FAQs

Does this system require tuning?
High-flow PLUS systems at this level are intended for built applications (900–1200 HP). Many vendors and builders recommend appropriate tuning. Always verify for your setup.

Which filters does this system use?
Use the current two-filter combo: XWS3002 (water separator, pressure side) + PF3001 (particulate, suction side). Do not mix with older FF/FS series elements. See items linked above.

Will it help injector life and starting?
Yes—air/vapor removal plus 2-micron filtration helps protect injectors; polishing and optional heaters improve cold-weather operation.

Is fabrication required to mount it?
Standard pickup installs use a bolt-on bracket at the factory bed bolt. Cab-and-chassis may require modifications.
