FITMENT
- 2010-Present Cummins Volvo, Peterbilt, Mack, International, Freightliner, Kenworth with the ISX15 CM2250 / CM2350 engines.
DESCRIPTION
Product Overview
-
On 2010+ Cummins ISX15 engines (CM2250/CM2350), bypassing or removing the EGR loop leaves high-pressure exhaust manifold ports exposed to extreme heat and backpressure. Without precision sealing hardware at the manifold junction, extreme thermal cycling quickly causes gasket blowout, severe drive-pressure leaks, and lost turbo energy.
- Built for high-temp exhaust containment, this Cummins ISX15 Hot-Side EGR Delete Block Off Plate delivers a complete, leak-free seal at the exhaust manifold connection. Machined from heavy-duty steel to resist warping, it securely seals off hot-side exhaust gas delivery, maintains proper turbine drive pressure, and completes a key sealing anchor for Stage 2 EGR delete setups.
Key Features
- Blocks the hot-side exhaust port with a 6061-T6 billet plate that holds up to the extreme heat cycling between the manifold and the EGR system.
- Laser-cut and CNC-machined to exact OEM flange specs so it bolts straight on with zero modification.
- Forms a permanent barrier that stops hot exhaust gas from leaking back into the EGR circuit after component removal.
- Resists thermal cycling, oil, engine fluids, and rust with a corrosion-resistant anodized finish.
FAQ
Q: Where does this EGR block-off plate get installed?
A: It mounts on the hot-side EGR connection between the exhaust manifold and the EGR system on ISX15 engines, sealing the exhaust-side EGR passage after the EGR components are removed.
Q: What is this block-off plate actually for?
A: It seals the factory hot-side EGR exhaust connection, creating a physical barrier that stops hot exhaust gases from entering the EGR system once the components are gone.
Q: Does this block-off plate boost engine performance?
A: Its job is to properly seal the EGR exhaust passage after removal. Any performance gains depend on tuning, engine condition, and other modifications.
Q: Is this single plate enough to replace the whole Stage 2 kit?
A: No. This product contains only the single intake block-off plate. While it seals the intake manifold entry, a complete Stage 2 EGR Delete Kit also carries the extra plates, threaded plugs, and fittings needed to close off the exhaust manifold, EGR valve, and EGR cooler coolant lines.
