Description
Product Overview
The iFJF EGR Delete Kit for 6.6L Duramax LML diesel engines provides a complete, bolt-on solution to eliminate the problematic exhaust gas recirculation (EGR) system from your 2011–2016 Chevrolet Silverado or GMC Sierra 2500HD/3500HD. Crafted from stainless steel and billet aluminum, this kit replaces the failure-prone factory EGR valve, cooler, and all associated plumbing with high-quality block-off plates and a bypass hose.

Performance Benefits
-
Eliminates Soot Buildup — No more clogged EGR valves restricting flow
-
Lower Coolant Temperatures — Faster recirculation without the EGR cooler in the loop
-
Quicker Turbo Spool — Reduced exhaust restriction = faster boost response
-
Lower EGTs — Exhaust gas temps run cooler without EGR recirculation
-
No More EGR Cooler Failures — Most common LML failure point eliminated entirely
Installation
Professional installation is highly recommended. A tuner with EGR-delete capability is required to prevent check engine lights and diagnostic trouble codes. This kit is a direct bolt-on replacement — no modification to factory components is needed beyond removing the EGR system.
Frequently Asked Questions
Q: Will my truck throw a check engine light after installing this?
A: Yes, unless you use an EGR-delete-capable tuner to suppress the related diagnostic trouble codes.
Q: Can I install this without removing the intake manifold?
A: The intake manifold stays in place. This kit is designed to work while retaining your factory intake and exhaust manifolds.
Q: Is this compatible with a DPF delete?
A: Yes, this kit works perfectly alongside a DPF/CAT delete pipe. In fact, many customers install both as a complete emissions delete package.
Q: How long does installation take?
A: Approximately 2–3 hours for a professional mechanic. DIY installers should budget 3–5 hours depending on experience.
