This was the exact replacement for my furnace. It even came with a new gasket, which I chose not to use because the old one was intact. Took about 20 minutes to install. Involves removing 5 screws, to small hoses, and a hose clamp. HVAC company quoted me a $600 to replace, this cost less than $100 and 20 minutes of my time.
