Maruha's F Cams for the intake and exhaust are a great upgrade to stock, giving a little more duration and lift for more power while still maintaining reliability. Mazda's own VVT system is already inpressive, but with the combination of Maruha's F Cam pushing the powerband up higher, will make for a fun street/track car.
