Cummins ISX15 Delete Kit: A sturdy EGR solution for compatible engines

So if you’re hunting for a Cummins ISX15 delete kit and you care about it actually holding up, then yeah, you want something made with good materials and not just random machining. The OSIAS ISX EGR Delete Kit is meant for Cummins ISX15 CM2250 plus CM2350 engines, from 2010 through 2024, and it comes as a full hardware setup for off-road plus race use. It’s put together with premium parts, and the pieces are precision-machined, so it’s supposed to fit right and stay durable.

Made for Cummins ISX15 engines (CM2250/CM2350)

OSIAS engineered this delete kit specifically around Cummins ISX15 engines that have CM2250 or CM2350 ECMs. That covers model years 2010–2024, and the idea is simple: the kit seals the EGR valve and EGR cooler using precision-machined plates and fittings. OSIAS also says it’s for off-road and race purposes only and it doesn’t meet emissions rules for street driven vehicles, so keep that in mind.

Materials that are built to last

One thing OSIAS leans on is construction quality, and the kit’s main components are picked for the tough conditions diesel engines deal with daily.

You get CNC-machined aircraft-grade 6061 billet aluminum plates with an anodized finish, which helps slow down corrosion. There are also 304 stainless steel plates and plug fittings, which bring strong resistance to rust and also handle high temperatures well. For the sealing side of things, the kit includes a graphite gasket, rated up to 1200°F, which is there to keep things sealed during real-world operation.

Precision-machined, so fitment doesn’t turn into a guessing game

When you’re installing engine hardware, even small misalignment can become annoying fast. OSIAS uses laser-cut components, and they’re made for compatible CM2250 and CM2350 engine setups. The box also includes all required installation hardware, so you’re looking at a more bolt-on style install for the engines it’s meant for.

Built to survive heavy-duty stress

Commercial diesel engines see nonstop vibration, pressure swings, and nonstop heat. OSIAS designed the kit to deal with thermal cycling, vibration, and pressure fluctuations, using durable components intended to hold stable over time. In short, it’s aimed at long-term reliability for compatible off-road environments.

Performance-oriented intent, minus the EGR mess

OSIAS claims the kit helps eliminate EGR related carbon buildup, which can support better engine efficiency and power output. It’s also intended to reduce exhaust gas temperatures (EGT), which may help extend turbocharger life. For non-turbo setups, the kit is aimed at removing the EGR system fully without needing extra components. Turbocharged applications do require an aftermarket turbo line, and that part is sold separately.

What’s in the kit

The OSIAS package includes everything needed for installation on compatible engines:

4 plates  

1 graphite gasket  

5 plug fittings  

The required bolt-on hardware is included in the package too.

So why pick the OSIAS Cummins ISX15 delete kit?
