated thermal expansion
• Manufacturing controls to ensure consistent mechanical properties
• Backed by Dorman product expertise and automotive experience

How do I confirm this screw fits my vehicle?

Use the vehicle selector or garage tool supplied on the product page to verify confirmed fitment for year, make, and model. If an information icon appears, hover or click it to read any fitment notes that could affect compatibility.

• Enter vehicle year, make, and model in the garage tool
• Check the Confirmed Fit bar at the top of the page
• Review any additional notes behind the blue “i” icon
• Compare part dimensions to your original bolt if needed

When should I replace intake manifold screws during service?

Replace screws any time they show signs of corrosion, stripped threads, head damage, or when the original fasteners are missing. During manifold removal for gasket replacement or repairs, swapping in new, correct-spec fasteners is a low-cost step to help ensure a proper reassembly.

• Replace if threads are damaged or torque cannot be achieved
• Swap out corroded or pitted bolts to prevent future leaks
• Install new screws after manifold or gasket replacement
• Use OEM-spec fasteners when reassembling engine components

Who is this for: The Dorman 32128 Pentastar intake manifold screws are intended for mechanics, DIY enthusiasts, and fleet technicians who need an exact-fit replacement fastener for Pentastar V6 intake manifold repairs. If you require a like-for-like bolt to restore factory fit and clamping reliability after service or failure, these screws provide a durable, readily available option with fitment verification tools to confirm compatibility before purchase.
