FITMENT
- 2010-Present Cummins Volvo, Peterbilt, Mack, International, Freightliner, Kenworth with the ISX15 CM2250 / CM2350 engines.
DESCRIPTION
Product Overview
-
When removing EGR components on 2010+ Cummins ISX15 engines, open factory EGR ports create severe exhaust leaks, engine bay soot buildup, and power-robbing pressure loss in the exhaust tract.
- This ISX15 Exhaust-Side EGR Sealing Kit delivers a complete, leak-free block-off solution for the OEM exhaust outlet. By permanently capping off unused EGR passages after component removal, it eliminates exhaust leaks, preserves drive pressure, and ensures a clean, heavy-duty engine setup.
Key Features
- Seal high-pressure EGR exhaust leaks at the manifold source to keep EGT energy in the turbo circuit and engine bay temperatures cooler
- Withstand extreme exhaust gas temperatures with heavy-duty 304 stainless steel construction that resists thermal cracking and burn-through
- Bolt directly onto the OEM flange pattern with precision laser-cut fitment — no drilling, grinding, or custom fabrication needed
- Resist corrosion from oil, coolant, and road chemicals with an anodized surface coating built for commercial truck service life
FAQ
Q: What is this EGR port plug used for?
A: It seals the factory hot-side EGR exhaust outlet on the manifold after EGR cooler and valve removal. It blocks the unused exhaust passage to prevent leaks, maintain proper backpressure, and keep hot gases contained.
Q: Is this the same as an EGR block-off plate?
A: No. This is a round port plug designed specifically for the circular exhaust outlet opening on the manifold. A block-off plate, by contrast, is a flat sealing plate used on different rectangular or flat EGR connection points.
Q: Is this a complete EGR delete kit for the ISX15?
A: No. This is an individual sealing component for the hot-side exhaust port. A full Stage 2 EGR solution may require additional block-off plates, coolant bypass plugs, and sealing hardware to close all EGR-related connections on the engine.
Q: Which trucks and engines does this fit?
A: This plug fits 2010-Present Cummins ISX15 CM2250 and CM2350 engines commonly found in Volvo, Peterbilt, Mack, International, Freightliner, and Kenworth heavy trucks.
