Overview

This RAD-Spec ECU is specifically for the 03-05 Accord with an I4 engine and manual transmission. It comes with In-ECU R1 Headers pre-installed.
Show original supplier description
This particular unit, designated as RAD-Spec, is engineered for the 2003-2005 Accord models equipped with an I4 engine and a manual transmission. This prepped ECU features In-ECU R1 Headers already installed, simplifying the setup process for advanced tuning. However, it is important to note that the KTUNER BOARD itself is not included with this ECU and must be acquired separately. The unit is intended for use with K-Series Honda vehicles. This product is identified as an aftermarket replacement ECU with pre-installed KTuner headers, ready for the installation of a KTuner Rev 1 InECU unit. Please be aware that this product is intended for off-road research and development testing only, and vehicles should be flashed back to factory settings before driving on public roads.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
