What is the original brand of the spark plugs for the Malibu XL?

The spark plug model for the Chevrolet Malibu is LTR6IX-11. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high voltage electricity into the combustion chamber and generates a spark by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. The structure of the spark plug is described as follows: 1. Steel shell: The lower part of the steel shell has fine threads for installation into the cylinder head's spark plug hole, while the upper part features a hexagonal nut for use with a spark plug socket to tighten or remove the spark plug. 2. The metal rod serves as the center electrode. The lower end of the metal rod contacts the upper end of the center electrode through a conductive glass body, and the upper end of the metal rod is equipped with a terminal nut. 3. Between the steel shell and the center electrode, there is a high-alumina ceramic insulator that insulates the center electrode when electrified. 4. The lowest part of the steel shell is fitted with a curved side electrode. 5. The middle of the steel shell's exterior has a copper gasket.
I've been driving my Malibu XL for several years, and the original spark plugs are usually ACDelco brand. You can refer to the manual for the specific model number. Spark plugs are the core component of the ignition system, responsible for igniting the air-fuel mixture in the cylinders. As GM's own parts brand, ACDelco is specifically designed for the Malibu XL engine, offering high compatibility to optimize combustion efficiency and reduce fuel consumption. These are installed when the car is new, and the replacement interval is generally around 80,000-100,000 kilometers. If you notice sluggish acceleration or a sudden increase in fuel consumption, it's time to check the spark plugs. Personally, I recommend not switching to other brands randomly. While NGK or Bosch can also be used, the original ACDelco plugs are more stable and reduce the risk of ignition failure. Cars that maintain original parts tend to have more reliable overall performance. When replacing them, have a professional technician assist to ensure proper sealing and gap settings, preventing future issues.
As a Malibu XL owner, the original spark plug brand is ACDelco, a brand under General Motors that has been used for many years. Spark plugs play a crucial role in starting and driving, and matching the original ones ensures precise ignition. I replace them every 70,000 to 90,000 kilometers myself. ACDelco spark plugs have good longevity, quick ignition, and low noise. If you switch to off-brand ones, it may affect engine smoothness or even cause vibrations. During maintenance, check the spark plug tips for carbon buildup or burns, and clean them if necessary to save costs. I also found that original parts can be purchased at 4S stores, which is convenient and affordable. New car owners don’t need to worry—just understanding these details will make driving more reassuring.
