Our take on the Denso Auto Parts DENSO 280-5104 Remanufactured Starter Motor

The Denso 280-5104 is a remanufactured 12V permanent-magnet gear-reduction (PMGR) starter rated at 1.7 kW, built by an OEM supplier that also makes new starters. It is a bolt-on replacement that turns clockwise and ships with shims but no mounting hardware. Denso reman units are rebuilt to factory spec and are a common choice over cheap new no-name starters. It is listed for racing use, so check that it fits your engine and rules before ordering.

Questions and answers

Is this starter worth it over a cheap new one?
Yes, if the part number matches your engine. Denso is an OEM supplier and reman units are rebuilt to factory spec, which usually outlasts low-cost new starters. You pay more than a no-name unit but less than new OEM.
Will it fit my car?
Fit depends on the 280-5104 part number matching your engine, not on the brand. Confirm the interchange number for your vehicle before ordering. It is listed for racing use, so verify class rules too.
What is in the box?
The starter and shims. Mounting bolts and hardware are not included, so reuse your original bolts or buy new ones.
Is a remanufactured starter as good as new?
A Denso reman uses a rebuilt original housing with new wear parts and is tested to spec. Quality is close to new when the core is good, but a bad core can slip through, so test it before installation.
When is it cheapest?
Reman starters rarely go on deep discount. Compare prices across stores and factor in any core charge, which can change the real cost.
