LOW RESTRICTION PERFORMANCE FILTER (LRES) - Fits Ford style (FL-1A) Filter mounts (Fram PH8A, HP1) - Less resistance, increases oil pressure up to 15 psi. - Unlike typical paper filters, these feature heat cured, resin impregnated filter material structured within a high efficient pleating design for maximum filtration and minimal resistance resulting in cleaner oil and less pressure drop. - High polish mirror finished Chrome exterior. - Construction, quality control and performance engineered to meet exacting racing standards - 200psi burst capacity housing
ULTRA LOW RESTRICTION RACING FILTER (ULRES) - Filters down to 27 micron - (20 microns or less recommended for 100,000 mile daily drivers with long terms between oil changes) - Filtration technology experts determined particles below 20 microns are not large enough to produce engine wear, but the restrictive elements that reduce oil pressure, will! - Only drops oil pressure by less than 2.5 psi for maximum flow - White finish for no-frills all out competition performance - 500psi burst capacity housing
Use the LRES for street-strip performance & everyday driving. Use the ULRES for maximum performance in relatively clean conditions
