BMW Exhaust Manifold Gasket SG Store Direct OEM Replacement 2 Pack

Description

Product Overview

The SG Store exhaust manifold gasket set is engineered as a direct replacement for the original equipment manufacturer (OEM) part number 18107549447. Designed specifically for BMW 1 Series models (E81 produced from 2006 to 2011 and E87 from 2005 to 2011) as well as the 3 Series E90 (2004‑2011), this set guarantees a seamless fit without the need for any modifications. The two‑piece package provides everything required for a complete gasket replacement, ensuring that both sides of the intake and exhaust manifolds are sealed simultaneously for optimal performance.

Each gasket is fabricated from a high‑temperature resistant composite material that combines the flexibility needed to conform to the complex contours of the manifold with the durability required to withstand the harsh environment of the engine bay. The material composition resists cracking, deformation, and chemical attack from exhaust gases, delivering a service life that exceeds typical aftermarket alternatives. The gaskets measure 4.84 x 3.03 x 0.28 inches and weigh only 1.06 ounces each, making them lightweight yet robust enough to handle the thermal cycling of modern BMW engines.

By preventing high‑temperature exhaust gas leakage, the gasket set maintains the intended flow path from the exhaust manifold to the three‑way catalytic converter and downstream exhaust pipe. This uninterrupted flow eliminates the risk of power loss, reduces the chance of unburned fuel entering the exhaust system, and protects the catalytic converter from premature degradation. In addition, the sealed design helps preserve engine vacuum, which is essential for accurate sensor readings and stable idle control.

Installation is straightforward and can be completed by a competent DIY enthusiast or a professional mechanic in under an hour. The gaskets are supplied pre‑shaped to match the OEM contours, so no trimming or adjustment is necessary. Simply remove the old gasket, clean the mating surfaces, and press the new gasket into place. The design includes built‑in alignment tabs that guide the gasket into the correct position, reducing the likelihood of installation errors and ensuring a leak‑free seal on the first attempt.

The packaging includes two gaskets, each individually wrapped to protect against contamination during shipping and handling. The compact dimensions of the package (4.84 x 3.03 x 0.28 inches) make it easy to store in a workshop or garage. The product is backed by SG Store’s quality assurance program, which includes a limited warranty against manufacturing defects, giving customers confidence in the long‑term reliability of the purchase.

Usage

This gasket set is ideal for owners of compatible BMW models who are experiencing symptoms such as rough idle, reduced engine power, unusual exhaust noises, or a check‑engine light triggered by exhaust leak detection. It is also an excellent preventative maintenance item for vehicles that have high mileage or have been subjected to demanding driving conditions, such as track days or heavy towing. By replacing the gasket before a failure occurs, drivers can avoid costly downstream damage to the catalytic converter, oxygen sensors, and even the engine itself.

In addition to routine replacement, the gasket set is suitable for performance upgrades that involve aftermarket intake or exhaust manifolds. Because the gasket is designed to match the OEM sealing surface, it provides a reliable interface between the stock engine block and any upgraded components, ensuring that performance gains are not compromised by leaks. The product’s compatibility with both the 1 Series and 3 Series platforms makes it a versatile choice for enthusiasts who own multiple BMWs or who service a range of models in a professional shop.

The gasket set can be installed in a variety of environments, from a home garage with basic hand tools to a fully equipped service bay with torque wrenches and diagnostic equipment. The low weight and compact size of the gaskets mean they can be handled easily, and the clear labeling on each piece helps prevent mix‑ups during multi‑vehicle service. Whether the vehicle is being repaired after a coolant leak, after a failed intake manifold, or as part of a scheduled maintenance interval, the SG Store gasket set delivers consistent sealing performance.
