70 mm High-Flow Sport Air Filter for Ford Focus RS Escape

70 mm high-flow sport air filter: an engine that can truly breathe

This 70 mm conical high-flow sport air filter replaces the original paper cartridge in Ford Focus RS, Ford Escape, and Lincoln MKC vehicles. A high-flow air filter is not just a styling accessory: its pleated oiled cotton media allows significantly more air through than a paper filter with the same pressure drop, while still trapping particles. The engine draws air more freely, throttle response becomes crisper, and the intake noise becomes more noticeable when accelerating.

Why choose this cold air intake filter

• 70 mm inlet: the most common size for cold air intake kits and modified airboxes.
• Multi-layer oiled cotton: the airflow is superior to that of a new paper filter, and it does not collapse as the filter becomes clogged.
• Washable and reusable: cleaning every 15,000 to 20,000 km is enough, with no need to buy replacement consumables.
• Rubber base with integrated clamp: direct mounting on a 70 mm intake pipe.
• Internal metal mesh: the media does not collapse under vacuum at full load.
• Reference OFI106, with dimensions equivalent to the E-2993 format, for comparing without making mistakes.

For which applications

The conical format of this car air filter is suitable for the Ford Focus RS and Ford Escape, as well as the Lincoln MKC, which shares the same technical base. It can be fitted either as a direct replacement in a prepared airbox or at the end of a direct intake kit on a 70 mm pipe. On a turbo engine, the benefits are twofold: the compressor benefits from unrestricted cold air, and the turbo sound becomes clearer. Always measure the outside diameter of your pipe before ordering: check before installation.

Technical specifications

Reference: OFI106. Format: universal conical. Inlet diameter: 70 mm. Height: approximately 152 mm. Outside diameter: approximately 127 mm at the base. Media: multi-layer pleated oiled cotton, red-tinted. Frame: black epoxy-coated steel mesh. Base: rubber with integrated clamp. Maintenance: washable and re-oilable. Operating temperature: up to 100 °C continuously.

Installation and maintenance

Allow 15 minutes, with a cold engine. Remove the original cartridge or previous filter, check the condition of the pipe, push the filter fully onto the 70 mm inlet, then tighten the clamp by hand until firmly secured. Check that no moving parts or hot hoses touch the media. Maintenance: disassemble, brush dry, spray with a cotton filter cleaner, rinse with lukewarm water from the inside out, leave to air dry, then re-oil lightly. Never dry with compressed air, as this deforms the pleats.

Frequently asked questions

Does a sport air filter increase power?
On a stock engine, the gains remain small. They become significant when the intake is already the limiting factor: tuned engine, modified exhaust system, engine remapping.

How many kilometers between cleanings?
Allow 15,000 to 20,000 km for road use, and much less in dusty environments or on the track.

Should it be re-oiled after every wash?
Yes. The oil is what traps fine particles; a dry cotton filter does not filter well. Use a light coating to avoid clogging the mass airflow sensor.

What is the exact inlet size?
70 mm inner diameter, on a rubber base. Measure the outside diameter of your pipe before ordering.

Is this filter noisy?
When exposed to the air, the intake becomes audible when accelerating. In a closed airbox, the noise level remains close to stock.

A washable filter bought once and for all: no more cartridges to replace at every service, and an engine with crisper throttle response.
