Key Features

• PA6 glass-filled nylon construction for strength and heat resistance
• Black finish
• Gasket or seal included
• 9 mounting holes with 10 mm mounting hole diameter
• OE-style dimensions for direct replacement fitment
• Corrosion-resistant material designed for engine bay exposure
• Autotecnica GM1414325 cross-references Dorman OE Solutions 615-179 for the same application

Detailed Description

The Autotecnica GM1414325 intake manifold is engineered for the upper intake location on select GM platforms from 1993-1995. Its PA6 glass-filled nylon construction helps resist oil vapor and high engine temperatures while maintaining the dimensional accuracy needed for proper alignment with the cylinder block components and intake sealing surfaces. The manifold measures 16 inches long and 10.25 inches wide, with a maximum height of 5 inches at the front, center, and rear.

This part is a strong match for drivers searching for a 1993-1995 Buick LeSabre upper intake manifold, a 1993-1995 Buick Regal upper intake manifold, or a 1993-1995 Chevrolet Lumina APV upper intake manifold. It also serves 1993-1995 Oldsmobile Silhouette and Pontiac Trans Sport upper intake manifold applications, along with 1993-1994 Buick Park Avenue, Oldsmobile 88, Oldsmobile 98, and Pontiac Bonneville models. Autotecnica GM1414325 is built to restore proper intake routing and sealing on these vehicles.

What It Helps Address

• Cracked or heat-damaged upper intake manifold housing
• Vacuum leaks caused by worn manifold sealing surfaces
• Airflow irregularities from a warped or deteriorated intake manifold
• Oil vapor exposure that has degraded the original nylon manifold
• Fitment issues from a replacement part that does not match OE dimensions

Installation Notes

Verify engine and vehicle fitment before installation, especially on 1993-1995 Buick LeSabre, Buick Regal, Chevrolet Lumina APV, Oldsmobile Silhouette, and Pontiac Trans Sport applications. This upper intake manifold includes a gasket or seal, and the OE-style mounting layout with 9 holes helps support alignment during installation. Confirm the mounting hole diameter and overall dimensions against the original part before assembly.

Quality Assurance

Autotecnica GM1414325 is manufactured to OE manifold dimensions for direct replacement use and is backed by a 24 Month Unlimited Mileage Warranty.
