Yes. This motor is a guaranteed 100% direct fit for the 2012, 2013, 2014, and 2015 Honda Civic Si. It bolts right into the factory mounts without any hassle.

What mileage range is typical for imported Honda Civic Si engines?

Our imported engines typically have around 45,000 to 65,000 mileage range. This ensures you get a fresh, low-mileage motor.

Is this K24A R40 engine a direct replacement without modifications?

Absolutely. It is a true OEM engine replacement, meaning no custom fabrication or tricky modifications are needed.

Are Honda Civic Si engines tested before shipping?

For sure. We run strict visual inspections on every motor to verify it is healthy and ready to install.

Do imported Honda Civic Si engines come with warranty coverage?

Yes. We stand behind our motors with a comprehensive warranty policy so you can buy with total confidence. Read full details here.

Can this Honda Civic Si engine be shipped nationwide?

Yes, we freight ship directly to commercial addresses or freight terminals across the entire United States.

Why choose a JDM Honda Civic Si engine over a local used engine?

JDM engines are famously better maintained and have way lower mileage. A used Honda Civic Si 2.4L engine from Japan is just cleaner inside and out. A local motor is usually pulled from a high-mileage and is way more risky. 

What maintenance is recommended before installing a used Honda engine?

We highly recommend swapping over your USDM sensors, water pump, and thermostat. Doing a fresh spark plug and fluid service before dropping is also important.
