This article is about the Honda engine. For the Rover engine series of the same name, see Rover K engine.
A cylinder head from a Honda K20Z3. Components of the i-VTEC system can be seen.

The Honda K series engine is a four-cylinder four-stroke engine introduced in 2001. The K series engines are equipped with DOHC valvetrains and use roller rockers to reduce friction. The engines use a coil-on-plug, distributorless ignition system with a coil for each spark plug. This system forgoes the use of a conventional distributor-based ignition timing system in favor of a computer-controlled system that allows the ECU to control ignition timings based on various sensor inputs. The cylinders have cast iron sleeves similar to the B-series & F-series engines, as opposed to the FRM cylinders found in the H-series and newer F series engines found only in the Honda S2000.

Similar to B series, K-Series has two short blocks with the same design; the only difference between them being the deck height. K20 uses the short block with a deck height of 212mm where K23 and K24 block has a deck height of 231.5mm.[1]

Two versions of the Honda i-VTEC system can be found on a K series engine, and both versions can come with variable timing control (VTC) on the intake cam. The VTEC system on engines like the K20A3 only operate on the intake cam; at low rpm only one intake valve is fully opened, the other opening just slightly to create a swirl effect in the combustion chamber for improved fuel atomization. At high rpm, both intake valves open fully to improve engine breathing. In engines such as the K20A2 found in the Acura RSX Type-S, the VTEC system operates on both the intake and exhaust valves, allowing both to benefit from multiple cam profiles.
