Key Features

• Part number 12665 distributor mounting gasket
• 1 9/16-inch outside diameter
• Application-specific sealing material for distributor base service
• Fits many Chevrolet C10, Camaro, and Impala applications
• Also used on select GMC, Pontiac, Oldsmobile, Buick, and Jeep models

Detailed Description

Fel-Pro 12665 is a distributor mounting gasket engineered for vehicles that use a 1-9/16-inch outside diameter seal at the distributor base. Fel-Pro gaskets are known for vehicle-specific sealing solutions, and this part follows that approach with a fitment-focused design for older GM trucks, vans, passenger cars, and select Jeep models. If you are servicing a Chevrolet Camaro, Chevrolet Impala, or GMC Jimmy, this gasket provides the correct sealing interface for the distributor mounting area.

This part cross-references MAHLE B26466 for the same application.

What It Helps Address

• Oil seepage around the distributor mounting area
• Loss of sealing at the distributor base
• Improper gasket sizing during distributor service
• Maintenance on aging ignition and sealing systems
• Replacement during distributor removal or reinstallation

Installation Notes and Tips

Confirm the distributor base uses a 1 9/16-inch outside diameter gasket before installation. Clean the mounting surfaces thoroughly, remove old gasket material, and verify distributor seating before tightening. For best results, match the part to the exact year, make, and model listed in the fitment data, including Chevrolet C10, GMC P3500, and Pontiac Firebird applications where specified.

Quality Assurance

Fel-Pro states that its gaskets are built for complete vehicle sealing using application-specific materials trusted by professionals. Part number 12665 is backed by that sealing-focused product approach for service on compatible Chevrolet, GMC, Pontiac, Buick, Oldsmobile, and Jeep vehicles.
