Does the ORIGIN Labo. S14 aero kit fit both zenki and kouki?

No, not as one kit. The S14 was facelifted in 1996 and the two front ends do not share a bumper, so ORIGIN Labo. lists every line twice: once for the zenki (1993 to 1996) and once for the kouki (1996 to 1998). As of 29 September 2026 that is Drift Line, Racing Line, Stream Line and Stylish Line for each, all at ¥102,100 ex Japanese tax (about $638) for the 3-piece kit.

What does carry across is the back half. On its Drift Line page for the S14 zenki the maker marks the side steps (part code D-308-SS) and the rear bumper (D-308-02) as shared between zenki and kouki, with only the front bumper differing: D-313-01 for the zenki, D-308-01 for the kouki. In practice that means an owner who converts a zenki to a kouki face keeps the steps and rear bumper and changes the front bumper only, ¥41,600 ex-tax. The same logic applies to Combat Eye headlight covers, which are listed per front end.

The rule to remember is that the kit follows the face the car wears, not the year on the registration, and FRP parts cannot be returned once ordered. The zenki and kouki pages with every part, the maker’s photos and the current stock notes are on the S14 catalogue page; if you are unsure which front your car wears, compare it with the maker’s photos on those pages before you order. The wider S14 market, what the cars cost and which parts are thin on the ground, is in our S14 buyer’s guide.
