2.4 Acura Firing Order

Here’s the 2.4 Acura firing order for early model B engines with cylinder #1 located on the driver’s side of the vehicle and later model “K” engines with the #1 cylinder located on the passenger side of the vehicle.

Acura B engine

The “B” series engines are 4-cylinder engines available with either dual overhead cams (DOHC) or single overhead cams (SOHC). The engine was introduced by Honda in 1988 and included Honda’s variable valve timing system known as VTEC (Variable Valve Timing & Lift Electronic Control) and later as the i-VTEC (intelligent-VTEC).

The “B” series was made in 1.5L, 1.6L, 1.7L, 1.8L, and 2.0L variations, with and without VTEC and was superceded by the “K” series engine in 2001. The K-series engine layout changed to located the #1 cylinder on the passenger side.

Acura K engine

Acura “K” series 4-cylinder engines

Acura K series engines are four-cylinder engines with DOHC valvetrains. They use roller rockers to reduce friction. The engines use a coil-on-plug design, with a coil for each spark plug. They do not have traditional distrubutors. Instead the ECU controls IGN timing.

The K engines have cast iron cylinder sleeves and use two different versions of variable valve timing (VVT) called VTEC (Variable Valve Timing & Lift Electronic Control) and i-VTEC (intelligent-VTEC). The VTEC system on some engines only provides VVT on the intake cam. In those engines, one intake valve opens fully, while the other only slightly. That creates a swirl effect to improve fuel atomization. Then, at higher RPMs, both valves open fully to improve volumetric efficiency.
