Acura MDX 07-09 underbody catalytic converter 3.7L V6

The necessary property of honeycomb ceramic catalyst substrate used in cars as follows:
1.High specific surface area: ensure exhaust gas could contact weigh catalyst enough.
2.Stable water absorption: guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it's no waste for too thick coating.
3.Warm up characters: after starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time.
4.Low exhaust resistance: ask exhaust resistance of substrate to engine low, so that it won’t affect the performance of engine.
5.High intensity: substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed.
6.Perfect assembly: substrates are parts of exhaust; perfect appearance and exact dimension could ensure assembly perfect.
