Sinister Diesel Cold Air Intake for 1999-2003 Ford F-250/F-350 Super Duty (7.3L) - SD-CAI-7.3
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1999-2003 Ford F-250 and F-350 Super Duty models (7.3L Powerstroke).
Improve the efficiency and airflow of your 7.3L Powerstroke with the Sinister Diesel Cold Air Intake. Designed and engineered in-house, this system replaces restrictive factory components with a high-flow, CNC mandrel-bent aluminum intake tube. The result is significantly improved throttle response and faster turbo spool-up, providing a performance advantage whether you are towing heavy loads or daily driving.
The kit features an oversized, reusable cotton media filter that eliminates the need for disposable paper filters while maintaining high filtration standards. Every tube is finished in a durable, signature Sinister Blue powder coat to resist corrosion and enhance the engine bay's appearance. Installation is a straightforward drop-in process using basic hand tools, with high-temperature silicone couplers included to ensure a secure, heat-resistant seal.
- CNC mandrel-bent aluminum intake tubing for smooth, unrestricted airflow
- Oversized reusable cotton media filter for long-lasting service life
- Signature Sinister Blue powder-coated finish
- High-temperature silicone couplers for maximum durability
- Direct drop-in installation with included mounting hardware
- Manufacturer Part Number: SD-CAI-7.3
