Thanks to its durable aluminum block, forged internals, and advanced fuel injection system, this engine is known to run for hundreds of thousands of miles when properly maintained. Because of its balance of performance and longevity, the 1UZ-FE VVT-i is also a popular choice for engine swaps into performance builds, classic cars, and off-road vehicles.
