The K24A is Honda's 2.4L DOHC i-VTEC four-cylinder — the workhorse of the mid-2000s Honda lineup and one of the most requested engines we import. Whether you're replacing a tired Accord or Element engine or building a K-swap, JDM Alliance imports K24A engines directly from Japan and stocks them at our Dallas warehouse for local pickup or crated freight nationwide.

The JDM K24A family covers the USDM K24A1 (2002–2006 CR-V), K24A4 (2003–2005 Accord and 2003–2006 Element) and the higher-output K24A2 used in the 2004–2008 Acura TSX. Japanese-market units come out of the Accord, Odyssey and CR-V and typically run 45,000–70,000 miles, documented from the auction sheet. Tell us which chassis you're putting it in — head, cam and oil pump differences between K24 variants matter, and we'll match the correct unit. The K24A is also the go-to bottom end for K-swap builds in Civics and Integras.
Each engine is sold as a long-block assembly: block, head, valvetrain, oil pan and timing components. Depending on your application you may need to transfer or source separately: intake manifold, exhaust manifold, wiring harness, ECU, sensors, and accessories (alternator, power steering, A/C) plus mounting hardware. The engine in the photos is the actual unit you receive, and we confirm the serial with you before it ships.
Every K24A is compression-tested, its auction grade is documented, and it is photographed as the actual unit. Replacement K24A engines carry our 90-day start-up warranty from the day the engine arrives.
K24A pricing varies with mileage and container timing — check the current listings below for live pricing, with free local pickup in Dallas and flat-zone crated freight to the lower 48. Inventory turns over with every container — if nothing is in stock today, call or text (469) 570-4113 and we'll reserve one off the next arrival.
Before first start-up: replace the valve cover, oil pan and rear main seals while the engine is out (cheap insurance on any import), inspect the timing chain tensioner and water pump, fill with fresh oil and coolant, and have a certified mechanic handle the install — it's also a warranty condition. If you're swapping between K24 variants, verify VTC gear, oil pump and cam sensor compatibility before ordering. Change the oil again after the first 500 miles.
Yes — when matched to the correct USDM variant, the long block bolts to your existing automatic or manual transmission and runs on your US ECU and harness. You reuse your US intake/exhaust manifolds and accessories.
Typically 45,000–70,000 miles. Japanese vehicle inspection costs push cars out of service early, which is why JDM engines average far lower mileage than US junkyard pulls.
