Description
Built around the requirements of 1990-1999 Mazda Miata 1.8L (BP056) DOHC 16 Exhaust, this Race Master exhaust valve family gives engine builders a focused way to select the dimensions their cylinder-head combination calls for. The parent listing is distinguished by Part #11101-1, which should be cross-checked against the rest of the engine combination.
If the 1990-1999 Mazda Miata 1.8L (BP056) DOHC 16 Exhaust cylinder head has been ported, fitted with oversized seats, or changed from its original valvetrain layout, confirm the required valve measurements after machining rather than using a stock-size assumption.
