Please tell me the specific Kia model and year you're asking about.
The "Kia 1.5" designation doesn't tell me enough. Kia has many models with 1.5-liter engines, and some are interference engines, while others are not.
For example:
* Kia Forte (2020-Present): The 1.6L engine is an interference engine.
* Kia Seltos (2021-Present): The 1.6L engine is an interference engine.
* Kia Rio (2018-Present): The 1.4L engine is a non-interference engine.
Once you provide the specific model and year, I can check the technical specifications and give you a definitive answer.
