Honda K20A Engine 2.0L
The Honda K20A is a 2.0-liter inline-4 engine produced by Honda from 2001 to around 2010. It is widely regarded as one of the greatest four-cylinder engines ever built, representing the pinnacle of Honda's high-performance naturally aspirated engineering and the final evolution of the "red top" VTEC legacy.
