Eliminate the guesswork and complete your next oil pan service properly with this Complete Genuine Volkswagen / Audi Lower Oil Sump Bolt Kit (Pack of 20).

On the modern VAG EA888 Generation 3 engine platform, the factory lower oil pan is made of a composite polymer/plastic. This layout requires exactly 20 specific fasteners to achieve a completely uniform, leak-free seal against the engine block. Because these factory M6 x 25mm Torx bolts (Part No. N91071701) feature an engineered flange face to distribute clamping pressure, reusing old, stretched, or corroded hardware risks uneven loading, oil weeping, or cracking the delicate plastic pan tabs. This pre-bundled kit gives you every single bolt required to do the job right the first time.

Key Features & Benefits

• Complete 20-Piece Kit: Outfits the entire perimeter of the lower plastic oil pan with a single click—no manual quantity calculating required.

• Genuine VAG OEM Factory Parts: Delivers the exact tensile strength, thread pitch, and anti-corrosive zinc coating required by factory workshop manuals.

• Integrated Washer Flange: Spreads clamping forces safely over the composite edge of the plastic oil pan to prevent stress fractures.

• Precision Torx Drive Head: Ensures clean tool engagement to resist cam-out slippage, making it easy to hit exact factory torque settings.

Factory Installation & Torque Specifications

To protect your composite oil pan from permanent warping or cracking, always adhere to the factory workshop assembly sequence:

1. Ensure the engine block mating face and pan channel are completely clean and oil-free.

2. Install all 20 bolts loosely by hand to ensure no cross-threading occurs.

3. Tighten the hardware in an outward criss-cross / star pattern starting from the center bolts.

4. Torque Spec: Tighten precisely to 8 Nm (approximately 70 in-lbs). Do not use high-torque power impact tools on plastic oil pans.
