The quest for efficiency begins with ensuring your engine breathes and fuels as effectively as possible. The factory air intake box is restrictive, often pulling in warm air from the engine bay. Installing a cold air intake (CAI) system is the foundational bolt-on. By relocating the air filter to a position that draws in cooler, denser air from outside the engine compartment and using a high-flow filter element, the CAI provides a richer oxygen mix for combustion. This allows the engine to operate more efficiently, often yielding immediate improvements in throttle response and, when paired with sensible driving, potential gains in fuel economy. On the fuel delivery side, consider upgrading the fuel injectors if they are original. Over decades, injectors can become clogged or spray unevenly.
