Why I Believe an LS Oil Cooler Block Off Plate is Necessary

As a car enthusiast and owner of a LS engine, I have learned the importance of maintaining and protecting my vehicle’s engine. One crucial component that I have found to be necessary for optimum performance and longevity is an oil cooler block off plate.

This prevents the oil from overheating and breaking down, which can lead to costly engine damage.

Moreover, using an oil cooler block off plate can also improve overall engine efficiency. With the coolant no longer circulating through the oil cooler, it reduces parasitic drag on the engine. This means that more power is directed towards driving the wheels rather than powering unnecessary components.

In addition to performance benefits, an LS oil cooler block off plate can also save money in maintenance costs. Coolant leaks from faulty or damaged oil coolers are not uncommon in LS engines. By blocking
