Engine Air Filter vs Cabin Air Filter

Understanding the difference between the engine air filter and the cabin air filter for your 2018 Hyundai Ioniq Plug-In Hybrid keeps both performance and comfort at their best. The engine air filter is a first line of defense for the hybrid powertrain: it prevents dirt and particulates from entering the engine’s intake, preserving horsepower, hybrid system efficiency, and fuel economy.

Maintaining both filters saves you money immediately—by preventing reduced fuel efficiency and clogged systems—and over time by avoiding premature component wear.

Scheduling is easy online: schedule service to have both filters inspected and replaced if necessary, or review our value-driven service specials to reduce the cost further.
