    Wahler is renowned manufacturer of exhaust gas recirculation (EGR) valves and tubes as well as engine thermostats for both on- and off-road applications. The company is owned by global powertrain supplier BorgWarner that utilizes EGR valve, cooler and tube technologies to provide premium products.

    Without exception, Wahler products are installed either directly on engines or in their immediate vicinity. This means that they must withstand both the radiated engine heat and the high temperatures of cooling media and exhaust gases for whose control and transport they are designed. Accordingly, Wahler products perform with the utmost reliability at all temperatures and in the most challenging conditions.

    Wahler manufactures thermostats that selectively regulate the temperature of cooling circuits (water, oil and air). The company's valves and flaps, as components of exhaust gas recirculation systems, control the travel and flow volume of exhaust gases. Wahler pipes and hoses make up the many connections required in engines to transport hot exhaust gases as well as coolants and lubricants.

    Because the functions of Wahler products directly impact engine performance and service life, the company is dedicated to ensuring their high quality at all times. Throughout the various manufacturing phases, this constant applies to both the quality of materials and the operating characteristics of Wahler products.

    So Far, So Good
    Out with the old, in with the new. The part fits perfectly in place of the old one and works well. My only complaint is that the new part had a slightly larger circumference around the outside than the old part. This meant I had to use pliers to tighten it down, rather than a socket. Not a big deal.
