The Mazda Miata Exhaust Manifold sweeps exhaust gases from the inline four engine and maintains lively power and clean cabin air. This four runner unit is bolted to the cylinder head with a leak-proof gasket which collects the flow of combustion, feeds the catalytic converter, and prevents reversion to the intake to ensure that fresh charge flows in immediately. Such a step yields the swift throttle response that drivers are fond of and has made the part very stable in all the generations of the roadster. With stout cast iron on NA and NB cars, or lighter stainless steel on NC and ND models, the manifold obviously fits all the two-seat chassis due to its four tubes and is designed to fit all four cylinders of every Mazda sports icon. The Exhaust Manifold eliminates fumes quickly and allows the computer to maintain equal ratios of air and fuel in the mixture, allowing the engine to burn well to earn better mileage and reduce emissions. The tight seal also protects the occupants against harmful gases and thus the component acts as a safety barrier and a performance booster. When cracks develop, horsepower and fuel economy are easily lost, hence immediate replacement is made to restore pep and power. And this is where the spirited Miata starts breathing freely. Due to a common mounting location and sensor ports allowed by Mazda, manifolds in NA to ND cars provide wide compatibility, so any Miata manufactured since 1989 can be upgraded or swapped with stock parts without difficulty. Drivers also value that the Exhaust Manifold does not require regular service but can take the heat of extreme temperatures with thick flanges, corrosion-resistant metal, and a shape that evenly distributes pressure pulses at high revs. The lightweight roadster has these characteristics from the factory that make it jump off the line, take corners with consistent power, and meet rigorous emission standards, hence the reason Mazda continues to match this proven component with its successful convertible.
