A Kia Forte needs a spark plug matched to its model year and engine, rather than a plug selected from the vehicle name alone. Kia used different engines and plug specifications across generations. The specific fitments below come from direct retailer or manufacturer listings and are deliberately limited to the stated engines and years. The final card is a narrower-generation alternative; confirm every plug against the exact engine and VIN before purchase. Buy the complete engine set, follow the manual’s torque specification, and do not change the gap on a fine-wire precious-metal plug unless the service information explicitly says to do so.

The picks, in detail
NGK 4469 IX Iridium Spark Plug
FinditParts lists NGK 4469 for 2010–2013 Kia Forte applications. Keep that year limit attached when shopping; this is not a universal replacement for later Fortes.
- NGK stock number 4469
- Retailer lists 2010–2013 Forte
- Iridium IX construction
- Exact NGK number
- Confirm engine with the seller
NGK 93175 Iridium IX Spark Plug
NGK identifies 93175 as LKR7DIX-11S and lists it for Forte 1.8L models from 2014–2016 and Forte 2.0L models from 2016–2018.
- NGK 93175 LKR7DIX-11S
- Forte 1.8L: 2014–2016
- Forte 2.0L: 2016–2018
- Maker-published fitment

- Does not cover 2014–2015 2.0L
NGK 96355 Ruthenium HX Spark Plug
CarParts lists NGK 96355 for the 2010 Kia Forte 2.0L. It belongs only with that exact year-and-engine description unless a separate catalogue lookup proves another application.
- NGK stock number 96355
- 2010 Forte 2.0L listing
- Ruthenium HX electrode
- Modern precious-metal design
- No wider Forte claim made
Denso 5356 Iridium Power Spark Plug
Denso 5356 is listed for 2014-2018 Forte applications and gives owners of that generation another iridium option. Check the exact 1.8L or 2.0L engine and trim in a fitment catalogue before ordering; it is not a plug for every Forte.
- Denso 5356 IXUH22I
- Forte 2014–2018 listing
- Iridium Power design
- Published Forte year range
- Exact current listing price
- Confirm engine before ordering
Close alternative: Bosch 9625 Double Iridium Spark Plug
Bosch 9625 is a newer-generation choice listed for 2022-2024 Forte 2.0L models. It is a close alternative for the article as a whole, not an interchangeable plug for the older 2010-2018 engines above; match the VIN and engine first.
- Bosch part 9625
- Forte 2.0L: 2022–2024
- Double-iridium design
- Explicit newer Forte fitment
- Distinct brand option
- Not for earlier Forte generations
