FAQ
Do these nozzles require tuning?Yes. To realize the ~100 HP potential and maintain drivability and safe EGTs, custom tuning is strongly recommended.
Will these fit my 2007 truck?
They fit 2007.5 (mid-year) and newer through 2012 6.7L Cummins. If your truck is a 2007 with the 5.9L, these will not fit.
Do I need a lift pump?
A quality lift pump is highly recommended to maintain steady supply pressure under load, especially with added fueling.
Are these emissions compliant for on-road use?
These are intended for competition/off-road use where permitted. Check and follow all local, state, and federal regulations.
Is there a core charge?
No core charge applies to nozzles. Core policies may apply to complete injector sets or pumps sold separately.
