FITMENT

  • 2007-2010 Cummins Volvo, Peterbilt, Mack, International, Freightliner, Kenworth with the ISX CM871 Engines.

DESCRIPTION

Product Overview

  • The 2007–2010 Cummins ISX CM871 is a proven heavy-duty engine, but its factory EGR system operates under extreme heat and exhaust conditions. Over time, carbon buildup, sticking EGR components, and EGR cooler issues can lead to reduced airflow, poor performance, and increased maintenance.
  • The Stage 2 EGR Block Plate & Plug Kit seals EGR-related openings after component removal, helping prevent exhaust gas from re-entering the intake system. Designed for heavy-duty diesel builds and off-road applications, it provides a cleaner and more reliable EGR sealing solution.
Key Features
  • Heavy-Duty material: Features CNC-machined aluminum components with durable 304 SS plates and fittings for excellent strength and heat resistance.
  • Helps Protect Engine Reliability: Properly seals remaining EGR-related passages to help prevent common leaks and contamination issues after EGR component removal.
  • Reduced Soot Buildup & Cleaner Airflow: Helps keep exhaust gases from re-entering the intake system, reducing soot accumulation and supporting consistent engine airflow.
  • Complete Stage 2 EGR Sealing Solution: Seals multiple EGR valve and cooler ports after component removal, helping prevent exhaust gas flow and coolant leakage through unused passages.

FAQ

Q: What does this Stage 2 EGR Block Plate & Plug Kit do?

A: Seals EGR-related exhaust and coolant passages after EGR component removal on ISX CM871 engines. Helps prevent exhaust gas flow and coolant leakage through unused EGR connections.

Q: What is the difference between Stage 1 and Stage 2 EGR kits?

A: Stage 1 kits typically block a single EGR connection, while this Stage 2 kit provides a more complete sealing solution with multiple block-off plates and plugs for additional EGR-related ports.

Q: What happens if I remove the EGR components but leave the ports open?

A: Open EGR connections can allow exhaust leaks, coolant loss, and contamination. Proper block plates and plugs help create a secure seal and protect surrounding engine components.

Q: What benefits does this EGR Block Plate & Plug Kit provide?

A: This kit provides a secure way to seal EGR-related exhaust and coolant passages after EGR component removal. It helps reduce potential exhaust leaks, coolant leaks, and soot contamination while maintaining a cleaner engine setup for heavy-duty diesel applications.

290K miles since delete — ISX going strong

Installed this kit on my 2007 Pete 379 at 680K miles when the EGR differential pressure sensor failed for the third time. Figured why keep throwing sensors at a system that is killing my engine. 290K miles later the truck has 970K on the clock and the bottom end is still tight. Blackstone reports show soot at 0.1% at 15K-mile oil changes instead of 1.8% at 10K. I credit this delete with doubling the life of my ISX.

Pretty good

When u delete u have to change the water pump to a 2007 without the egr port on it

Fleet mechanic — installed 4 of these so far

I work on a fleet of 12 ISX-powered trucks. The CM871 EGR system is the single biggest source of downtime. Cooler failures, valve sticking, soot packing the intake. We have installed four of these TruckTok Stage 2 kits so far and every truck has come back cleaner on oil analysis and with fewer driver complaints. The kit is complete — you do not need to source anything separately. Plates and plugs are machined aluminum, not cast, so they will not crack.

Make sure your tuner is ready before install

The kit itself is solid — everything fit my 2008 ISX perfectly. But I made the mistake of installing it before having the demandate file ready. The truck threw every EGR-related code and went into derate. Had to wait two days for the tuner to send the file. Learn from my mistake: have the tune loaded before you turn a single bolt. Once the tune was in, the CEL cleared instantly and the truck has run flawlessly.

Shop quoted $7500 for OEM EGR replacement — did this instead

2010 Freightliner Cascadia. EGR cooler was clogged and the valve was stuck open, dumping soot into the intake. Dealer quote to replace everything OEM-style was $7500 parts and labor. I am an owner-operator — I don't have $7500 lying around. This plug kit plus a demandate tune cost me less than $1500 total. The truck runs cooler at highway speed and the turbo spools with less lag. If you are on the fence about deleting your ISX, just do it.

Owner-operator here — paid for itself in fuel alone

2008 Kenworth W900 with the CM871. Before delete I was averaging 5.8 mpg running I-80. After this plug kit, a tune, and a turbo swap I am at 7.1 mpg. That is $400 a week in fuel savings. The kit paid for itself in the first two weeks. The aluminum plates are thick and the mating surfaces are machined flat — no exhaust leaks. This is the best money an ISX owner can spend.

ISX EGR cooler was dead at 420K — this fixed it permanently

2009 Peterbilt 389 with the ISX CM871. EGR cooler ruptured at 420K and dumped coolant into cylinder 3. Caught it before it hydrolocked. Bought this Stage 2 plug kit — aluminum plates for the intake and exhaust ports, threaded coolant plugs for the block, and the EGR valve block-off. Had my mechanic install it in about 4 hours while doing a mandated overhaul. 30K miles later and the truck pulls better than it ever did with the EGR system. No more coolant consumption, oil stays clean past 15K miles.
