Even High Revving Hondas Gain Efficiency with a K&N Air Filter
- 1 Aug 2016
This pair of Honda engines is reminiscent of the television infomercials where the announcers read “but wait, there’s more.” Both the Honda D and K engines had long service lives in a surprising variety of vehicles, with any number of versions to suit the applications. Clearly, not only were they well designed but ongoing R&D kept their performance at the level of newer engines. What’s surprising (or maybe not) is that all these applications utilize the same K&N replacement air filter 33-2104. The Honda D series inline four cylinder engine was installed in a number of different of models, most commonly the Honda Civic, CRX, and the first-gen Acura Integra between 1984 and 2005. Engine displacement ranges between 1.2 and 1.7 liters. The D Series engine was constructed as either SOHC or DOHC, and was at times fitted with Honda’s VTEC variable valve timing system.
The Honda K series engine is also an inline four cylinder engine introduced in 2001. The K series engines were equipped with dual overhead camshafts and utilized roller rockers to reduce friction. The engines use coil-on-plug ignition for each spark plug. This eliminates the need for a conventional distributor in favor of allowing the ECU to control ignition timing based on engine sensor inputs. Two versions of the Honda i-VTEC system have been used on the K series engine, one optimized for fuel economy, the other performance. And once you’ve installed your K&N 33-2104 air filter you’ve eliminated the need to purchase and replace paper filters for the life of your Honda. The only maintenance needed is a service you can do yourself in just a short time. At up to 50,000 miles or 80,000 kilometers (depending on your driving conditions) clean and re-oil your air filter with a K&N air filter cleaning kit, returning it to like-new condition.
