What makes the HP-7038 suitable for long service intervals?

The HP-7038 combines robust construction and high-efficiency filter media so it can withstand extended drain schedules recommended by many manufacturers. Uniform pleating and high-capacity media trap particulates while maintaining oil flow.

• Durable steel canister resists crushing and corrosion
• High-efficiency pleated media captures fine contaminants
• Designed to handle extended oil change intervals up to manufacturer recommendations

How does this filter improve oil flow and engine reliability?

Engineered for low restriction, the HP-7038 lets oil circulate freely under normal and high-demand conditions. That balance preserves oil pressure while ensuring contaminants are removed before recirculation.

• Media layout maintains high flow rates under load
• Uniform pleats reduce bypass risk and maintain filtration efficiency
• Compatible with modern synthetic oils for consistent lubrication

How does the welded hex nut and canister design help during maintenance?

K&N attaches a one-inch welded hex nut to the filter’s base so technicians and DIYers can quickly and securely remove the unit with standard tools. The heavy-gauge canister also stays intact during removal, avoiding messy failures.

• Welded hex nut simplifies removal with a socket or wrench
• Reinforced canister prevents deformation during service
• Thread and seal engineered for reliable, repeatable fits
