PRODUCT DETAILS
Denso Starter Motor (280-0334) - 2002-2005 Honda Civic Si (EP3)
When your EP3 cranks slow or clicks and won't turn over, the starter is usually done. This is a Denso remanufactured starter, and the important part is that Denso was the original manufacturer, they're reman-ing their own unit. That's a different thing from a generic rebuild, and Denso's process is good enough that these have some of the lowest return rates in the aftermarket.
Denso Reman Isn't A Generic Rebuild
Worth understanding, because reman quality varies enormously and this is at the top of it.
A cheap remanufactured starter is a used core with the obviously bad parts swapped and not much else checked. Denso's process is thorough: armatures and field coils are high-voltage tested to confirm they perform, commutators are refinished and performance validated, and the terminals and fasteners are replaced with quality copper for a clean electrical path.
That rigor is why these have the lowest return rates in the replacement aftermarket. A starter that's properly remanufactured to the original manufacturer's standard behaves like a good starter should, rather than being a gamble on someone else's rebuild.
No Core Charge
Worth calling out, because it's cleaner than the usual reman arrangement.
Most remanufactured parts carry a core charge, a deposit you pay up front and get back only after shipping your old unit in. Hybrid Racing covers the core on this one, so there's no core charge and nothing to send back. The price you see is the price, and you're not chasing a refund after the fact.
Denso Starters Are Genuinely Tough
Worth knowing, since it speaks to the underlying design.
Denso starters are rugged enough that they're often adapted for racing use, where reliable, high-torque cranking matters and failure isn't an option. That's the base unit you're getting reman'd here, engineered for maximum cranking torque under all conditions.
On an EP3 that starts and restarts constantly, whether it's a daily or a track car, a starter that cranks strong every time regardless of heat or cold is what you want.
Direct OE Replacement
This replaces the factory starter directly, equivalent to Honda OE part number 31200-PNE-G01.
It's a 1.1kW, 12V, clockwise-rotation unit matched to the EP3's K20A3, so it bolts in where the original came out and connects the same way. No adapting, no compatibility guesswork.
Backed For A Year
Denso covers this with a 12-month warranty, which on a remanufactured part is a real statement of confidence in the process. A cheap reman with a short warranty tells you what the manufacturer expects of it; a year from Denso tells you they expect it to last.
Know The Signs Of A Failing Starter
Worth recognizing, so you're replacing the right part.
A dying starter usually announces itself: slow, labored cranking, a single click with no crank, intermittent no-starts that get worse, or a grinding noise on engagement. If your battery tests good and the car still won't turn over properly, the starter is the likely cause.
Those symptoms can also come from a weak battery or corroded connections, so rule those out first, they're cheaper to fix. But if they check out and the starter is struggling, this is the fix.
Fitment

Who Should Grab This
This is for the EP3 owner whose starter is cranking slow, clicking, or failing to engage, and who wants a properly remanufactured unit rather than a cheap rebuild that fails again. It's Denso reman-ing their own starter to their own standard, high-torque, thoroughly tested, warrantied for a year, and with no core to send back. Confirm your battery and connections are good, swap it in, and get reliable starts back.
