The K series engines are all equipped with DOHC valvetrains with Honda’s i-VTEC variable valve timing control.

Honda made this engine a big improvement over its older 4-cylinder engines by including friction-reducing technologies to reduce parasitic loss.

The K-series uses a DOHC valvetrain, which utilizes roller rockers to reduce friction. The VTEC system on engines like the K20A3 is only on the intake cam, and at low RPM when not engaged, allows the engine to function as a 12-valve engine, opening only one intake valve so that the air swirls for better combustion. This VTEC system was designed with fuel economy in mind. In engines like the K20A2 found in the RSX Type-S, The VTEC system always allows the motor to run as a 16 valve engine, and when VTEC engages, its on both the intake and exhaust rockers, and opens all 4 valves even more at high RPM

The K-series motors all use DI, or distributor-less ignition. It uses a coil on plug system, in which each spark plug has its own coil atop it. This allows the ECU to send the spark exactly when it wants it, and removes the need for spark plug wires.

After accidentally locking himself in a scrapped '85 Renault for several hours at the age of 5 years old, Hans developed a love/hate relationship with cars which eventually became an obsession. Right out of high school Hans started his first business importing and selling Japanese engines. After selling the business in 2008, he launched Import Insider to obsessively cover the auto industry and offer advice and tips to import car enthusiasts.
