Companion to spark plugs — options, prices, reliability and OEM spark plug specifications: how to read Torch plug codes, which listings were shared, and the conflicting gap rules.

Reading Torch codes. A Torch chart decodes the electrode letters: A is a 5 mm ignition position, T is 3 mm, I is an iridium centre electrode, II is double iridium, IU is iridium centre with a U-grooved ground electrode, IP is iridium and platinum, P is a platinum centre, PP is double platinum, J is three ground electrodes, Q is four ground electrodes, IQ is an iridium centre with four ground electrodes and Y is a surface-discharge type. The poster highlighted IP and the I-to-IU group¹². Searching by code can fail: the Latin Q is easily typed as G or as the Cyrillic K, which returns KH- or GH-coded listings (a search for GH5RIU13 found nothing, and an Ozon search for QH5RIU11 showed KH5RIU11 items). Members say QH5TIP and QH5RIU11 are not real Torch codes; the direct replacements they cite are QH6RIU-11 and QH5RIU-13³⁴⁵⁶.

Factory plug. A photo of a FAW-branded plug box (part number 3707010-37K, dated 2018-09-06, Changchun) shows a plug marked QH6RTIP. The Torch catalog lists QH6RTIP as the FAW fit: M14x1.25 thread, 25 mm reach, 16 mm hex, 1.1 mm gap, iridium with a platinum electrode; cross-references NGK ILTR6A13G, NGK PLTR6A10G, Denso ITV20 and several Mazda codes⁷²⁸⁹. The QH6RTIP-13 four-pack was cross-listed on Yandex Market (January 2025) against Ford 1M5O-12405-CA, AYFS-092FE-C and Motorcraft AYFS22FE1J¹⁰.

Gap: three positions. The manual's ignition-system table (screenshot) gives CA4GD1: QH6RTIP, gap 0.7-0.8 mm; CA4GC18T: ILTR6J8, gap 0.8 mm, and says not to adjust the gap of iridium plugs. A member quotes a different rule, that iridium plugs may be set anywhere in 0.6-1.1 mm. Owners report in practice: NGK plugs run about 80,000 km at the factory 1.2 mm gap without adjusting, and another owner advises Denso or Torch plugs at 1.3 mm because the engine adapts. The asker, on the atmospheric CA4GD1, ran an NGK ILTR5A-13G (heat range 5) while the manual specifies heat range 6, and asked whether 0.7-0.8 mm is needed^1112131415.

Alternatives and listings. - TORCH QH6RIU-11 on AliExpress, sold in lots of 2 to 8: ~1,867 RUB (RU market, November 2024, after a 40% discount); named replacement for NGK LTR6IX-11 (also written LTR6IX11, SILTR6A7G, ILTR6B11, ILTR6E11, ILTR6J11) and GM 12622561 and 12565996¹⁶. - TORCH QH6RTIP-13, 4 pcs: 2,003 RUB (RU market, January 2025), page marked out of stock; a member relayed an unconfirmed Telegram rumour that plug prices may rise or counterfeits may appear¹⁷. A member put a set of iridium plugs at about 2,000 RUB (RU market, April 2025), other variants higher⁷. - TORCH QH5RIU-13 (4 pcs, M14x1.25, analogue of NGK ILTR5A-13G) on Ozon, October 2025. One owner fitted a 4-pack without adjusting the gap and it runs fine; the Torch plugs were his fallback when the QH6RTIP was out of stock. Another owner replaced QH6 platinum plugs with QH5, and one had run NGK for 80,000 km before^1819202122. QH5RIU13 was also posted at a Crimea parts shop without price or fitment note²³. - A Wildberries listing titled as a Torch plug for the X80 (product 140394281) was shared in February 2025 without price or code; check its cross-reference codes before buying²⁴. - Miles ALSP067: recommended by one member after 5,000 km without complaints and at a low price; a commenter warns that heat range (калильное число) and other specs matter, since cheap plugs can cost fuel economy or damage pistons and valves, and the member replies that he chose by specs and that the seller's own listed plug has the wrong heat range²⁵²⁶²⁷. - Price context: a plug cost about 800 RUB at a parts shop (RU market, September 2024) and dealers charge 100-200 RUB more; one order took two weeks²⁸.
