Camshafts Kelford Cams for Mazda Miata 323 B6 NA 272/264

NA Stage 3 racing cams for Mazda B6 engines found in the MX-5 Miata. Good improvement in mid-range to high rpm power compared to OEM cams. Suited to engines with free flowing intake and exhaust systems. Great with ITB intake systems. Great upgrade for cars used for race and rally. Kelford Cams recommend KVS12 valve spring upgrade.
