K&N Engine Air Filter KNA-2936 — Long-Life 18,000-Mile Replacement, High-Flow Filtration

The K&N KNA-2936 is a long-life replacement engine air filter engineered to deliver up to 18,000 miles of reliable filtration while fitting directly into your factory air box.

Built on K&N’s decades-old reputation for high-flow performance filtration, this KNA-2936 variant is offered as a premium 18,000-mile service option for everyday drivers. It uses application-specific synthetic or cellulose-blend media to balance airflow and particle capture, meets or exceeds many OEM specifications, and installs in minutes without special tools. The design is intended to give longer service intervals than standard disposable filters while maintaining strong engine protection.

How does this filter balance airflow and engine protection?

The KNA-2936 employs a carefully engineered filter media that permits steady airflow while trapping fine contaminants. Depending on the vehicle application, the media is either a high-quality synthetic or a cellulose blend to optimize efficiency and longevity. That approach helps preserve engine performance and throttle response without sacrificing filtration.

• Premium synthetic or cellulose-blend media matched to application
• Designed for high airflow while capturing up to 99% of damaging particles
• Maintains engine protection comparable to OEM expectations

How often should I replace the KNA-2936 and why choose 18,000 miles?

K&N specifies replacement at approximately 18,000 miles under normal highway driving conditions. This extended interval is roughly 50% longer than many standard 12,000-mile disposable filters, reducing maintenance frequency for drivers who primarily cover highway miles.

• Replacement interval: every 18,000 miles under typical highway use
• Longer service life lowers routine filter-change frequency and maintenance cost
• Recommended interval assumes normal driving; severe conditions may require earlier replacement

Will the KNA-2936 fit my vehicle and is installation difficult?

The KNA-2936 is designed to drop into the factory air box for compatible models and usually requires no tools to install. K&N lists numerous compatible vehicles across Citroën, Peugeot, DS, Opel, Vauxhall and Mini model years; always verify fitment for your exact year and engine code before purchase.

• Fits many Citroën, Peugeot, DS, Opel, Vauxhall and Mini models (see compatibility list)
• Direct-replacement form factor installs quickly into factory air box
• No permanent modifications; returns vehicle to stock service pattern

What are the tangible benefits of choosing this longer-life K&N filter?

Drivers choosing the KNA-2936 gain longer intervals between filter replacements plus K&N’s durable construction, which can reduce parts waste and service visits. The filter’s materials and build quality are selected to withstand extended use while helping maintain reliable engine intake protection.

• Up to 18,000 miles of service life per filter under normal conditions
• Rugged construction reduces the chance of premature failure
• Helps preserve engine performance with consistent airflow management

Who is this for? The K&N KNA-2936 is suited to drivers of compatible Citroën, Peugeot, DS, Opel, Vauxhall and Mini vehicles who prefer reduced maintenance intervals and durable filtration that installs easily into the original air box. It’s a practical choice for highway-focused commuters and owners seeking a balance of protection, longevity, and straightforward fitment without altering factory intake geometry. If you frequently drive in dusty or severe conditions, consider checking replacement intervals more often or choosing a media type recommended for heavy-duty use.
