ATP 105006 Exhaust Manifold Heat Riser

Heat Riser

The heat riser is a very important emission devise. It's purpose is to heat the intake manifold on cold start up by redirecting exhaust gas through the intake manifold. As vehicles age, these parts can become seized or corroded to the point that they no longer operate. Broken heat risers can cause the vehicle to run poorly. ATP heat risers are made to fit and function just like the original part ensuring long life and durability.
