TruckTok 2002-2007 ISX CM870 Stage 2 EGR Delete Plug Kit Stage 1 Plates and Plugs Generic

FITMENT

• 2002-2007 Cummins Volvo, Peterbilt, Mack, International, Freightliner, Kenworth with the ISX CM870 Engines.

DESCRIPTION

Product Overview

• The 02–07 ISX CM870 was one of the early Cummins 15L platforms to utilize EGR technology for emissions compliance. Over time, factory EGR components such as the EGR valve, crossover passages, and cooler can experience soot buildup, sticking issues, and potential coolant leakage concerns.
  
• The Stage 2 EGR Plug Kit is a complete sealing solution designed for competition and off-road applications. Compared with basic block-off solutions, this kit seals multiple EGR-related exhaust, intake, and coolant passages after component removal.

• Machined Billet Aluminum: Precision CNC-machined from durable billet aluminum for strength and resistance to warping under high engine temperatures.
  
• Helps Prevent Coolant & Exhaust Leaks: Properly seals unused EGR passages after removal, helping reduce potential leakage and contamination issues.
• Cleaner Intake Airflow: Helps prevent exhaust gas recirculation into the intake system, reducing soot buildup and supporting cleaner engine operation.
• Complete Stage 2 EGR Sealing Solution: Seals multiple EGR-related connections, including valve ports, crossover passages, exhaust connections, and coolant passages after component removal.

FAQ

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

A: This kit seals EGR-related exhaust, intake, and coolant passages after EGR component removal on ISX CM870 engines, helping prevent leaks and unwanted exhaust recirculation through unused ports.

Q: Why do I need an EGR block-off plug kit?

A: After removing EGR components, the remaining openings must be properly sealed. This kit provides block-off plates, plugs, and gaskets to help prevent exhaust leaks, coolant leaks, and contamination issues.

Q: Are CM870 and CM871 EGR kits interchangeable?

A: No. CM870 and CM871 engines use different EGR system layouts and sealing points. Each kit is designed specifically for its corresponding engine model, so please confirm your engine model before purchase.

Q: Does this kit help reduce soot buildup?

A: By preventing exhaust gas from being routed back into the intake system, the kit helps reduce soot accumulation inside intake passages and supports cleaner airflow.
