Frequently Asked Questions
Q: Do I need tuning with 30% over injectors?
A: Yes—proper tuning is strongly recommended for best drivability, EGT control, and power.
Q: Will these fit my 2004 truck?
A: Only if it’s a 2004.5+ common-rail model. Early-2004 (2003–early 2004) uses different injectors.
Q: What CP3 works well with 30% overs?
A: A healthy stock CP3 can work, but an Exergy Sportsman/10mm CP3 is ideal as power goals increase. See our 03–07 CP3 page.
Q: Are these new or reman?
A: This E02 20205 set is brand-new. (We also carry reman 30% over sets if you prefer.)
Q: Warranty?
A: Covered by Exergy’s manufacturer warranty. Keep proof of purchase and follow proper install/filtration practices.
