Beck/Arnley Fuel Injection Plenum Gasket P/N:037-4841
Beck/Arnley 037-4856 fuel injection plenum gasket for the 1999-2000 Mazda Miata 4-cylinder 1.8L seals the plenum joint against air leaks. Air that slips past a worn plenum gasket enters the engine unmetered.
A rough idle, a hiss from under the hood or a lean-condition code can point to a worn plenum gasket. A cracked vacuum hose or a faulty idle air control valve can also be behind those signs, so find the cause before you replace anything.
This gasket is a direct-fit replacement for the 1999-2000 Mazda Miata 4-cylinder 1.8L, which takes one, and it matches OE form, fit and function.
