Why an LS Oil Cooler Block Off Plate is Beneficial

When I first started modifying my LS engine, I quickly realized the importance of managing oil temperature for optimal performance. One of the best decisions I made was to install an LS oil cooler block off plate. This simple component has made a significant difference in my engine’s efficiency and longevity.

By blocking off the oil cooler, I’ve noticed a more consistent oil temperature during my drives.

With the block off plate, I’ve been able to maintain a more stable temperature, ensuring that my oil flows properly and lubricates all the crucial components effectively.

Additionally, I found that the block off plate helped streamline my engine bay. By eliminating the oil cooler, I reduced potential points of failure and simplified my oil routing. This not only made maintenance easier but also gave my engine a cleaner look. Overall, using an LS oil cooler block off plate has been a straightforward yet impactful upgrade in my engine management strategy.
