How to Buy a Good Quality Exhaust Gas Recirculation (EGR) Tube

Good Quality EGR Tube

Exhaust gas recirculation tubes (EGR tubes) are responsible for moving a very small amount of gas from the exhaust manifold to the intake manifold in order to help reduce emissions of nitrous oxide. This tube is the key point of passage between the EGR system, directing gasses from the internal combustion engine through the system and eventually circulating them back into the intake manifold and the combustion chamber to be burned again.

The EGR tube often becomes clogged over time with residue from the exhaust that flows through it. The tube is also exposed to very high heat from the gasses that pass through it, potentially causing leaks as well.

A non-functional or low-functioning EGR tube can cause you to fail emissions testing, can cause knocking in your engine, and can also cause pinging noises if it’s not recirculating gases properly.

When it's time to replace your old EGR tube, keep a few things in mind to make sure you’re getting a good quality EGR tube:

  • Be sure you’re getting new or OEM (original equipment manufacturer) parts: This specific part is made to fit only one type of EGR valve, and getting the incorrect version will cause problems with the fit and seal.

  • Replace EGR valve at the same time: Replacing the EGR valve at the same time you replace the EGR tube is always a good idea, to ensure that you’re getting a solid match.

Keeping your vehicle running clean requires having a correctly-installed and working exhaust gas recirculation tube and valve.
