Function of this part

The EGR (exhaust gas recirculation) system routes a controlled amount of exhaust gas back into the intake. This lowers combustion temperatures and helps reduce NOx emissions.

Why this part matters

Because EGR flow is monitored closely by the engine management system, issues with EGR valves or coolers quickly trigger fault codes and derates. Keeping the EGR system in good working order is key to reliability and emissions compliance.

About the brand

Cummins engine parts are trusted for reliable power in a variety of heavy-duty truck and equipment applications.

Fitment & usage

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Highly Recommended Dress Shirt
Fit Type: Regular Fit, Color: White, Size: Medium
Honestly, I Love It. Fits Great, Neck Isn't Too Tight Like Most Shirts, And It's Comfortable. It Is 100% Cotton, So Dont Forget To Iron It Before Wearing It. High Quality Dress Shirt. Highly Recommended.

Surprisingly good shirt for the price
Fit Type: Regular Fit, Color: White, Size: XX-Large
I’m generally pleased with my purchase. I got a 2XL because the website it would fit my neck. Around the waist it fit similar to Amazon Essentials work shirts (like mechanics use which I find comfortable). It was snug around the waist when sitting, but I can’t complain because I have a belly. I did find the neck snug when buttoning the top button so it means the neck is 18 or 18.5 and I wear a 19/19.5 to have 1-2 fingers space in the collar. The shirt is surprisingly thick like Amazon’s work shirts, much thicker than other dress shirts from another brand. And I am pleased that this shirt has button holes like other Amazon shirts does, all vertical button holes except the last one at the bottom which is horizontal. That feature keeps the shirt from unbuttoning itself during daily movement at the office. A very nice feature! I was a little disappointed in how it was packaged however but I have to press and wash it anyway.

Comparable to high end mens shops!
Fit Type: Regular Fit, Color: Blue, Size: Large
Beautiful, heavy blue Oxford comparable to upper end mens store at 75% less! Full cut, great for casual wear or sending out for professional starching. Downside, no pocket, but I had mine monogramed wear the pocket would be and it looks like an expensive dress shirt. I bought more (with pockets) in blue & white
