How does the HP-7031 keep oil flowing under long service intervals?

The filter’s large-capacity pleated synthetic-blend media and optimized internal flow path maintain consistent oil delivery even as the element loads with contaminants. Laboratory burst-strength testing confirms the canister and media resist pressure spikes during extended intervals.

• High-flow design reduces restriction while preserving filtration efficiency
• Reinforced canister resists deformation at elevated pressures
• Tested for capacity and burst strength to suit extended change intervals

Will this filter work with my vehicle and oil type?

The HP-7031 is engineered to fit a range of Volkswagen Group models (VW, Audi, Seat) spanning early 2000s through mid-2010s, and is compatible with synthetic, conventional, and blended oils. Confirm fitment against your vehicle’s year, make and model before purchase.

• Laboratory-tested to verify capacity and burst strength

Who is this filter for? The K&N HP-7031 suits drivers who own compatible Volkswagen Group vehicles and want a durable, high-flow oil filter that supports extended oil change intervals and easier servicing. It’s a good choice for independent shops, DIY enthusiasts, and owners using synthetic or conventional oils who prefer a robust replacement part backed by testing and a limited warranty.
