What is OEM-plus?

A modification style that uses factory or factory-style parts from higher trims or other models, keeping the car looking stock but with subtle improvements.

OEM-plus (sometimes written OEM+) describes modifications using only factory or factory-style parts. The "plus" comes from upgrading components from higher trims, special edition models, or related vehicles within the same manufacturer family. The result looks stock to a casual observer but has meaningful improvements over the original specification.

A common OEM-plus example: a base Civic LX upgraded with Si front bumper, Si wheels, Type R brake calipers, and Type R suspension. Every part is a factory Honda part. The car looks like a slightly higher trim Civic, not a modified one. To trained eyes, the upgrade is obvious; to most viewers, it just looks clean.

The aesthetic sits opposite the ricer style. Where ricer modifications emphasize visual flash and aftermarket parts, OEM-plus modifications emphasize subtlety and factory-correct execution. The community generally rewards OEM-plus builds for restraint and attention to detail.

Frequently asked questions

How is OEM-plus different from a stock car?
A stock car has only the parts it left the factory with. An OEM-plus car has factory parts swapped from higher trims or related models. Both look factory-correct; OEM-plus has actual upgrades that improve the car beyond stock specification.
Why is OEM-plus considered tasteful?
Because the parts are factory-engineered and factory-tested, the modifications look intentional rather than added on. The aesthetic respects the original design while improving it. The community generally rewards subtle upgrades over loud aftermarket modifications.
Can OEM-plus be expensive?
Yes. Genuine OEM parts often cost more than aftermarket equivalents. OEM-plus parts (especially from rare special editions, JDM-only models, or discontinued trims) can be very expensive. A complete OEM-plus build can cost as much as a comparable aftermarket build.
What is an example of OEM-plus on a BMW?
A base 328i with M3 wheels, M-tech aero kit, M-Sport seats, and M3 brakes would be a classic OEM-plus build. All BMW factory parts, all from a higher-trim BMW. The car looks like a high-spec 3-Series, not a modified one.
Is an engine swap OEM-plus?
Generally yes if the engine is a factory-correct unit from a related model. A K20 swap from an Acura RSX into a Civic, using factory mounts and wiring, qualifies as OEM-plus. An LS swap into a Miata generally does not, because the LS came from a different manufacturer.

What is shakotan? Japan's original lowered car style

Shakotan literally means low car, and it's the 1970s Japanese style that every lowered car since has descended from. Deep-dish wheels, a scraped ride height, mild flares, and clean lines. Here's what separates it from bosozoku, kaido racer, and VIP style.

What is a ricer? Where the word came from, and why it still stings

A ricer is a car modified to look fast without being made faster: big wing, loud muffler, stick-on vents, decals for sponsors it doesn't have. The word comes from "rice burner," a slur aimed at Japanese bikes and cars, and the acronym people cite is a cover story. Here's the history, the line between a ricer and a real build, and why the industry does the same thing.

What Is OEM Plus? The Build Style That Wins by Doing Less

OEM Plus, or OEM+, is a build philosophy: upgrade a car using factory or factory-style parts, often borrowed from higher trims or related models, so it looks like it could have left the factory that way. The whole point is restraint.

What Is a Sleeper Car and Why Do People Build Them?

A sleeper is a car with serious performance hiding under a completely unremarkable exterior. The classic formula is an economy car, family sedan, wagon, or even a minivan built to embarrass sports cars while looking like it is on its way to a dentist appointment. The whole point is that nothing warns you.
