EGR Coolers

Looking for Roadwarrior EGR Coolers?

Roadwarrior EGR coolers take the air leaving your engine and recirculates it back inside the engine to cool the exhaust gases which helps reduce emissions, lowers combustion temperatures, and for better overall engine health.

Why do I need an EGR Cooler?


EGR coolers work to reduce harmful emissions by cooling down engine air temperature. The air which has been cooled by the EGR cooler re-enters the engine and helps to reduce high temperatures from general use. For example, cylinder head temperature and other hot engine components, the EGR cooler helps these components operate optimally. Due to the increased airflow EGR coolers lower combustion temperatures by diluting the air/ fuel mixture, this cooler air helps the dilution process and is good for your engine.  


EGR systems help to prevent pollutants from forming in your engine. Pollutants like Nitrogen oxide (NOx) and Ozone (O3) can form under very high engine temperatures. This extreme heat combines nitrogen and oxygen atoms together resulting in those harmful gasses.

An EGR cooler that is not functioning properly can result decreased engine health. Complete failure of your EGR cooler is a serious issue which could cause engine damage.

Roadwarrior's catalogue is always growing! Let us know which part number you are looking for and we will find your cross and get back to you. If your part is not currently in production, we can consider building it for you. 

Better Coating, Better Performance.

Roadwarrior is the only manufacturer to use Metalcor® catalyst technology across its entire range of Diesel Oxidation Catalysts (DOCs) and Selective Catalytic Reduction catalysts (SCRs). Metalcor® catalysts feature high activity catalyst coatings fused to thinner, stronger, catalyst substrates to guarantee maximum performance under the harshest conditions.

Metalcor® catalyst coatings are designed and produced in our own labs. We then inspect each unit to ensure you get more fuel efficiency, lower consumption of DEF, and long term performance from your heavy duty engine!


Roadwarrior Has You Covered!

All Roadwarrior emissions parts carry a full value 12 month warranty.

LightningVolt lithium batteries carry a full value 30 month warranty.

To make the process hassle-free, our parts have a metal nameplate with the serial number, so even after 500,000 miles of service, it’s still easy to identify. This avoids the common problem of serial numbers printed on stickers that burn off after the first start-up, making them impossible to return. Our failsafe system allows us to work in your interests, honouring claims for on-road and off-road replacements, and giving you peace of mind.

And since Roadwarrior parts are designed to meet or exceed OEM specifications, you can rest easy knowing our direct fit parts will take the problems out of your aftertreatment without interfering with your OEM warranty.

Next Day Is Nice, Same Day is Better!​

A faulty emissions control system can cost you thousands in wasted man-hours as your heavy equipment sits in the shop awaiting a new part. Whether it’s a truck behind on orders, a bus that can’t take passengers, or heavy machinery delaying construction deadlines, Roadwarrior can get you moving again! 

Roadwarrior has twelve warehouses across the U.S.A. and Canada, which can deliver the most popular aftertreatment parts in 1-2 days. With over 1,000 DPFs, DOCs and SCRs on offer, Roadwarrior offers the largest aftertreatment catalogue.
