FITMENT
- 2015.5-2016 Chevy GMC Colorado/Canyon 2.8L Duramax LWN Diesel Engine.
DESCRIPTION
Product Overview
- While the 2.8L Duramax LWN engine offers impressive mid-size diesel performance, its factory EGR setup introduces severe intake fouling and long-term breathing degradation. Recirculated carbon soot mixes directly with CCV oil mist, forming a dense, tar-like sludge across intake valves, restricting manifold volume, and fouling sensitive MAP sensors with persistent error codes.
- Engineered as a total intake-purification upgrade, this LWN 2.8L Duramax EGR Delete Kit completely eliminates the factory EGR valve and heat-stressed cooler assembly. Precision-machined block-off plates seal the exhaust manifold and intake ports—isolating the charge-air tract, preventing sensor fouling, and delivering a continuous supply of cool, dense, oxygen-rich air to your cylinders.
Key Features
-
Relies on high-grade CNC billet aluminum and laser-cut plates for a seal that stays put.
- Cuts carbon sludge at the root by stopping abrasive exhaust soot before it enters the intake, keeping sensors clean.
- Removes the fragile factory cooler to prevent the coolant-to-exhaust leaks that cause white smoke, low coolant, and hydrolock.
- Restores sharp low-end response and helps the turbo spool faster by feeding the engine clean oxygen instead of inert gas.
FAQ
Q: What do I actually gain by deleting the EGR on the 2.8L LWN?
A: You stop carbon buildup and eliminate the cooler’s leak risk. The LWN is prone to soot clogging the intake and MAP sensor, and this kit blocks that soot entirely, bringing the throttle back to life.
Q: There are two kits that cover “2016” — how do I pick?
A: GM changed the EGR connection mid-2016. Check the factory EGR tube near the firewall: a V-band clamp means this 2015.5–16 kit; a two-bolt flange means you want the 2016–2019 Kit.
Q: Does this change how often I need to change the oil?
A: The oil stays cleaner far longer, but keep to the factory schedule. Without black soot cycling through, the oil won’t darken right away — still, standard service intervals are worth following.
Q: Will the truck warm up slower in cold weather after this?
A: A touch slower, yes. With the cooler no longer using exhaust heat to preheat coolant, the engine takes a few extra minutes to reach temperature on freezing mornings, though cabin heat still works normally.
