MAHLE Engine Intake Manifold End Seal P/N:B33549

Stop metered air from escaping at the end of the intake manifold with the MAHLE Engine Intake Manifold End Seal (P/N B33549) — a sealing ring that closes the manifold's end bore and keeps the air charge where it belongs. It fits the 2013-2019 Volkswagen Jetta and the 2016-2018 Audi A3 Sportback e-tron as a direct-fit replacement for the original seal.

• Function: Seals the end of the intake manifold bore, preventing metered air from leaking out and maintaining the correct air charge delivered to the engine.
• Application-specific fit: Engineered to the exact dimensions of the intake manifold bore on the listed Volkswagen and Audi applications — no trimming or modification required.
• Direct-fit replacement: Designed to drop into the same position as the original seal, making installation straightforward on the 2013-2019 Jetta and 2016-2018 A3 Sportback e-tron.
• MAHLE quality: MAHLE is a global OE supplier to major automakers; this seal is built to the same standards as the original equipment part it replaces.
• Cross-reference: Interchanges with VAG part number 04E 129 717 C, so it can be confirmed against existing part documentation before purchase.

A worn or cracked intake manifold end seal allows metered air to escape the manifold before it reaches the combustion chamber. Signs that this seal may need replacing include a rough or unstable idle, a lean-running condition, reduced throttle response, or an illuminated check engine light with a lean mixture or MAF-related code. Because these symptoms overlap with other vacuum leaks and fuel-delivery issues, a proper diagnosis is recommended before replacing any single component. If the end seal is confirmed as the source of the air leak, replacing it addresses that specific leak point.
