The Bostech EGR Cooler Upgrade EGR900 for your 2002-2006 Mercedes MBE906 solves the common EGR cooler failures on your truck. Most OEM coolers are failing due to cracking, which causes the water and exhaust to mix, or from becoming clogged with exhaust deposits. We have developed a process making the cooler much more reliable and maintenance free.

The Bostech design uses T304 stainless steel tubing to replace the turbulator design used inmost OEM coolers. The stainless steel tubing is tig welded to precision laser cut plates that are attached to the cooler housing. This will ensure the cooler will operate under the toughest of environments. This is a must for mass transit vehicles like school buses, ambulances, and wreckers/rollbacks.
