Korwin KWNC0079 from Ozon (Oct 2026). Che Guevara posted an Ozon listing for a FAW X80 ignition coil, reports that it is heavy, well made and works 12. The photo shows a black plastic coil with a mounting flange, engraved KORWIN, KWNC0079, 3603040A37K and the date code 20251111/06 A 3. 3603040A37K is also the number on the AliExpress coil set discussed in the same thread.

YAOSONG four-coil set from AliExpress vs the Bosch original (Oct 2026). Prosto Zuev found a set of four "high-performance" coils (red, 105 mJ, 2-year warranty) listed for FAW Bestune B50, B70, B90 and X80 1.8L/2.0L/2.3L with numbers F01R00A042 and 3603040A37K 4. Prices quoted: 4,869 RUB for the set (link text, RU market, Oct 2026) 4; 4,919 RUB per piece in the listing screenshot (RU market, Oct 2026) 5; and 4,980 RUB in the seller chat's product card (RU market, Oct 2026) 6. Prosto Zuev says that AliExpress markets it as a cooler, sportier part, while the original is Bosch, "the exact default original" 7. The seller claimed, when asked, an improved power output from added copper wire and a 5% increase 8, plus a "significant speed increase" 9; these claims are unverified. Prosto Zuev looked at reviews of the same brand on other models: some write that it is really better, others that it is the same as the original 10.
