Detailed Description

Fel-Pro 60903 is a fuel injection throttle body mounting gasket engineered for direct sealing service on compatible Chevrolet and GMC applications, including models such as the Chevrolet C1500, S10, Astro, Blazer, and GMC K1500, Sonoma, and Safari. The gasket’s paper construction and premium grade help deliver a consistent seal at the throttle body mounting surface, where accurate fit and stable compression are important for maintaining proper intake sealing. This part number is also referenced in aftermarket catalogs under 60903 for straightforward identification during service work.

Fel-Pro’s sealing approach uses application-specific materials rather than a one-size-fits-all design, which is important when servicing GM throttle body injection systems across multiple body styles and engine bays. If you are replacing a throttle body gasket on a Chevrolet C1500 or GMC Sonoma, Fel-Pro 60903 provides the dimensional profile needed for the listed 3-bolt mounting pattern.

What It Helps Address

• Throttle body air leaks at the mounting surface
• Vacuum leaks that can affect idle quality
• Fuel injection sealing issues after throttle body service
• Gasket deterioration from age, heat, and compression
• Repeat sealing problems after intake or throttle body removal

Installation Notes and Tips

• Clean both mating surfaces thoroughly before installation.
• Inspect the throttle body and intake flange for warpage, corrosion, or residue.
• Match the gasket to the 3-bolt pattern and listed inside diameter before assembly.
• Follow the vehicle service manual for torque sequence and final tightening specifications.
• Verify fitment against the exact year, make, and model before ordering, especially on GM trucks, vans, and SUVs with similar throttle body layouts.

Fel-Pro gaskets are built around vehicle-specific sealing materials and are widely used in professional repair environments. Fel-Pro 60903 is manufactured to support dependable sealing performance on the listed Chevrolet and GMC applications, including 1985-1996 coverage across multiple models.
