HIGHFLOW High Performance

Premium Guard HIGHFLOW PA99540X is a pre-oiled, disposable high-performance engine air filter engineered to increase airflow and trap more dirt than standard paper filters while fitting select 2021–2025 Hyundai and Kia models.

This HIGHFLOW replacement filter is built for drivers who want a no-fuss upgrade that improves engine breathing under load and offers stronger particle protection than basic paper elements. Pre-oiled and ready to install, the PA99540X is dimensioned to match OE fitment for models such as the 2022–2025 Hyundai Tucson, 2021–2025 Santa Fe, 2023–2025 Kia Sportage, and several others. The design balances increased air volume with durable filtration media so you get performance gains without sacrificing protection.

How does this filter boost engine airflow and performance?

The HIGHFLOW media is engineered to allow up to 50% more air volume than standard paper filters when the engine is under load or accelerating. More air supply helps the engine work more efficiently during heavy throttle, without exposing it to extra contaminants thanks to the pre-oiled barrier.

• Pre-oiled synthetic media for unrestricted airflow under acceleration
• Engineered pleat geometry to increase usable filter surface area
• Maintains stable flow rates across typical driving conditions

Will it protect my engine as well as the original filter?

Yes — the HIGHFLOW PA99540X uses a premium pre-oiled media with roughly double the dirt-blocking capacity of basic paper filters, providing robust particle capture before air reaches the engine. The filter is tested to meet or exceed Hyundai OE filtration requirements for the listed applications.

• Superior dirt-holding capacity compared with basic paper elements
• High-efficiency media that reduces inlet contamination risk
• Replaceable as a disposable unit—no washing or re-oiling required

How easy is installation and vehicle fitment?

Installation is straightforward: the HIGHFLOW filter ships pre-oiled and ready to drop into the factory airbox, with form and sealing surfaces matched to OE dimensions. Always confirm part compatibility with your vehicle using the vehicle filter guide or the OEM replacement number.

• Direct replacement for Hyundai 28113L1000 where applicable
• Designed to fit specified Tucson, Santa Fe, Sonata, Tucson, Carnival, Sorento, Sportage, K5 model years
• No additional tools, treatments, or re-oiling needed before installation

What maintenance and replacement schedule should I follow?

Because this is a disposable pre-oiled filter, replace it according to your vehicle manufacturer’s recommended service interval or sooner in dusty conditions. Regular inspection during routine service helps maintain peak airflow and filtration performance.

• Replace per OEM interval or earlier if driving in heavy-dust environments
• Inspect for tears, heavy contamination, or damaged seals at service
• Dispose and install a fresh HIGHFLOW unit—no cleaning or re-oiling

Who is this for: Drivers who want a simple, high-performance air filter upgrade that increases airflow during acceleration while offering stronger particle protection than standard paper filters. It’s ideal for owners of compatible 2021–2025 Hyundai and Kia vehicles who prefer a ready-to-install disposable option with OE-style fitment and enhanced filtration capacity.
